Most tutorials teach you to do billboarding by doing a negative rotation. But, if I use gluLookAt to transform the Matrix, how do I do billboarding (this includes particle system)

Hi
Checkout this Billboarding tutorial.

There is also a section in the OpenGL Game Programming Book if you have it.

Thanks... I''ve checked the site. So all I have to do is to reset the upper left of the ModelView Matrix then everyting will show up in it''s normal place. Thanks

Oh, can anyone tell me the diffrence of Spherical Billboarding and Cylindrical Billboarding ??
