| I want to experiment a little with GLSL in BlitzMax, and am currently playing with nvidia's mental mill to create some shaders. i can export those as GLSL, but i have no idea what to do with those. can i use them with bmax? |
| ||
for example, this is the code that's generated. how do i use it in blitzmax?
uniform float flip_normal;
varying vec3 position;
void main()
{
gl_Position = ftransform();
position = (gl_ModelViewMatrix * gl_Vertex).xyz;
if( flip_normal > 0.0 ) {
gl_FrontColor = vec4(1.0);
gl_BackColor = vec4(0.0);
} else {
gl_FrontColor = vec4(0.0);
gl_BackColor = vec4(1.0);
}
}

| You have to look at using OpenGL extensions, ARB libraries and all that, to get access to the shader support. |

| Shaders were promoted from ARB status as of OpenGL 2.0 I think, i.e, they're standard GL functions now. These are some great tutorials on GLSL http://www.lighthouse3d.com/opengl/glsl/index.php?intro |
