Methods and systems for transparent depth sorting are described. In accordance
with one embodiment, multiple depth buffers are utilized to sort depth data associated
with multiple transparent pixels that overlie one another. The sorting of the depth
data enables identification of an individual transparent pixel that lies closest
to an associated opaque pixel. With the closest individual transparent pixel being
identified, the transparency effect of the identified pixel relative to the associated
opaque pixel is computed. If additional overlying transparent pixels remain, a
next closest transparent pixel relative to the opaque pixel is identified and for
the next closest pixel, the transparency effect is computed relative to the transparency
effect that was just computed.
