So getting a little tired of doing my GUI library (which is still basically useable, just needs touchups) I decied to check out RenderMonkey and learn GLSL.

What a cool tool this is. I was able to create my first shader in no time. Took a little bit to learn exactly how data is passed from RenderMonkey to the shaders but it worked out. RenderMonkey provies quite a collection of variables that it will pass into your shaders.

for my first shader I wanted a simple plane (200 faces or so) to osolate up and down based on time.

Here is my shaders. fTime0_X is a RenderMonkey supplied variable that is the sine of value Time (float).


uniform float fTime0_X;

void main(void)
vec4 pos = gl_Vertex;
pos.z += fTime0_X * 3.0;
gl_Position = gl_ModelViewProjectionMatrix * pos;
//gl_Position = ftransform();


void main(void)
gl_FragColor = vec4( 1.0, 0.0, 0.0, 1.0 );
