Documentation for how maya compute normals for quads?

AlecMoody

Does anyone have documentation for how maya computes normals for quads? If you aren't familiar with what I am talking about, Maya generates different normal orientations for both force triangulation left/right and quads left triangulated.

the question is a bit vague. maya generates and regenerates normals all the time. when you make a primitive, on import of a file with no normals, after a geometry edit etc. the generation could be different in each case. my grasp of the api is fairly superficial at this point. i would read through the polygon api documentation first. (its fairly detailed)

to be more specific, how maya computes vertex normals for smoothed quads.

Yes, Maya averages different inbetween faces that are quads and faces that are triangles. I believe it averages to the adjacent edges?
