Create point clouds to navigate cryptic spaces!
We can create and render point clouds using a compute shader, shoot out rays from the camera, both randomly along a disc and a wide area scan. So far it's efficient, functional and fun!
The most interesting tidbits: See this for how the "LiDAR" points are created relative to the player's view, featuring one regular circular scan and one "super scan" that covers the screen. See this file for how some fancy buffers are created to render points efficiently in space using the GPU.
