Implement Depth Peeling for use within a framebuffer pass.
Note that this implementation is used as a fallback for drivers that don't support floating point textures. Most renderings will use the subclass vtkDualDepthPeelingPass instead.
Render the translucent polygonal geometry of a scene without sorting polygons in the view direction.
This pass expects an initialized depth buffer and color buffer. Initialized buffers means they have been cleared with farest z-value and background color/gradient/transparent color. An opaque pass may have been performed right after the initialization.
The depth peeling algorithm works by rendering the translucent polygonal geometry multiple times (once for each peel). The actually rendering of the translucent polygonal geometry is performed by its delegate TranslucentPass. This delegate is therefore used multiple times.
Its delegate is usually set to a vtkTranslucentPass.
This implementation makes use of textures and is suitable for ES3 For ES3 it must be embedded within a pass that makes use of framebuffers so that the required OpaqueZTexture and OpaqueRGBATexture can be passed from the outer framebuffer pass. For OpenGL ES3 be aware the occlusion ratio test is not supported. The maximum number of peels is used instead so set it to a reasonable value. For many scenes a value of 4 or 5 will work well.
