Does anybody have any robust code for calculating the rotation angle of a billboard to face the camera?? All the code I have tried has a problem when zooming in/out where the billboard appears to rotate to side view. Any pointers or help would be appreciated. Thanks

I could be wrong, I am not a super math expert, but I beleive the inverse of your view matrix will give you camera facing polygons, if you use it as your world transform for those vertices.
