The edge collapes algorithm I implemented is based on various published articles/papers on edge collapse, there isn't a specific one that is the base, but they are all have a lot of similiarity, basically : 1. compute the connectivity of all the triangles/points/edges for the mesh 2. compute the "cost" of collapsing each edge, sort the edges based on the lowest cost to highest cost. 3. while lowst cost edge < tolerance 4. collapse the lowest cost edge, then recompute the cost of all edges that surround the collapsed edge 5. rebuild osg::Geometry from mesh representation Robert.. _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
