Custom LDraw File Syntax Additions

2020-02-22T01:54:53Z

Michael Horvath: /* MLCad */ add a missing MLCAD meta tag

Sometimes, [[App Developer|authors]] of LDraw-related [[software]] add special custom syntax elements to the [[LDraw file format]].

This can create various problems when
* the semantics of such syntax changes between software versions
* different software interprets them differently
* files get widespread which make use of that custom syntax, without it being a standard.

For that reason, doing so in general is a Bad Idea (TM).

However, this in the past has happend quite in some instances.

This page tries to list all the existing custom syntax elements.

LGEO

2019-07-05T15:14:20Z

Michael Horvath: edit

{{Stub}}

'''LGEO''' is a library of LEGO parts modeled by [[POV-Ray]] primitives.

When exporting LDraw parts to POV-Ray format, tools like [[LDView]] can use an [[XML]] file,
usually named <code>LGEO.xml</code>, to substitute dedicated parts by their LGEO implementations. An older tool [[L3P]] uses the two files <code>lg_elements.lst</code> and <code>lg_colors.lst</code> to accomplish much the same thing, as well as for indicating whether to switch over to using Anton Raves' POV-Ray parts instead.

Starting from the original library by Lutz Uhlmann, many people edited and added parts to it.
This sadly has led to a tree of variations, not a single collection.
This tree is shown here:

User:Owen Burgoyne/POV-Ray Tutorial

2019-07-01T12:49:11Z

Michael Horvath: /* Requirements */ fix link

This tutorial is a '''WORK IN PROGRESS'''.
<hr/>
[[File:Pyramid POV-Ray Radiosity Final.png|thumb|300px|James Jessiman's pyramid model, rendered in POV-Ray.]]
The purpose of this guide is to take an already-built [[LDraw]] model and then render it in [[POV-Ray]] to create a near-realistic image. The guide itself will not necessarily give you ''all'' the answers on how to create exactly what you want, but will hopefully get you started in the right direction and perhaps even lead you on to investigating and mastering certain rendering techniques.

For the purposes of this tutorial, I will be using James Jessiman's pyramid model included with LDraw.

==Requirements==
For the purposes of this guide I have used the following:

*The [[LDraw]] library
*[[MLCad]] 3.40
*[[LDView]] 4.2 beta 1
*[[LGEO]] parts library
*[http://www.povray.org/beta/ POV-Ray 3.7 RC7]
* A plain text editor, such as Notepad

The first four can all be obtained directly from the [[LDraw All-In-One Installer]] (AIOI), although my LGEO parts pack requires manual installation.

The LDraw AIOI currently contains POV-Ray 3.6, but I recommend uninstalling this if you already have it and installing POV-Ray 3.7. Although still currently in beta, I have had no issues using it and it contains the ability to use more than one CPU, allowing for much faster rendering when using a multi-core system.

The guide also assumes that you are running the above on Windows. (I have no Mac or Linux experience, so would not able to advise on the correct file paths for installation.)

==Setting up LDView==

[[LDView]], which is used to export the LDraw model to the POV-Ray format, automates a lot of things, although there are a few things worth taking into account.

===Image aspect ratio===

The first thing you may want to set is the aspect ratio of the final image. Once you have your model open within LDView, you can set LDView's display aspect ratio from the menu under '''View > Standard Sizes'''. Each view size shows the relevant aspect ratio that it conforms to in brackets. For the purposes of this tutorial, I'll be using '''1280 x 720 (16:9)''', the ratio used by a lot of modern monitors.

To ensure that this carries over to your render, you need to set a matching ratio in the LDView export window. You can do this by going to '''File > Export...''' and then the '''Options...''' button, and selecting the appropriate option under '''Aspect Ratio'''. You can also use '''Current LDView aspect ratio''', but need to ensure that you know what you used when selecting the image size within POV-Ray.

However, for this to work with a lot of wider aspect ratios you need the same aspect ratio available within POV-Ray, and this is explained under the "quickres.ini" entry below.

===Include files===

LDView gives you the ability to use "include" files within your POV-Ray file, in case there are settings you always use but are not default options within the file that LDView generates. This means you can set other values for things such as floor colour, background colour, etc.

An "include" can be saved to any location, and the file path can then be inserted into the relevant field.

