A school mate working together with me on the project has worked that out.

doing this for general polygons and
handling the edges properly. But that should not be super hard.

What Eric was most probably talking about is the newer versions of
Mayavi, that we tend to call 'mayavi2', even though we are now up to
version 3, in particular the mlab interface:
Dear all,
One of the great advantages of the current mplot3d design is that it
produces complete vector based graphics with the same look-and-feel as
your 2d plots. Integration with OpenGL will certainly change this, as
the rendering will always give you (as far as I know) a bitmap. I
think this

I don't know if creating full blown 3d library makes much sense. I think
Reinier is right here that the current mplot3d creates quite satisfactory

I also agree with Reinier. I want my 3d plots to look as close as possible
to my 2d plots. Because mplot3d uses so much of the same matplotlib core,
this is trivial. As Friedrich mentioned, the mplot3d code is actually pretty
small. To me, that is a great feature. I found the mplot3d
Hi all,
I'll mention again that I intend to continue supporting mplot3d,
although help would be greatly appreciated.
I think the z-ordering issues are in the end quite hard to tackle,
especially since we can have different kinds of structures in a plot,
e.g. polygons and lines (or rather:
I have worked in highschool on a project Beam tracing where I had to
subdivide triangles from a certain point of view with z-ordering and with
such a subdivision how they are covered by the viewing beam. This means
this engine you want to write already exists. See the following ascii
graphics:

We rely on plenty of C++ code so this isn't a problem for us. We would have
to write an interface layer but it shouldn't be too difficult. The harder
problem may be dealing tracking the interior vs the edges of the mesh, but
certainly not

Is it time for some re-thinking of the approach to 3-D? I am a bystander,
but I have the uneasy sense that trying to turn mplot3d into a first-class
3-D plotting tool may be a misapplication of effort. Might the effort be
more productive if applied to

John, your assesment of the problem is correct. And I believe your suggested

Hi,
I have quite general question. Since mplot3d now back in matplotlib, the
question is: is it going to stay there? Or is it some test release? I was just
wondering cause sometimes I use 3d plotting and use Mayavi2 for that but in
many cases it's like killing the spider with a shotgun, not
