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
Famous quotes containing the word transparency:
““End of tomorrow.
Don’t try to start the car or look deeper
Into the eternal wimpling of the sky: luster
On luster, transparency floated onto the topmost layer
Until the whole thing overflows like a silver
Wedding cake or Christmas tree, in a cascade of tears.””
—John Ashbery (b. 1927)
