Moving from negative to positive...

X Axis runs left to right
Y Axis runs down to up
Z Axis runs away to towards you, the user

Hope that''s what you were asking about.

Hmm, so when changing to D3D coords all I would need to do is change Z values to -Z....

+x screen right

+y screen up
-y screen down

+z towards you (out of screen)
-z away from you (into screen)
