I've got a weird problem with POV-Ray and I/O...
What I do is write a series of floats and vectors to a file to save the
transformation of a sphere. I have a macro which gets called and checks if
the matrix is perpendicular and valid. The file is written after that check.
Nontheless, I get "1.#QNAN" in my file, which of course can't be read. The
problem doesn't appear all the time, seems to be slightly persistent when I
make no scene-changes, but generally, it happens right out of the blue. It's
a single file with which it happens, it runs properly on about 50 other file
(I'm using my Rolling-Script in conjunction with my particle system).
Any idea how to check if POV-Ray writes a QNAN instead of a value? I'm
stumped, because POV-Ray doesn't return warning messages or faults with
divide by zero or such. Why should it write a QNAN then?
Regards,
Tim
