WebDec 9, 2015 · The purpose of the example Interactive Raycasting Points is to demonstrate that raycasting against THREE.Points works for a variety of geometry types.. So-called "regular geometry", THREE.Geometry, is the least memory-efficient geometry type, and in general, has longer load times than THREE.BufferGeometry. BufferGeometry can be … WebIn static points clouds the primary structures are k-d trees and octrees. Now, because we are using point clouds, the k-d tree using boundary limits reduces to the point cloud k-d tree. Now since we have already discussed octrees independently, we need to explain what a k-d tree is and then focus on the comparing the two for ray casting.
