Re: [Opensg-users] HalfEdge example

Thu, 12 Oct 2006 11:07:45 -0700



Hi,

  I am using 1.6 and from the tutorial examples, there isn't one
showing the usage of HalfEdge* classes.

  Is there somewhere I can download an example code using HalfEdge?

  I am interested in representing a polyhedral mesh with HalfEdge so
that I can experiment with edge topology walking and editing.


The OSGHalfEdgeGaph class, which is part of the current 1.x cvs, 
is not useful for editing. Only for creating and walking. There
is no method to removing edges and, AFAIR, it could not be added
easily since the structure is really optimized for efficient
graph-construction from triangle-soups
The class is mainly used to produce strips and fans 
(e.g. with  createOptimizedPrimitives)

best regards,
  johannes

The OSGHalfEdgeGraph class is 
Yours
