[Bf-committers] Fwd: Surface from particles (Farsthary)

[Tom M]

The usual method is to use a marching cubes/tetrahedron implementation

http://local.wasp.uwa.edu.au/~pbourke/geometry/polygonise/index.html
http://www.proxyarch.com/util/techpapers/papers/survey%20of%20marching%20cubes.pdf

and here is a marching tiles algorithm used for fluids

Other options are point splattering, carpeting (ie dual carpet quadtree)
