I have been reading through various documentations of the OBJ (i.e. Wavefront) fileformat, and all mention for the vt tag:
vt u v [w] Texture coordinates, in (u ,v [,w]) coordinates, these will vary between 0 and 1, w is optional and default to 0.
It says that u and v should have values between 0 and 1, which makes sense.
But many OBJ files contain entries like:
vt -13.7390 -7.9255 0.0000
How should I interpret those? Currently, I am simply doing a fmod so that I finally obtain values between 0 and 1. But that doesn't look correct. Applications like meshlab correctly interpret those values.