Below is an example of the text that I use in the top include file:

<pre>// Floor settings
#declare LDXFloorR = 0.9; // Floor Red
#declare LDXFloorG = 0.9; // Floor Green
#declare LDXFloorB = 0.9; // Floor Blue
#declare LDXFloorAmb = 0; // Floor Ambient
#declare LDXFloorDif = 0.9; // Floor Diffuse

// Fog
#if (LDXFloor != 0)
fog {
distance LDXRadius*100
color rgb 1
}
#end</pre>

The '''Floor settings''' section automatically changes the floor variables to something I find works better, meaning I don't have to edit each file that LDView exports.

The '''Fog''' section creates a fogging effect in the background, which softens the horizon when the POV-Ray camera is pointing at a shallow angle.

==Setting up the LGEO library==

If you've installed the LGEO library from the AIOI to the default location, then it should be located at '''C:\Program Files\LDraw\LGEO'''.

Although updated by Lutz Uhlmann in 2008, there are still a few errors in the library, some of which are simply compatibility issues with any version of POV-Ray higher than 3.1. Where possible, I have fixed any files that I have come across, as well as create some new files, which can be found in the LGEO Parts Pack listed above.

The file itself mainly contains LGEO files (marked with '''lg_''' at the beginning of the file) which can simply be copied to LGEO's '''C:\Program Files\LDraw\LGEO\lg''' folder.

It also contains a file called '''LGEO.xml''' which must be copied to the LDView installation folder.

==Setting up POV-Ray==

===povray.ini===
To function properly with the LGEO library, POV-Ray needs to be told where to find the library files, and this is done via the '''povray.ini''' file. To edit this, within the POV-Ray menu go to '''Tools > Edit master POVRAY.INI'''. This will open the file as a text file, and give you some basic explanation on how to add or modify settings within this file.

You need to ensure that library paths are included in the file, pointing to the installation folder for LGEO. If using the AIOI, this is installed by default to the '''C:\Program Files\LDraw''' folder, so the following lines would need to be added to the end of the file:

<pre>Library_Path="C:\Program Files\LDraw\LGEO"
Library_Path="C:\Program Files\LDraw\LGEO\ar"
Library_Path="C:\Program Files\LDraw\LGEO\lg"</pre>

If you're using a 64-bit version of Windows, then you may need to change '''Program Files''' to '''Program Files (x86)'''.

===quickres.ini===
POV-Ray includes its own resolution definitions, stored in a file called '''quickres.ini''', which allows you to quickly set your desired image output size. These are accessed via a drop-down box shown at the top left of the POV-Ray window, but the available options are fairly limited.

To alter these settings, within the POV-Ray menu go to '''Tools > Edit resolution INI file''' and the file should then open up as a text file. You should see a number of different resolutions, mainly set to the 4:3 ratio (640x480, 800x600, etc.), along with [http://en.wikipedia.org/wiki/Spatial_anti-aliasing anti-alias] switches. For example:

<pre>[800x600, No AA]
Width=800
Height=600
Antialias=Off</pre>

or

<pre>[800x600, AA 0.3]
Width=800
Height=600
Antialias=On
Antialias_Threshold=0.3</pre>

This rather limits the available ratios, such as 16:9 (widescreen) or 2.35:1 (anamorphic widescreen). Therefore you need to specify your own. To make it easier to pick out which aspect ratio I need, I often specify this in the preset, as in the below example:

<pre>[800x340 2.35:1, No AA]
Width=800
Height=340
Antialias=Off

[800x450 16:9, No AA]
Width=800
Height=450
Antialias=Off</pre>

You can also specify further sizes by adding variations on the above, and add anti-aliasing to each resolution by changing '''Antialias=Off''' to:

<pre>Antialias=On
Antialias_Threshold=0.3</pre>

===Custom inserts===
POV-Ray includes the option to insert pre-defined parameters into a POV-Ray file, either from the main menu ('''Insert''') or by right-clicking the Editor window.

The purpose of setting these up for rendering LDraw models is to make it easier to insert often-used options, such as radiosity settings or HDRI lighting environments. By default, POV-Ray will store the "Inserts" folder here:

<pre>C:\Users\%USERNAME%\Documents\POV-Ray\v3.7\Insert Menu</pre>

For the purposes of this tutorial, I will be using James Jessiman's pyramid model included with LDraw.

