Converting Omega & Phi to XYZ


Recommended Posts

Paul - I moved this out of the "announcements" forum, because that is the only moderated forum here, and is really for announcements rather than questions.  I admit your question doesn't neatly fit in the other categories.


I'm not sure what you are asking.  omega and phi angles from what type of data?


If it's useful there is a detailed description of the surface normals and how they are represented in this post:



The normals for RTI files are calculated from a set of input images with light positions using a couple of different available algorithms.  I'm pretty sure that's not what you want to know, but maybe you could elaborate a bit.
