Something I'd like to improve is the rendering of the laser when it hits the camera. Currently what is being rendered is the diffuse beam (i.e. the beam light that is scattered by the air.) But when that beam covers the camera, there should be a very bright spot of light at the position of the laser source.
I did a few experiments in daylight, shining a laser at a tree about 330 feet (100m) away.
From this distance, it was just visible to the naked eye. Up close there was a visible spot 2-3" across
Iphone X camera looking back at the laser shows a clear bright light that grows and shrinks as you move in and out of the dot.
So I kind of need something like this in the simulator.
