simple elucidation on billboard

Recommended Posts

Hello... when I''ve started to writing my engine, I made billboards implementation. And without to read book or paper, I made them with a simple call: D3DXMatrixRotationY(&matRotY, xxxx); Now I''ve read that is a "must" make them with a direct view-matrix change... It''s ok? My method is fast as the direct wiev-matrix change? I think that it is true... because in the end, I change billbard view-matrix... What do you think?
