If I was to try and do the following scenario:
Imagine 100 objects floating around the screen. When they intersect, the colour is intensified. Not overly interested in how to achieve the actual effect, but rather the setup.
Would a seperate shader be applied to each object? Would that be completely inefficient? Or would a shader be applied to a single background object that would render the final result?
How would the presence of many objects be able to contribute to the overall result in a shader on a single large object?
Really having trouble thinking this particular scenario through.
