Ray tracing octree
WebMay 5, 2012 · Here's what it looks like when I stop at the root bounds, without using the DDA to traverse the tree: /* find which leaf, if any, the ray intersects. Returns transparency … WebGiven a pointer-based region octree, intersections of the ray with a node's bisecting planes are first evaluated to determine in which sub-octants the ray-node intersections may lie; a local ordering then determines the sequence in which these sub-octants should be examined so that the intersection closest to the ray's origin can be selected.
