FLfeatureEdgeSurface2
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - FS/Feature Surfaces
Introduced first in SolidGeometry 2.1.1, Creation date: 2015-04-08, Last change: 2025-09-14
returns a surface facet list based on a given surface triangulation
Description
In contrast to FLfeatureEdgeSurface, this function also analyzes the final surfaces and separates them into patches (polygon facets) that can be accessed by a patch surface index list.
FLfeatureEdgeSurface analyses the feature edges of a surface, reconnects them into contours, and uses delaunay triangulation on the same points to recalculate the surface. It uses
TRfeatureEdgeFacets
PLELofFeatureEdges2
FLofVLELn
for reconstruction.

Syntax
[NFL,PSIL,CEL]=FLfeatureEdgeSurface2(TR3,angle)
Input Parameter
TR3: | | Surface volume triangulation |
angle: | | filter angle for feature edges |
Output Parameter
NFL: | | Facet List w.r.t TR3.Points |
PSIL: | | Patch Surface Index List. |
CEL: | | Connecting Edge List CEL=[a b VLi VLj], a,b are indices of PSIL |
