[GEM-dev] glsl and texture

[chris clepper]

void main()
{
    gl_TexCoord[0] = gl_MultiTexCoord0;
       gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex;

}

uniform sampler2DRect MyTex;

void main (void)
{
 vec4 color = texture2DRect(MyTex, gl_TexCoord[0].st);
 color = color* 0.5;
 gl_FragColor = color;
}

Works on OSX.

Change use sampler2D and texture2D for non-rectangle textures.  Or use
arb_fragment program which is more straightforward and performs better.
