Package uk.ac.starlink.ttools.plot2.paper

Class SortedPaperType3D

java.lang.Object
uk.ac.starlink.ttools.plot2.paper.PaintPaperType
uk.ac.starlink.ttools.plot2.paper.SortedPaperType3D
All Implemented Interfaces:
PaperType, PaperType3D
public class SortedPaperType3D extends PaintPaperType implements PaperType3D
PaintPaperType for 3-dimensional plots. Suitable for output to vector graphics media.

It works by accumulating a list of glyphs to be painted, and when they are all in (all layer drawings have been processed) sorts them by Z-coordinate and paints them in order. I think that's the only way you can do it for vector graphics. It will unavoidably have a large memory footprint and be slow for large numbers of points.
