Hello, Could you tell me what do you mean "define a mapping from vertex numbers to st coordinate"? Could I do like this in the fragment shader?
gl_TexCoord[0].st = vec2(position.x, position.y); gl_FragColor = texture2D(myTexture, gl_TexCoord[0].st); where position is the distorted pixel coordinates. But how to write the vertex shader? Thanks!