==Requirements==
For the purposes of this guide I have used the following:

*The [[LDraw]] library
*[[MLCad]] 3.40
*[[LDView]] 4.2 beta 1
*[[LGEO]] parts library
*[http://www.povray.org/beta/ POV-Ray 3.7 RC7]
* A plain text editor, such as Notepad

The first four can all be obtained directly from the [[LDraw All-In-One-Installer]] (AIOI), although my LGEO parts pack requires manual installation.

The LDraw AIOI currently contains POV-Ray 3.6, but I recommend uninstalling this if you already have it and installing POV-Ray 3.7. Although still currently in beta, I have had no issues using it and it contains the ability to use more than one CPU, allowing for much faster rendering when using a multi-core system.

The guide also assumes that you are running the above on Windows. (I have no Mac or Linux experience, so would not able to advise on the correct file paths for installation.)

==Setting up LDView==

[[LDView]], which is used to export the LDraw model to the POV-Ray format, automates a lot of things, although there are a few things worth taking into account.

===Image aspect ratio===

The first thing you may want to set is the aspect ratio of the final image. Once you have your model open within LDView, you can set LDView's display aspect ratio from the menu under '''View > Standard Sizes'''. Each view size shows the relevant aspect ratio that it conforms to in brackets. For the purposes of this tutorial, I'll be using '''1280 x 720 (16:9)''', the ratio used by a lot of modern monitors.

To ensure that this carries over to your render, you need to set a matching ratio in the LDView export window. You can do this by going to '''File > Export...''' and then the '''Options...''' button, and selecting the appropriate option under '''Aspect Ratio'''. You can also use '''Current LDView aspect ratio''', but need to ensure that you know what you used when selecting the image size within POV-Ray.

However, for this to work with a lot of wider aspect ratios you need the same aspect ratio available within POV-Ray, and this is explained under the "quickres.ini" entry below.

===Include files===

LDView gives you the ability to use "include" files within your POV-Ray file, in case there are settings you always use but are not default options within the file that LDView generates. This means you can set other values for things such as floor colour, background colour, etc.

An "include" can be saved to any location, and the file path can then be inserted into the relevant field.

Below is an example of the text that I use in the top include file:

<pre>// Floor settings
#declare LDXFloorR = 0.9; // Floor Red
#declare LDXFloorG = 0.9; // Floor Green
#declare LDXFloorB = 0.9; // Floor Blue
#declare LDXFloorAmb = 0; // Floor Ambient
#declare LDXFloorDif = 0.9; // Floor Diffuse

// Fog
#if (LDXFloor != 0)
fog {
distance LDXRadius*100
color rgb 1
}
#end</pre>

The '''Floor settings''' section automatically changes the floor variables to something I find works better, meaning I don't have to edit each file that LDView exports.

The '''Fog''' section creates a fogging effect in the background, which softens the horizon when the POV-Ray camera is pointing at a shallow angle.

==Setting up the LGEO library==

If you've installed the LGEO library from the AIOI to the default location, then it should be located at '''C:\Program Files\LDraw\LGEO'''.

Although updated by Lutz Uhlmann in 2008, there are still a few errors in the library, some of which are simply compatibility issues with any version of POV-Ray higher than 3.1. Where possible, I have fixed any files that I have come across, as well as create some new files, which can be found in the LGEO Parts Pack listed above.

The file itself mainly contains LGEO files (marked with '''lg_''' at the beginning of the file) which can simply be copied to LGEO's '''C:\Program Files\LDraw\LGEO\lg''' folder.

It also contains a file called '''LGEO.xml''' which must be copied to the LDView installation folder.

==Setting up POV-Ray==

===povray.ini===
To function properly with the LGEO library, POV-Ray needs to be told where to find the library files, and this is done via the '''povray.ini''' file. To edit this, within the POV-Ray menu go to '''Tools > Edit master POVRAY.INI'''. This will open the file as a text file, and give you some basic explanation on how to add or modify settings within this file.

