# filters.greedyprojection¶

The Greedy Projection filter creates a mesh (triangulation) in an attempt to reconstruct the surface of an area from a collection of points.

GreedyProjectionTriangulation is an implementation of a greedy triangulation algorithm for 3D points based on local 2D projections. It assumes locally smooth surfaces and relatively smooth transitions between areas with different point densities. The algorithm itself is identical to that used in the PCL library.
