Hi,
I want to render billboarded polygons that do not change their size as z-depth changes. I know how to do billboarding and that is not the problem.
I tried transforming my vertices by the inverse of the projection matrix. I figure
inverse§ * vertex = vertex’
P * M * vertex’ = clip_coordinates
but that gives some weird results (of course!).
Anyone see an easy solution to this?
