WebLeast Squares Fitting of a Line and a Plane to a 3D Triangle Set. In the following example we use a STL container of 3D triangles, and compute the best fitting line and plane in the least squares sense. Note that we can fit either the whole triangles, the triangle edges or the triangle vertices. WebFor the Region Growing approach, this package provides three particular shape detection components: detecting lines in a 2D point set, detecting planes in a 3D point set, and detecting planes on a polygon mesh.
