GeeXLab 0.2.6 Released With Gamma Correction Support

GeeXLab logo

GeeXLab‘s second update of the week is available! The main feature of GeeXLab 0.2.6 is the support of gamma correction in render targets (post-processing). What is gamma correction? Wait a bit, a tutorial will be posted in few minutes 😉

GeeXLab 0.2.6 includes the patch (HYP_Texture.Create() in Python) required for running the demos of the Python / PIL tutorial.

GeeXLab 0.2.6:

Two versions are packed in the installer: GeeXLab_Lua and GeeXLab_Python_Lua. The version of GeeXLab with Python support requires the Python 2.6.6 32-bit installer
(or Python 2.7 32-bit installer) even on 64-bit OSes.

The code samples pack is available HERE.

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
