[Algorithms] Res: Polygon from point cloud and other from triangle list?

Hmm, really, its a very generic question, I should be more detailed. I have some shapes, grouped together, and would like to create a polygon that represents the resulting shape. Something like a tangram shape, that is formed by smaller shapes. I need to find the outline polygon (may be non-convex, and will be on most of the times) defined by the resulting shape. ----- Mensagem original ---- De: Simon Fenney <sim...@po...> Para: Game Development Algorithms <gda...@li...> Enviadas: Quarta-feira, 24 de Junho de 2009 10:28:23 Assunto: Re: [Algorithms] Polygon from point cloud and other from triangle list?

If none then, AFAICS, given N points you could create (N-1)!/2 different (potentially self-intersecting) polygons.