You need to ensure that library paths are included in the file, pointing to the installation folder for LGEO. If using the AIOI, this is installed by default to the '''C:\Program Files\LDraw''' folder, so the following lines would need to be added to the end of the file:

<pre>Library_Path="C:\Program Files\LDraw\LGEO"
Library_Path="C:\Program Files\LDraw\LGEO\ar"
Library_Path="C:\Program Files\LDraw\LGEO\lg"</pre>

If you're using a 64-bit version of Windows, then you may need to change '''Program Files''' to '''Program Files (x86)'''.

===quickres.ini===
POV-Ray includes its own resolution definitions, stored in a file called '''quickres.ini''', which allows you to quickly set your desired image output size. These are accessed via a drop-down box shown at the top left of the POV-Ray window, but the available options are fairly limited.

To alter these settings, within the POV-Ray menu go to '''Tools > Edit resolution INI file''' and the file should then open up as a text file. You should see a number of different resolutions, mainly set to the 4:3 ratio (640x480, 800x600, etc.), along with [http://en.wikipedia.org/wiki/Spatial_anti-aliasing anti-alias] switches. For example:

<pre>[800x600, No AA]
Width=800
Height=600
Antialias=Off</pre>

or

<pre>[800x600, AA 0.3]
Width=800
Height=600
Antialias=On
Antialias_Threshold=0.3</pre>

This rather limits the available ratios, such as 16:9 (widescreen) or 2.35:1 (anamorphic widescreen). Therefore you need to specify your own. To make it easier to pick out which aspect ratio I need, I often specify this in the preset, as in the below example:

<pre>[800x340 2.35:1, No AA]
Width=800
Height=340
Antialias=Off

[800x450 16:9, No AA]
Width=800
Height=450
Antialias=Off</pre>

You can also specify further sizes by adding variations on the above, and add anti-aliasing to each resolution by changing '''Antialias=Off''' to:

<pre>Antialias=On
Antialias_Threshold=0.3</pre>

===Custom inserts===
POV-Ray includes the option to insert pre-defined parameters into a POV-Ray file, either from the main menu ('''Insert''') or by right-clicking the Editor window.

The purpose of setting these up for rendering LDraw models is to make it easier to insert often-used options, such as radiosity settings or HDRI lighting environments. By default, POV-Ray will store the "Inserts" folder here:

<pre>C:\Users\%USERNAME%\Documents\POV-Ray\v3.7\Insert Menu</pre>

Michael Horvath: wording

{{Stub}}

'''LGEO''' is a library of LEGO parts modeled by [[POV-Ray]] primitives.

When exporting LDraw parts to POV-Ray format, tools like [[LDView]] can use an [[XML]] file,
usually named <code>LGEO.xml</code>, to substitute dedicated parts by their LGEO implementations. The older tool [[L3P]] uses the two files <code>lg_elements.lst</code> and <code>lg_colors.lst</code> to accomplish much the same thing, as well as to indicate whether to switch over to using Anton Raves' POV-Ray parts instead.

Starting from the original library by Lutz Uhlmann, many people edited and added parts to it.
This sadly has led to a tree of variations, not a single collection.
This tree is shown here:

Michael Horvath: note about Lutz's parts in AIOI

{{Stub}}

'''LGEO''' is a library of LEGO parts modeled by [[POV-Ray]] primitives.

When exporting LDraw parts to POV-Ray format, tools like [[LDView]] can use an [[XML]] file,
usually named <code>LGEO.xml</code>, to substitute dedicated parts by their LGEO implementations. The older tool [[L3P]] uses the two files <code>lg_elements.lst</code> and <code>lg_colors.lst</code> to accomplish much the same thing, as well as to indicate whether to switch over to using Anton Raves' POV-Ray parts instead.

Starting from the original library by Lutz Uhlmann, many people edited and added parts to it.
This sadly has led to a tree of variations, not a single collection.
This tree is shown here:

User:Owen Burgoyne/POV-Ray Tutorial

Michael Horvath: /* Requirements */ update notes

This tutorial is a '''WORK IN PROGRESS'''.
<hr/>
[[File:Pyramid POV-Ray Radiosity Final.png|thumb|300px|James Jessiman's pyramid model, rendered in POV-Ray.]]
The purpose of this guide is to take an already-built [[LDraw]] model and then render it in [[POV-Ray]] to create a near-realistic image. The guide itself will not necessarily give you ''all'' the answers on how to create exactly what you want, but will hopefully get you started in the right direction and perhaps even lead you on to investigating and mastering certain rendering techniques.

