I've decided to try and enter another car design competition after my forth
place on designerspace.coms 'The Ultimate' competition. So when I heard of
the Go digital competition on http://www.opticore.com/godigital/ I
registered as soon as possible only to discover it needs to be done in one
of the following formwts:

..wire (Alias|Wavefront Studio|Tools)
..3dm (Rhinoceros, version 1.2 or lower)
..iges
..model (CATIA)
..mf1 (IDEAS)
..dxf (Drawing Exchange Format)
..csb (Cosmo Binary)
..pfb (Performer Binary)

Meanwhile I've figured out how to make bezier patches in Pov. So the big
Question is: Is there any way to convert a pov bezier patch to any one of
these formats. Please let me know. I could try modelling it in 3dCanvas but
I'm not sure if it could handel the complexity of a full car. Pov is more
precise as well.

Thanx,

I think using macros Bezier patch can be easily converted to mesh which can be
outputed as dxf since it is a txt format. IIRC there are ready macros for both
purposes.

Thanks.

Does anyone know where I can find these macros?

I once made a macro that generates a mesh for
a bezier patch.

(But I don't know if it is this macro ABX is
referring to.)

If you want to try it, you must look for
the BezierPatchFunction() macro in this post:

http://news.povray.org/povray.text.scene-files/22698/157269/

(This macro is not limited to making functions
for bicubuc patches from a 4x4 grid of points.
It can take any number of control points in
both directions.)

You will also need either one of Ingo's
"Meshmerizing Mesh Maker Macros" or one of my
old mesh macros. (Ingo's macros are nicely
documented. Mine are not.)

You can find Ingo's mesh web page here:

If you want to use my mesh macros, you must
look for WriteParamMesh() or ParametricMesh()
in this post:

Thanks, Tor, I'll take a look at it.
