Hi,
Does anyone know what the spatch or hamapatch file format is?
Basically, I want to convert a mesh2 from Povray into spatch or hamapatch.
I looked at the some of the spt and hmp files, but I can't quite figure it
out.
Thanks!
Richard.

I think that would be quite difficult, as those programs use some type of
bicubic patches, not meshes. Converting a mesh to a bicubic patch can be
a close to impossible problem.

Yes, you are correct. But I managed to partially do it (enough for my
needs). I figured out the spatch format (by trying various samples) and by
making all curves not smooth (equivalent to using the peak tool on all
vertices), I was able to do a partial conversion. The program I wrote to do
the conversion, will make all curves only touch two points (so they are all
straight lines). So I managed to convert it, but without normal and uv
mapping information. I might attempt to write another convertion program to
convert it back to meshes.
