Editing Painter's algorithm (section)

== Variants ==

=== Extended painter's algorithm ===
[[Newell's algorithm]], proposed as the extended algorithm to painter's algorithm, provides a method for cutting cyclical and piercing polygons.<ref name=":0" />

=== Reverse painter's algorithm ===
Another variant of painter's algorithm includes '''reverse painter's algorithm'''. Reverse painter's algorithm paints objects nearest to the viewer first — with the rule that paint must never be applied to parts of the image that are already painted (unless they are partially transparent).  In a computer graphic system, this can be very efficient since it is not necessary to calculate the colors (using lighting, texturing, and such) for parts of a distant scene that are hidden by nearby objects.  However, the reverse algorithm suffers from many of the same problems as the standard version.