For the purposes of this tutorial, I will be using James Jessiman's pyramid model included with LDraw.

==Requirements==
For the purposes of this guide I have used the following:

*The [[LDraw]] library
*[[MLCad]] 3.40
*[[LDView]] 4.2 beta 1
*<s>[http://www.digitalbricks.org/ The LGEO library] and my own [https://dl.dropbox.com/u/59864198/LDraw/Other%20Files/LGEO-Update.zip LGEO Parts Pack] (zip file)</s> (ed. See the [[LGEO]] article for the most current info on how to get the LGEO library.)
*[http://www.povray.org/beta/ POV-Ray 3.7 RC7]
* A plain text editor, such as Notepad

The first four can all be obtained directly from the [http://www.ldraw.org/downloads-2/downloads.html LDraw All-In-One-Installer] (AIOI), although my LGEO parts pack requires manual installation.

The LDraw AIOI currently contains POV-Ray 3.6, but I recommend uninstalling this if you already have it and installing POV-Ray 3.7. Although still currently in beta, I have had no issues using it and it contains the ability to use more than one CPU, allowing for much faster rendering when using a multi-core system.

The guide also assumes that you are running the above on Windows. (I have no Mac or Linux experience, so would not able to advise on the correct file paths for installation.)

==Setting up LDView==

[[LDView]], which is used to export the LDraw model to the POV-Ray format, automates a lot of things, although there are a few things worth taking into account.

===Image aspect ratio===

The first thing you may want to set is the aspect ratio of the final image. Once you have your model open within LDView, you can set LDView's display aspect ratio from the menu under '''View > Standard Sizes'''. Each view size shows the relevant aspect ratio that it conforms to in brackets. For the purposes of this tutorial, I'll be using '''1280 x 720 (16:9)''', the ratio used by a lot of modern monitors.

To ensure that this carries over to your render, you need to set a matching ratio in the LDView export window. You can do this by going to '''File > Export...''' and then the '''Options...''' button, and selecting the appropriate option under '''Aspect Ratio'''. You can also use '''Current LDView aspect ratio''', but need to ensure that you know what you used when selecting the image size within POV-Ray.

However, for this to work with a lot of wider aspect ratios you need the same aspect ratio available within POV-Ray, and this is explained under the "quickres.ini" entry below.

===Include files===

LDView gives you the ability to use "include" files within your POV-Ray file, in case there are settings you always use but are not default options within the file that LDView generates. This means you can set other values for things such as floor colour, background colour, etc.

An "include" can be saved to any location, and the file path can then be inserted into the relevant field.

Below is an example of the text that I use in the top include file:

<pre>// Floor settings
#declare LDXFloorR = 0.9; // Floor Red
#declare LDXFloorG = 0.9; // Floor Green
#declare LDXFloorB = 0.9; // Floor Blue
#declare LDXFloorAmb = 0; // Floor Ambient
#declare LDXFloorDif = 0.9; // Floor Diffuse

// Fog
#if (LDXFloor != 0)
fog {
distance LDXRadius*100
color rgb 1
}
#end</pre>

The '''Floor settings''' section automatically changes the floor variables to something I find works better, meaning I don't have to edit each file that LDView exports.

The '''Fog''' section creates a fogging effect in the background, which softens the horizon when the POV-Ray camera is pointing at a shallow angle.

==Setting up the LGEO library==

If you've installed the LGEO library from the AIOI to the default location, then it should be located at '''C:\Program Files\LDraw\LGEO'''.

Although updated by Lutz Uhlmann in 2008, there are still a few errors in the library, some of which are simply compatibility issues with any version of POV-Ray higher than 3.1. Where possible, I have fixed any files that I have come across, as well as create some new files, which can be found in the LGEO Parts Pack listed above.

The file itself mainly contains LGEO files (marked with '''lg_''' at the beginning of the file) which can simply be copied to LGEO's '''C:\Program Files\LDraw\LGEO\lg''' folder.

It also contains a file called '''LGEO.xml''' which must be copied to the LDView installation folder.

==Setting up POV-Ray==

===povray.ini===
To function properly with the LGEO library, POV-Ray needs to be told where to find the library files, and this is done via the '''povray.ini''' file. To edit this, within the POV-Ray menu go to '''Tools > Edit master POVRAY.INI'''. This will open the file as a text file, and give you some basic explanation on how to add or modify settings within this file.

