This might need to go into the beginner section, but I believe this is the place.
I want to create a sphere that exudes light from specific vertices. Some areas dark, and some areas shining light back out.
Here are my thoughts:
Use Nvidia's cg to create specific areas of refraction or reflection
Add various lights around the sphere
What I don't understand:
How to create custom lights (I'm using unity 3D)
-Something with random points of emission
-spot lights with short range and acute spot angle (multiple preferably from one light object)
Finally, what would be the most gpu efficient solution to creating an effect like this?
