High!
I'm looking for a vector graphics program (for Windows or Linux) which
is able to export polygons and curves,
especially Bezier curves, as splines to PoV-Ray. The program should also
support import of bitmap graphics, so that I
would be able to manually draw a bezier curve based on a scanned image.
The underlying problem is that I want to raytrace some Arabic and
Chinese calligraphies made by a friend and, up to
now, found heightfields made out of the (slighly blurred for smooth
edges) scanned originals quite dissatisfactory, they
look to "pixely"...

DXF -> POV http://autocad2pov.povray.co.uk/
I'm sure there are free CAD-like applications with DXF creation over bitmap.

Are you aware of eps2pov? It has been posted to povray.binaries.utilities
by Ross Martin (http://news.povray.org/povray.binaries.utilities/30771/).
So, you can use your favorite vector graphics program and export the image
as postscript. (I suggest XFig http://www.xfig.org/ , if you're looking for
a favorite vector graphics program.)
Greetings

Hi, "CYCAS" is a CAD progran tha exports to POV (the "public" version is
free, I think) Also, Rhino3d (3d modeler, not free) will export nurbs
data as povray meshes.

Open the images with The Gimp. Use for example select by colour to select
the calligraphies. Then selection to path, save the path. You can use my
little Python script gimppath2pov to convert the points of the path to an
array that can be used by POV-Ray as a bezier spline.

This would run only under Linux, wouldn't it? I'm not familiar at all
with Python, if I remember well, it's a purely interpreted language, so I
wouldn't have to compile the script... or am I wrong?

I tried that too. But those meshes are not as good as splines might give
you.