You need to ensure that library paths are included in the file, pointing to the installation folder for LGEO. If using the AIOI, this is installed by default to the '''C:\Program Files\LDraw''' folder, so the following lines would need to be added to the end of the file:

<pre>Library_Path="C:\Program Files\LDraw\LGEO"
Library_Path="C:\Program Files\LDraw\LGEO\ar"
Library_Path="C:\Program Files\LDraw\LGEO\lg"</pre>

If you're using a 64-bit version of Windows, then you may need to change '''Program Files''' to '''Program Files (x86)'''.

===quickres.ini===
POV-Ray includes its own resolution definitions, stored in a file called '''quickres.ini''', which allows you to quickly set your desired image output size. These are accessed via a drop-down box shown at the top left of the POV-Ray window, but the available options are fairly limited.

To alter these settings, within the POV-Ray menu go to '''Tools > Edit resolution INI file''' and the file should then open up as a text file. You should see a number of different resolutions, mainly set to the 4:3 ratio (640x480, 800x600, etc.), along with [http://en.wikipedia.org/wiki/Spatial_anti-aliasing anti-alias] switches. For example:

<pre>[800x600, No AA]
Width=800
Height=600
Antialias=Off</pre>

or

<pre>[800x600, AA 0.3]
Width=800
Height=600
Antialias=On
Antialias_Threshold=0.3</pre>

This rather limits the available ratios, such as 16:9 (widescreen) or 2.35:1 (anamorphic widescreen). Therefore you need to specify your own. To make it easier to pick out which aspect ratio I need, I often specify this in the preset, as in the below example:

<pre>[800x340 2.35:1, No AA]
Width=800
Height=340
Antialias=Off

[800x450 16:9, No AA]
Width=800
Height=450
Antialias=Off</pre>

You can also specify further sizes by adding variations on the above, and add anti-aliasing to each resolution by changing '''Antialias=Off''' to:

<pre>Antialias=On
Antialias_Threshold=0.3</pre>

===Custom inserts===
POV-Ray includes the option to insert pre-defined parameters into a POV-Ray file, either from the main menu ('''Insert''') or by right-clicking the Editor window.

The purpose of setting these up for rendering LDraw models is to make it easier to insert often-used options, such as radiosity settings or HDRI lighting environments. By default, POV-Ray will store the "Inserts" folder here:

<pre>C:\Users\%USERNAME%\Documents\POV-Ray\v3.7\Insert Menu</pre>

#if (LDXFloor != 0)

}
#end</pre>

The '''Floor settings''' section automatically changes the floor variables to something I find works better, meaning I don't have to edit each file that LDView exports.

The '''Fog''' section creates a fogging effect in the background, which softens the horizon when the POV-Ray camera is pointing at a shallow angle.

==Setting up the LGEO library==

If you've installed the LGEO library from the AIOI to the default location, then it should be located at '''C:\Program Files\LDraw\LGEO'''.

Although updated by Lutz Uhlmann in 2008, there are still a few errors in the library, some of which are simply compatibility issues with any version of POV-Ray higher than 3.1. Where possible, I have fixed any files that I have come across, as well as create some new files, which can be found in the LGEO Parts Pack listed above.

The file itself mainly contains LGEO files (marked with '''lg_''' at the beginning of the file) which can simply be copied to LGEO's '''C:\Program Files\LDraw\LGEO\lg''' folder.

It also contains a file called '''LGEO.xml''' which must be copied to the LDView installation folder.

==Setting up POV-Ray==

===povray.ini===
To function properly with the LGEO library, POV-Ray needs to be told where to find the library files, and this is done via the '''povray.ini''' file. To edit this, within the POV-Ray menu go to '''Tools > Edit master POVRAY.INI'''. This will open the file as a text file, and give you some basic explanation on how to add or modify settings within this file.

You need to ensure that library paths are included in the file, pointing to the installation folder for LGEO. If using the AIOI, this is installed by default to the '''C:\Program Files\LDraw''' folder, so the following lines would need to be added to the end of the file:

<pre>Library_Path="C:\Program Files\LDraw\LGEO"
Library_Path="C:\Program Files\LDraw\LGEO\ar"
Library_Path="C:\Program Files\LDraw\LGEO\lg"</pre>

If you're using a 64-bit version of Windows, then you may need to change '''Program Files''' to '''Program Files (x86)'''.

