Hello, <br><br>In MVertex.h, the document says: <br><br>// the id number of the vertex (this number is unique and is<br>// guaranteed never to change once a mesh has been generated)<br> <br> int _num;<br><br>and in the same class MVertex there is function<br>
<br>setNum(int num )<br><br>which allows changing the _num value.<br><br>In fact, in surface meshing, setNum has been used and therefore IDs are modified. There are many<br>situations where this modification creates big problems. Can we stick to the first rule that _num will<br>
never be modified and any use of local numbering may be done by index ( in the MVertex.h ) class.<br><br> <br>csv<br><br>
