hi all,
new poster here.
i work on a variety of platforms and have found the need to convert a discrete
number of data sets to stl file format. i have done a decent amount of research
on this but i am afraid it is beyond my technical capacity at the moment.
is there anyone on the forum that may be able to do this for me as a favor or
alternatively to do consult via a skype session to get me set up to do this
myself?
perhaps both?
thanks in advance,
j

Sorry, but there is more than just triangles in Povray: despite the
usual approach of the majority of rendering engine, a sphere in Povray
is not, at any time, transformed as a set of planar faces.
The same hold true for most primitives of Povray, as well as for CSG
operations.
If your Povray scene is made of mesh objects (collection of triangles),
then the adaptation to the stl file format might just be a matter of
massaging the syntax. (but that does not sound easy either)

Hi formpig :)
There is a tessilation-patch of povray
http://jgrimbert.free.fr/pov/patch/tessel/index.html
But you still need to convert the raw-Data to stl.
Stl-files containing information about the specific size of an object. (Inch,
mm, cm..) Povray have its own units, but it doesn't referred to an specific
length.
You will need to use a converter and (best) another application, like Blender,
to import the objects, scale it to its right size and export them as .stl
Ps.: I wasn't able to compile the patch statically under cygwin. If you be able
to solve that problem, I would be very happy for a link to the executable, so
that we be able to use it under windows too.
Good luck!
Holger

Except for mesh/mesh2 objects, all objects in POV-Ray are purely
mathematical entities. A sphere, for example, is an object whose surface
is located at a given radius from a center.
Another difference from most modelers and rendereds that use UV maping,
is that the textures are defined in 3D space and you can see the objects
as been carved out of a texture. UV maping IS supported, but only for a
few objects, like mesh.
Apparently, the stl format use some mesh representation of your objects.

Thanks for reminding me to update that page one day.

You might find the patch (and more) inside a 3.7 sources repository in
both git and mercurial depots:
For git:
https://github.com/LeForgeron/Hgpovray
For mercurial:
https://bitbucket.org/LeForgeron/hgpovray
