Thanks for sharing your script. It's quite sophisticated. Mine is messy :)

For two reasons, I directly use fprintf():

1. The mesh may get large, and surely I will have stack overflow. Thus, I have
to allocate the memory dynamically to keep all the data in memory. The memory
footprint is trivial for the modern machines, but I considered to be safer to
directly write them to the files.

2. When saving the data in raw forms (vectors), I can easily create other mesh
formats from the separate files. It is unlikely, as I only use POV-Ray, but it's
not a bad idea to keep the system flexible for future expansion.
