WebIn hierarchical ray tracing, on "the way down" you should transform the point and vector forming the ray with a node's inverse transform. On "the way back up" you should transform the intersection point by the original transformation, and (assuming you represent the normal as a column vector) you should transform the normal with the transpose of the upper-3×3 … Web1 de jul. de 2024 · This paper proposes a novel method for accelerating ray tracing of animated scenes in which objects are moved, added, or deleted.
