finds and removes doubled vertex entries and shows degenerated facts
Description
After removal of doubled vertices, there can be degenerated facets of type [vi vk vk]. Those degenerated Facet MUST NOT BE REMOVED!

Syntax
[VLN,FLN,n]=VLFLcorrectdoubledvertex(VL,FL,[thr])
Input Parameter
VL: | | Vertex list |
FL: | | Facet list |
thr: | | resolution; default is 1e-12 |
Output Parameter
VLN: | | Shortend certex list with original, not rounded vertex values |
FLN: | | Corrected facet list |
n: | | number of removed vertices |
Examples
A=SGbox([30,30,1]); VLFLcorrectdoubledvertex(A.VL,A.FL,2);
A=SGsample(25); VLFLcorrectdoubledvertex(A.VL,A.FL,1);
A=SGbox([30,20,10])
[B.VL,B.FL]=VLFLerrordoubledvertex(A.VL,A.FL)
[C.VL,C.FL]=VLFLcorrectdoubledvertex(B.VL,B.FL)
