neighborsAngleSurface
by Tim C. Lueth, SG-Lib Toolbox: SolidGeometry 5.6 - VLFL/Surfaces
Introduced first in SolidGeometry 4.0, Creation date: 2017-07-05, Last change: 2025-09-14
returns connected facets with respect to a feature angle
Description
The required parameter NAL,NBL are calculated using TR3neighborsAngle. Since TR3neighborsAngle can be slow, the functions are separated to accelerate the repeatet use of neighborsAngleSurface.
See Also: TR3neighborsAngle
Example Illustration
Syntax
[fa,FCL]=neighborsAngleSurface(NAL,NBL,alpha,fi)
Input Parameter
NAL: | | =TR3neighborsAngle(TR3) |
NBL: | | =neighbors(TR3), also delivered by [NAL,NBL]=TR3neighborsAngle(TR3) |
alpha: | | feature angle |
fi: | | starting facet index (can be several) |
Output Parameter
fa: | | facet index with respect to NAL,NBL of (TR3) |
FCL: | | Facet connection list; optional |
Examples
SG=SGsample(25);
[NAL,NBL]=TR3neighborsAngle(SG); fi=neighborsAngleSurface(NAL,NBL,1,22);
