		<summary type="html">&lt;p&gt;Created page with &amp;quot;{{Person|Name=Roland Melkert|Username=Roland|Age=34|Country=Netherlands|Roles=LSC}}  Roland is the author of LD4DStudio and LDCad and a current member of the LDraw Standards C...&amp;quot;&lt;/p&gt;
&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;{{Person|Name=Roland Melkert|Username=Roland|Age=34|Country=Netherlands|Roles=LSC}}&lt;br /&gt;
&lt;br /&gt;
Roland is the author of LD4DStudio and LDCad and a current member of the LDraw Standards Committee (LSC).&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Name:&amp;#039;&amp;#039;&amp;#039; Roland Melkert (Username: Roland)&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Age:&amp;#039;&amp;#039;&amp;#039; 34 (as of 2011)&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Location:&amp;#039;&amp;#039;&amp;#039; Dordrecht, The Netherlands, Europe&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Occupation:&amp;#039;&amp;#039;&amp;#039; Self employed Software Engineer.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;History with LDraw:&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
Discovered (stumbled on) LDraw somewhere in 2000/2001. Don&amp;#039;t remember how exactly, but I think it was the result of a sidetrack while doing research for a LEGO Mindstorm presentation at college.&lt;br /&gt;
&lt;br /&gt;
Didn&amp;#039;t start really playing around with LDraw until I needed a subject for some 3D programming experiments. I always like to do something practical while learning something new, so this let to a simple viewer which later became LDModeler (~2002).&lt;br /&gt;
&lt;br /&gt;
Around 2004 I had to get familiar with OpenGL and so again LDRaw was used to make something meaningfull while researching something, this led to LDModeler&amp;#039;s successor LD4DStudio.&lt;br /&gt;
&lt;br /&gt;
In 2010 the &amp;#039;Windows only&amp;#039; area seem to decline, so I decided to do some research into multi platform development. This led to LDCad (also fueled by the fact I had troubles drawing models for  usage in LD4DStudio). LDCad also helped with getting a grasp on multi-core programming and deepened my general 3D graphics and OpenGL experience.&lt;br /&gt;
&lt;br /&gt;
In the future I probably keep using LDraw for experimental programming, still much to research :)&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Related interests:&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
I&amp;#039;ve always been a fan of LEGO pretty much only stopped playing with it as a child to eat and sleep. Lost interest (like many) around puberty, but through LDraw rediscovered it in my twenties.&lt;br /&gt;
&lt;br /&gt;
This affection and being a software engineer makes for a productive combination.&lt;/div&gt;</summary>
