hi! ok i jus wanna ask if anyone knows a way to this rendering problem. suppose we got a set of screen space tiles, eg 4 tiles in an 512x512 window, so each tile is 256x256. we got a set of arbitrary screen space coordinates that are obtained from projecting an AABB. how should we go abt to determine if any portion of the AABB overlaps a certain tile? So we can set this tile(s) for rendering. thx! RC
