Dynamic paint in the bge, for real time emission map, displacement in real time etc
Simple operation built into each object, so the “Camera Vision Cone” makes everything invisible when not in scene,
So “Cone” 1 and “Larger Cone”-Cone 1
3 levels of model that are set up to change by distance, for each origin,
Like level 1 far = low poly, level 2 = medium, level 3 close = HD
Collision Cone 1 = visible
collision Cone 2 = make invisible
NoteRaster needs subdivision cranked up on 2 spheres to be identical
but it does not matter, it is MUCH faster with raster
