Hi,
thanks for your fast answer. So what is the difference then betweehn the Edge
and the LineIterator? I was trying that one too and was expierencing the same
problems.
I'm trying to read out the edges of triangles. What would be the best way to do
so?
thanks,
greets Andy

The EdgeIterator in its current implementation is a little misnamed, but so far
it has not seen a lot of use so it has not affected anybody: It currently only
handles GL_LINES primitives, everything else is ignored. It would not be too
difficult to add the other primitives, if you want to give it a try take a look
at OSGEdgeIterator.cpp.
Sorry for the confusion
Dirk
