Planetaria Baked Lighting #113

Ahhhh, this is so cool.

You can give a Color AnimationCurve to set the colors in 360 degrees (e.g. for Ra's sun rays you could do something like a square curve between white and gray).

You have to raycast against geometry to detect where to generate the light information.

You also have to define an (optional) dropoff function.

Research: flood fill algorithm (similar to Invertigo water level)

Notably, any lights that never move can be batched into a single static light. The only limitation is the light resolution (e.g. you probably don't wan't to exceed 6*4096^2 texture resolution for a single point light, which may be an issue for small lights).

Also notably, the shadows can also be baked in with relative simplicity.

Much of my original commentary was intrigue over a PlanetariaCuculoris (more or less) and light/shadow calculations.
