DTofPLELz
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - Modeling function
Introduced first in SolidGeometry 1.1, Creation date: 2014-01-14, Last change: 2025-09-14
returns a Delaunay Tetrahedron for a point list and edge list
Description
Work in progress
First experiment to switch from surfaces to tetrahedron representation. In contrast to a solid geometry, a Delaunay Tetrahedron is not only the surface desciption, but the complete solid consist of tetrahedron, which outer (free hull) is the solid geoemetry surface
If a triangle [1 2 3] is extruded using the points [4 5 6]
we get three tetrahedrons [4 1 3 2;6 4 3 2; 6 5 4 2]
We will need several functions of this type:
DTofPLELz (PL,EL,z)
DTofCPLz (CPL,z)
DTofPLFLz
Work was interrrupted on 2014-01-14
