==Additive Transparency== | |||
Take all the transparent colors and add them up. Addition is commutative so the order doesn't matter. | |||

This builds upon additive transparency with two buffers: | |||
1. Accum buffer: weighted average of all premultiplied-alpha RGB colors. | |||
2. Revealage buffer: buffer representing how much of the opaque background is visible through the transparent layers. | |||
