Animating 3D models
Apr 19th, 2009, 4:22pm  
Quake designed and created the MD2 model format  for its character animations. The format was designed to be read by C++ and uses OpenGL. At http://gui4processing.lagers.org.uk/examples.html you will find an applet that demonstrates how MD2 models can be loaded, rendered and animated using Processing with Java.
...
Hope you enjoy.

That had some serious deformation bugs when running it here. Very fun to look at, but not at all what was expected.

http://seltar.org/sketch.php?pid=6 - a sketch i made long ago, trying to simulate some sort of learning AI .. there is one model who knows a lot of sentences, and the other models learn it when they hear it.. so they exchange sentences each time they bump into eachother... it also uses the MD2 loader, and some animations. Navigate with mouseclick + drag, and W,A,S,D

Surprised that you experienced some serious deformation bugs as I have viewed in both Firefox and IE on different machines without problem - can you be more specific.

I had a look at your 3D animation - nice one . I see you have been using Processing since 2005 and have been doing some good stuff.
I came upon Processing last December and became hooked, I searched the discourse and found nothing on MD2 so I thought it would be nice to create a MD2 model loader and demonstrator in Java as I had already used MD2 models with C++. Not sure what you expected but I am glad you think it was fun.

If anyone else experiences problems viewing the model I would appreciate it if you would post a message here - perhaps with a screen shot. Thanks

Seltar experienced some "serious deformation bugs" when viewing this model.

I had serious problems trying to reproduce the problem until I got access to a nice quad core PC and realised that the distortion occurred at frame rates > 61fps.

Cutting a long story short I found the problem in my code and corrected it. Grin

So if you experienced the same problems and were disappointed then have another look at the corrected version here.
