Order-independent Transparency

Order-independent transparency or OIT in computer graphics denotes any technique that can correctly render overlapping semi-transparent objects without having to sort them before they are being rendered.

Candidates for order independent transparency solutions include:

• Storage of samples in an accumulation buffer to be sorted at a later time
• Depth peeling (variant: Dual Depth Peeling)
• Screen door transparency
• stochastic transparency: draw in a higher resolution but discard part of the pixels. Downsampling will then yield transparency.

Systems implementing order independent transparency include:

• The Sega Dreamcast games console included hardware support for automatic OIT.
• jreality though depth peeling
