[osg-users] Bump mapping question

[Jon Newell]

Hi  Judie

A rarer than hens teeth content question :)
We just use a standard 24 bit normal maps,  for which we use a few 
different tools,  the least sophisticated or useful of which is the 
Nvidia tool, works but is ugly and output is average.
Xnormal  www.*xnormal*.net  and Crazybump http://www.crazybump.com/ are 
the primary ones, of which crazy bump is outstanding for extracting 
normal maps and displacement maps from images  Xnormal is great for 
extracting normal maps from high rez models. X normal  is free, 
Crazybump is not.

cheers
Jon
