All Implemented Interfaces:

PaperType, PaperType3D

public class PixelStackPaperType3D
extends RgbPaperType3D

Bitmapped 3d PaperType which can render any combination of coloured, opaque and transparent pixels.

At each XY position it stores a list of pixels which have been plotted there. Each element in the list contains Z-coordinate, RGB and alpha values, packed efficiently. When all the glyphs have been painted, the list at each XY position is examined, the pixels in that list are sorted by Z-coordinate, and compositing takes place from front to back.
