It's an extra-Stata solution, but I have found GnuPlot,
http://www.gnuplot.info/, to be a powerful, easy-to-use, free graphing
program that is capable of high-quality 3D graphing.

Subject: st: RE: 3 D Diagram
The short answer is that there's very little.
By "structure" here I think you mean -surface-
by Adrian Mander. A web search shows that
many people have hit the same problem. -surface-
is not general enough to do what people expect,
and that is no criticism of the author, as
people here expect quite a lot.
An alternative that comes to mind is -scat3-
from SSC. However, the author wrote
on 15 Sept 2004
===============================================
-scat3- is a port to Stata 8 of a program -gr3-
by Bill Gould which offers crude 3-dimensional
graphics (his words, and mine too). Neither
contours, nor perspective (wireframe) views, are
produced, but projections of 3D scatter plots
on to a plane.
-gr3- was published in STB-2 in 1991 and
revised in STB-12 in 1993. It has been (partially)
broken since Stata 3.1 (although the work-around
for that was not difficult) and it always had
a small but noticeable cosmetic problem of
marginal axis labels and ticks which needed
Stage to be employed for removal. (Stage was
the Stata Techies' Amiable Graph Editor, or
some similar acronym or abbreviation.)
Porting this was a lot of fun, re-discovering
the syntax of Stata 2.1 and wondering how best
to map the clever Gould tricks of 1991 into
mundane version 8 -graph- tricks of 2004.
Be assured that having ported this, I have
no plans to add any major bells or whistles,
but it is there for play if it suits. I
guess that Bill would say the same.
============================================
and I gather that's all still true. In other
words, if it doesn't suit, there are no
special tricks undocumented or extensions
in the pipeline for -scat3-. And "no"
means that.