===quickres.ini===
POV-Ray includes its own resolution definitions, stored in a file called '''quickres.ini''', which allows you to quickly set your desired image output size. These are accessed via a drop-down box shown at the top left of the POV-Ray window, but the available options are fairly limited.

To alter these settings, within the POV-Ray menu go to '''Tools > Edit resolution INI file''' and the file should then open up as a text file. You should see a number of different resolutions, mainly set to the 4:3 ratio (640x480, 800x600, etc.), along with [http://en.wikipedia.org/wiki/Spatial_anti-aliasing anti-alias] switches. For example:

<pre>[800x600, No AA]
Width=800
Height=600
Antialias=Off</pre>

or

<pre>[800x600, AA 0.3]
Width=800
Height=600
Antialias=On
Antialias_Threshold=0.3</pre>

This rather limits the available ratios, such as 16:9 (widescreen) or 2.35:1 (anamorphic widescreen). Therefore you need to specify your own. To make it easier to pick out which aspect ratio I need, I often specify this in the preset, as in the below example:

<pre>[800x340 2.35:1, No AA]
Width=800
Height=340
Antialias=Off

[800x450 16:9, No AA]
Width=800
Height=450
Antialias=Off</pre>

You can also specify further sizes by adding variations on the above, and add anti-aliasing to each resolution by changing '''Antialias=Off''' to:

<pre>Antialias=On
Antialias_Threshold=0.3</pre>

===Custom inserts===
POV-Ray includes the option to insert pre-defined parameters into a POV-Ray file, either from the main menu ('''Insert''') or by right-clicking the Editor window.

The purpose of setting these up for rendering LDraw models is to make it easier to insert often-used options, such as radiosity settings or HDRI lighting environments. By default, POV-Ray will store the "Inserts" folder here:

<pre>C:\Users\%USERNAME%\Documents\POV-Ray\v3.7\Insert Menu</pre>

'''LGEO''' is a library of LEGO parts modeled by [[POV-Ray]] primitives.

When exporting LDraw parts to POV-Ray format, tools like [[LDView]] can use an [[XML]] file,
usually named <code>LGEO.xml</code>, to substitute dedicated parts by their LGEO implementations. The older tool [[L3P]] uses the two files <code>lg_elements.lst</code> and <code>lg_colors.lst</code> to accomplish much the same thing, as well as to indicate whether to switch over to using Anton Raves' POV-Ray parts instead.

Starting from the original library by Lutz Uhlmann, many people edited and added parts to it.
This sadly has led to a tree of variations, not a single collection.

'''LGEO''' is a library of LEGO parts modeled by [[POV-Ray]] primitives.

When exporting LDraw parts to POV-Ray format, tools like [[LDView]] can use an [[XML]] file,
usually named <code>LGEO.xml</code>, to substitute dedicated parts by their LGEO implementations. The older tool [[L3P]] uses the two files <code>lg_elements.lst</code> and <code>lg_colors.lst</code> to accomplish much the same thing, as well as to indicate whether to switch over to using Anton Raves' POV-Ray parts instead.

Starting from the original library by Lutz Uhlmann, many people edited and added parts to it.
This sadly has led to a tree of variations, not a single collection.

Michael Horvath: update link

The page includes a list to known libraries or collections of '''LEGO parts modeled natively in [[POV-Ray]]'''.

The intent is to stop duplication (where possible or desirable) and allow people to use improved parts in their renders.

'''LGEO''' is a library of LEGO parts modeled by [[POV-Ray]] primitives.

When exporting LDraw parts to POV-Ray format, tools like [[LDView]] can use an [[XML]] file,
usually named <code>LGEO.xml</code>, to substitute dedicated parts by their LGEO implementations. The older tool [[L3P]] uses the two files <code>lg_elements.lst</code> and <code>lg_colors.lst</code> to accomplish much the same thing, as well as to indicate whether to switch over to using Anton Raves' POV-Ray parts instead.

Starting from the original library by Lutz Uhlmann, many people edited and added parts to it.
This sadly has led to a tree of variations, not a single collection.
This tree is shown here:
