[osg-users] Normal Computation and Double Vertex Removal

[Michele Bosi]

Hello,
I was wondering if a function/class exists that computes the normals
of an osg::Geometry given its VertexArray and PrimitiveSet. I just
implemented such a function (very small) but thought that mayb there
was a more "offical" way to do that.

Also I was wondering if there is a class/function that removes double
vertices from an osg::Geometry since I am working on data extracted
with marching cube which generates a lot of doubled vertices.

Thanks,
Mike
