View Full Version : Mapping a high poly model on a billboard

08-18-2003, 12:51 PM

Given a model that needs to be reduced to a billboard and given a billboard model where each face has specific texture coordinate mapping, is it possible to compute a matrix for each billboard face that transforms the high poly model to align with the billboard face plane in texture coordinate space? That way, I can automatically generate abitrary billboards from my 3d models in an offscreen pbuffer. I'm thinking billboards more complex than just the two regular billboard quads perpendicular to each other.

Yes, do a search on "impostors" and "IBR".

see this year's siggraph paper: billboard cloud

Thanks, billboard clouds look exactly like what I need!
