Reversed Projection
Author
Hey,
How do I remove or filter away the reversed projection, when doing projective texturing?
Try modulating your projective texture by an OpenGL spotlight, or use a 1d texture which is white in the direction you would like the projection, and black in the other.

How do I use the 1D texture?
And how do I sample the projected texture (a spot-light) so that I can use it in my fragment shader to light up?
