range ordering of triangular facets [message #39530]

Does anyone have any idea how i can obtain a routine that will range
order a series of triangular facets, such that each triangle can be
rendered to appear on top of predecessing ones, without triangles
appearing out of order? The assumption of course is that no triangles
cross, but they can of course share common pairs of vertices?

Unfortunatley, simple range ordering the facets according to the mean
of the distance to the viewer doesnt always work, particularly for
long triangles. This is annoying when rendering, as some triangles
that should be on top lie underneath, leading to an imperfect image.
This must be the bread and butter of some mathematicians, but it's
certainly got me fooled.

Thanks,
Neil
