Here's one I can't think of an easy way around.
Imagine a top down solar system. I have some rotating planets, over which I draw a kind of highlight mask, so I can produce the effect of the sun lighting the side of the planets facing the sun. It looks pretty good, even if I do say so myself!
But I'd like to do the same with some irregular shaped objects, for the sake of argument imagine a cone shape which is rotating, or tumbling. How would apply a a brightness mask without the mask lighting an object drawn underneath it? It's impossible to make a mask for every possible position/rotation of the object.
The only way I can think of doing this is to render the object and highlight to a Render Target then draw the result, but then I get into the performance problems discussed in another post.
Can anyone suggest another way to achieve what I'm thinking of?
I hope I've explained this well enough.
