public class DepthPeelingRenderer3d
extends AWTRenderer3d

Execute depth peeling methods in a Jzy3d Renderer3d This feature is based on Order Independent Transparency algorithms published by Louis Bavoil (NVIDIA Corporation). The renderer support 4 methods:

• Dual depth peeling (accurate)
• Front to back peeling (accurate)
• Weighted average peeling (fast)
• Weighted sum peeling (fast)

Depth peeling is traditionally used to perform order independent transparency (OIT) with N geometry passes for N transparency layers. Dual depth peeling enables peeling N transparency layers in N/2+1 passes, by peeling from the front and the back simultaneously using a min-max depth buffer. This sample performs either normal or dual depth peeling and blends on the fly.
