Introduced first in SolidGeometry 2.4, Creation date: 2015-08-21, Last change: 2025-09-14

returns the 2D representation for a planar VLFL

Description

This function analyzes generates a HT-Matrix by the first point of the first facet, the ez-vector of the surface, and the longest distance to another point of the facets as ex-axis.

Syntax

[PL,T,c,d]=PLofVLFL(VL,FL,[fi])

Input Parameter

VL: Vertex list [nx3]
FL: Facet list of a planar surface [nx3]
fi: selected indices; default is all

Output Parameter

PL: Point list [nx2]
T: Transformation matrix
c: index list to transform PL indices into VL indices
d: index list to transform VL indices into PL indices

Examples

FL=FLofn(50);
VL=VLtrans(PLcircle(10,50),rotdeg(20,30,40));
PLofVLFL(VL,FL(30:40,:));
[PL,T,c,d]=PLofVLFL(VL,FL(30:40,:));
