is about using the OpenGL Shader Language GLSL with the free and open Python Library Pyglet.

(Hier ist die deutschsprachige Version)

I finally decided to put my GLSL experiments online - as an inspiration to other programmers. Hopefully this will be evolving into an “intermediate level tutorial” for Shader Programming in GLSL.

This is all free and open source - use it at your own risk and have fun with it !

I use the free software tools I found best for me to make graphics applications. I found Pyglet when I was looking for

• Rapid Prototyping for Graphics Applications
• OpenGL Programming with GLSL
• Cross Plattform OpenGL Support (Windows, Linux, perhaps others)
• Easy Installation (preferably USB-Stick portable)

Let us begin:

• Screenshots to whet your appetite and some philosophy
• Installation fast and furious for Linux and Windows
• Example 1 Start with making the OpenGL Pyglet Example Program “graphics.py” interactive (no GLSL here)
• Example 2 adding Tristam Macdonald's Library Shader.py and do Ambient, Diffuse and Phong Lighting in GLSL
• Example 3 adding a nice texturemap, introducing pyglet resources
• Example 4 Bump Map with Specular Highlights
• Example 5 Parallax Mapping with GLSL
• SOON ! Example 6 Vertex Offset Shader for Deformable Objects
• Example 7 Anisotropic Specular Highlights for Hair with GLSL (hair, brushed metal, silk)
• Example 8 Environmental Bump Mapping with GLSL Cube Mapping
• Example 9 Adding the Library VideoCapture.py by Markus Gritsch to map Video from the USB Camera to an object (Windows only at the moment, but working on a Linux port)
• The Grab Bag: useful stuff and tools - Bumpmap Converter, Realtime Shadows
• Frequently Asked Questions: even with answers, growing
