Solid procedure to generate facets for ONE closed contour

Description

It is in principle identical to VLFLcloseC but supports also the 3rd dimension to generate a solid based on a height or a displacement vector. For closing objects with an outer and inner contour, used VLFLclose3D2C. The procedure nows supports also concave contours as long as they does not cross itself.

Syntax

[VL,FL]=VLFLclose3DC(VL,[h])

Input Parameter

VL: Vertex list or point list with 4 ore more points
h: optional height or displacement vector; default is 0;

Output Parameter

VL: Vertex list (resorted)
FL: Facet list

Examples

Close a simple square:
PL=[0 0 0; 10 0 0; 10 10 0; 0 10 0];
[VL,FL]=VLFLcloseC (PL,5);
[VL,FL]=VLFLcloseC (PL,[10;10;10]);
VLFplot (VL,FL);
