hello,

i changed the fetching.vert shader so that i would be able to
access rgb individually for shifting the vertices,
but the result does not suggest that.

is 
  vec4 color = texture2D(MyTex, gl_MultiTexCoord0.st) 
not a vector with RGBA of a single vertex ?

best

erich


here the shader:

uniform float cr, cg, cb;
uniform sampler2D MyTex;
varying vec4 C;
void main()
{
        vec4 v = vec4(gl_Vertex);
        vec4 color = texture2D(MyTex, gl_MultiTexCoord0.st);
        v.z = color.r*cr + color.g*cg +color.b*cb;      
//      v.x += (color.b-0.5)/2.;
//      v.y += (color.g-0.5)/2.;

        C=color;
        gl_Position = gl_ModelViewProjectionMatrix * v;
        
}
