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. The method uses two trees with different structures. The first tree is a hierarchical grid tree that is easily generatable from the primitive list and modifiable according to its change. The second tree is a … Web22 de abr. de 2024 · This video demonstrates my current progress on ray marching in Unity.
