[VEX] Camera Based Point Cloud Occlusion With Variable Radius [Scene] (Patreon)

How to delete points from a camera view using occlusion in a point cloud with variable radius, without instancing actual geometry.

Because of the perspective distortion, it might look like there are overlapping points but I added a planar camera projection preview mode that shows that no point is actually overlapping. 

Based on a question on the Sidefx forum.
