Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

Vertex Shaders

Note  For testing purposes, you can use a simple pass-through vertex shader:
#version 120
void main(void) {
        gl_Position = ftransform();

Fragment Shaders

Note  To check if your shader is working, add this as the last line, it should turn all pixels black:
gl_FragColor = vec4 (0.0,0.0,0.0,1.0);
