ldraw_cliff.html is a standalone HTML/ECMAScript application to generate LDraw models ([[LDR]]) of cliff landscapes.

It runs in a browser.

[[File:ldraw_cliff_html.png|500px]]

And it can generate this kind of model:

== Installation and Running ==

Download the [https://gitlab.com/sylvainls/ldraw_cliff.html/-/archive/master/ldraw_cliff.html-master.zip Zip bundle]. Unpack it wherever you want and open the file ldraw_cliff.html in your favorite (and recent) browser.
Fill the form, click on the “Click Me!” button at the bottom of the page and a link to a downloadable [[LDR]] file will appear.

=== How does it work? ===

The main algorithm randomly builds columns of bricks (and slopes), piling them “down” each others, trying to follow (not to be too far from) the neighbouring bricks. The bricks are chosen according to probabilities that varies with the position (top, middle, or bottom of the wall).

When the algorithm can’t find bricks, that is when a column is too far from its neighbour and no bricks can be found to fill the gap, it uses a 1x1 brick. That results in flat portions and warning messages.

=== Main Parameters ===

The generated “cliff wall” will be exactly “width” studs (one brick-width) wide and, at most, “height” bricks high.

=== Top Line Parameters ===

The algorithm starts with the top line and randomly goes down, adding bricks below. So these parameters define the overall shape of the top line.

If you choose not to vary the depth of the top line, it will be a straight line. Otherwise, it will be fixed on the leftmost and rightmost points but will vary randomly in between to the extent of the “maximum depth variation” parameter.

If you choose not to vary the height of the top line, it will be flat. Otherwise, it will vary randomly, not descending below “maximum height variation” and not varying more than “maximum slope of the top” between two adjacent bricks.

Curving the top line gives it a cubic curve, either advancing (positive value) or receding (negative value).

The offset parameter allows to have an oblique wall. Otherwise, leftmost and rightmost top points are aligned on 0.

The more the top line varies, the more the chances of “difficulties” for the algorithm to find bricks to build the wall.

=== Bumpiness ===

Bumpiness is how far one column can be from its neighbours.

=== Main Colours ===

All the colours are LDraw colour numbers.

The grass colour is the colour of the top plates.

The sand colour is the colour of the baseplates.

The rock colour(s) is a comma-separated list of weighted colours for the rocks. By default, the colours are layered. “72,71” means that the bottom half of the wall will be DBG (72) and the top half will be LBG (71). Adding a weight to the colour number will augment the proportion according to the weight. “72,71:2” means the bottom third (default weight is 1) will be DBG and the top two-thirds will be LBG.

Instead of layering the colours, you can choose to randomly use them (in that case, use a high weight for the main colour and low weights for the accent colours).

=== Climbing Path ===

You can add a climbing path to the cliff. It works by “pushing” back the wall above the path, randomly climbing and randomly turning (turning is mandatory when hitting a side).

The path is made of coloured plates of a fixed or variable width.

=== Pebbles ===

These parameters define how “pebbles” are spread on the ground at the bottom of the wall.

=== Sea ===

Some blue (or other colours) plates can be randomly put in front of the wall (and pebbles) in a sinuous wave.

=== Caves ===

You can choose to dig caves.

Digging a cave means pushing back the wall in a random zone. The borders are “smoothed” so that the cave aren’t too squarish.

You can choose to add plates on the caves’ ground.

=== Plants ===

Flower stems can be added on top of the wall (offset chessboard like). Otherwise, 1x1 plates are randomly added to prevent the top to be too flat.

=== Back Line ===

The sides and top plates are prolonged in the back to give a bit of context.

=== Minifigure ===

To better view the scale, a minifig can be added on top of the cliff or on the beach, or both.

lxf2ldr.html is a standalone HTML/ECMAScript application to convert [[LEGO Digital Designer]] models ([[LXF]]) to LDraw models ([[LDR| LDR/.MPD]]).

It uses LDD’s [[ldraw.xml]] conversion file (up-to-date version included) to convert colours, ids, and positions/rotations. It converts LDD’s groups into LDraw subfiles. It also converts decorations (when possible/available in LDraw). And it converts flexible parts, they are exported as [[LSynth]] commands.

== Installation ==

Download the bundled [https://gitlab.com/sylvainls/lxf2ldr.html/-/archive/master/lxf2ldr.html-master.zip Zip file]. Unpack it wherever you want. Open the file lxf2ldr.html in your favorite (and recent) browser. Then click the browsing files button and, once loaded and converted, links to downloadable MPD files will appear at the bottom.

lxf2ldr is a command line tool to convert [[LEGO Digital Designer]] models ([[LXF]]) to LDraw models ([[LDR| LDR/.MPD]]). A minimal GUI is also available.

It uses LDD’s [[ldraw.xml]] conversion file (up-to-date version included) to convert colours, ids, and positions/rotations. It converts LDD’s groups into LDraw subfiles. It also converts decorations (when possible/available in LDraw). And it converts flexible parts, they are exported as [[LSynth]] commands.

== Requirements ==

lxf2ldr comes only is source form and needs to be compiled.

It uses Qt5 core, QuaZIP and yaml-cpp libraries.

== Alternative Project ==

If you can’t build from the sources, or don’t like or want to, [[lxf2ldr.html]], a sibling project, is made for you.

SLS: Adding my version.

The '''LDraw.xml''' file is the file which governs the transformation of models between LDraw [[part]]s and [[LEGO Digital Designer]]. This file is a user editable [[XML]] file.

As both the LDD part selection and LDraw part selection are growing, the ldraw.xml file shipped with LEGO Digital Designer 2 is merely a template.
The LDraw community attempts to keep track of up-to-date versions of this conversion file.
If you modify this file, please add your new version to the top of the list in the same format.
If you upgrade your file, please move it to the top of the list with a new date.
