When compiling it with cygwin, it only complained about the 'if
(!isfinite(tmp))' in vector.cc.  I just commented it out to get it running
and it worked nice although with the sample parameters in the docu, it
generated 'NaN' values in the output.

I doubt these two things are related because the 'if (!isfinite(tmp))'
construction would not even finish the calculation.  

I don't know any C++ so i would appreciate some info about both the 'NaN'
output and the isfinite() function

Have you thought about adding it directly to Povray? that would make it
possible to use all Povray object for collision. 

Another nice thing would be smooth meshes.
