[Radiance-general] spatial scale in .obj file

[bei.xiao at gmail.com]

Hi,
  Does anyone know how to recover the spatial scale in an .obj file?
For example, I have an .obj file of a sphere, without any more
information, can I recover its radius in cm?  Also, is the number in
.obj or .rad file specified in cm? Attached please find the .obj file
of the sphere.

Thank you very much.

Bei
