1 – GeeXLab 0.2.10 Overview

A new version of GeeXLab is ready. GeeXLab 0.2.10 adds few new things related to shadow mapping and brings some bugfixes. More details in the changelog at the end of the post.

The code samples pack has been updated with new demos:

GeeXLab - caustic demo
Animated caustic demo (Lua_Caustic_Anim/ folder)

GeeXLab - mesh bouncer demo
Mesh bouncer demo (Lua_Bouncer/ folder)

GeeXLab - sound spectrum visualizer demo
Sound spectrum visualizer demo (Lua_Sound_Spectrum_Viz/ folder)



The mesh bouncer and sound spectrum visualizer demos are a contribution of Lumen Digital. The guys at Lumen know their work so if you’re looking for some good Lua code samples, check out their demos. Discover Australia Interactive Floor is an example of application developed by Lumen with GeeXLab (actually Discover Australia has been developed with Hyperion, the ancestor of GeeXLab, back to 2007!):

3 – What is GeeXLab?

GeeXLab is a tool (we can call it a demotool) for quick coding and prototyping of real time 3D scenes. GeeXLab can be seen as a real time 3D scene browser (like Firefox for html scripts). You code your 3D scene in one or several source code files, you load the main scene file in GeeXLab and GeeXLab displays the scene. That’s all. GeeXLab language uses a simple mixture of XML, Lua and/or Python and GLSL. All rendering is done with the OpenGL API. For an overview of GeeXLab, just read this article.

OpenGL, Lua, Python, PhysX
