VLFL/Surfaces - List of features available in SolidGeometry 5.6

delaunayTriangulation2D	returns a 2D delaunay triangulation for planar surfaces in 3D
delaunayTriangulationONE2D	creates a delaunayTriangulation of a single triangle avoiding inaccuracy problems
FLofPLEL	returns tessellation of a 2D points list and contour edge list
neighborsAngleSurface	returns connected facets with respect to a feature angle
PLFLofCPLdelaunayGrid	returns a point list and facet list for a grid filled contour list
PLFLofCPLpshape	returns a delaunay triangulation based on the 2018th concept of polyshape
PLFLofPLalphashape	returns a facet list from a point list using alphashape
PLFLofVLELdelaunay	closes a planar surface of VLEL by delaunay
SGof2facets	creates a surface consisting of two faces
SGseparate	plots or returns sorted surfaces or one surface of a solid geometry
VLFLcat	returns combined solid geometries
VLFLfusedoubledvertices	fuses vertices with similar positions, shortens the VL, but the number of facets remains unchanged.
VLFLspherecurvedPLEL	returns VL and FL for a sphere-curved surface given by a point list and contour edge list
