Hi Say, > The data is actually rendered in the REVERSE order of passing > to DisplayImpl.addReference() or DisplayImpl.addReferences(). I don't think so. For example, in visad/examples/Test61.java the addReference() for the opaque 2-D texture is called before the addReference() for the transparent 3-D grid, so that the 2-D texture will be rendered first and hence visible. If the 3-D grid were rendered first, it would set Z buffer values less than those of the 2-D texture, and the pixels of the 2-D texture would not be rendered. > Is there anyway of ensuring Text stays on top of lines and > points? This should be possible by passing: ConstantMap(0.1, Display.ZAxis) with the call to addReference() for your Text, to make sure the Text is slightly in front of lines and points.
