i have this texture:
i only want one of those circles to been projected on the scene.
i can offset the projection coordinates to limit it to the lower left circle:
vec2 p = vec2( proj.x*0.333, proj.y*0.5 ); Attenuation *= texture2D( texture, p/proj.w ).r;
question: how do i have to offset the projection coordinates so that the other circles are projected? i guess those are not fixed values, but depend on the projector/fragment distance…
btw: i cannot post topics with firefox anymore, the forums always tell me that “the host from which you are accessing the board is not recognized as a valid host.”
