VLFLreadSTL

Introduced first in SolidGeometry 1.0, Creation date: 2012-04-06, Last change: 2025-09-14
reads an ascii STL-File as vertex & facet list
Description
Based on a procedure of 2010-Oct. This procedure was under devlopment since the method [VL,j,j1,j2,j3]=VLcat(VL,NVL) seems to be not effective enough. The final method is now, first to read all vertices as list. Later the 'unique' command is used to generate a complete vertex list and facet list from the original data.

Syntax
[VL,FL,S1,S2,STL,AbC,NL]=VLFLreadSTL(FName,[mag,check])
Input Parameter
FName: | | Filename of the STL-File (ASCII) |
mag: | | magnification factor |
check: | | if true, VLFLcheckmeshlab is called; default is false |
Output Parameter
VL: | | Vertex List |
FL: | | Facet List |
S1: | | solid string |
S2: | | endsolid string |
STL: | | The original facet list that uses no vertex list |
AbC: | | Attribute by Count per facet uint16(n) |
NL: | | Normal vector list |
Examples
Generate a simple block, write it into a file, read it from the file and write it a second time.
