Calculate u,v so that p=ts (t some constant). u,v are both in [0,1), thus multiplying them by the texture bitmap's dimensions will yield the texture coordinates. bitmap polygon base at b spanned out by u, v thus is always a parallellogram in 3D uu (2nd bitmap span v.) u (1st bitmap span vector) (bitmap vector) P y Z (screen vector) b (bitmap base vector) -computer screen origo at (0,0,zs) eye=origo=(0,0,0) X
