WebThe PC-NBV network takes the raw point cloud data and current view selection states as input, and then directly predicts the information gain of all candidate views. By avoiding … WebAug 8, 2024 · If the point cloud is static, you can benefit greatly from employing a spatial index (still on CPU!). You will need to replace the raycast method, as I did with Mesh.raycast here: Octree injection for faster raycasting/raytracing. The principle is that you build the spatial index once, and then use it to accelerate multiple searches afterwards.
