Manipulating Vertices

[Mario Marengo]

Hi all,

I'm having trouble finding a way to manipulate vertices and their attributes. After scanning GU_Detail and associated classes, I've noticed that GEO_Primitive is the closest I can get to a GEO_Vertex from any of the G*_Detail member functions... but at that level, all vertex-related members are pure virtual, since they're defined by the actual geo types later on.

What I need to do is:

add vertex attribute to detail
foreach prim in detail
   foreach vertex in prim
      get connected vertices (closure)
      eval/assign attribute based on connected vertices
   end
end

The only part I can't find is the "foreach vertex in prim" bit, the rest I'm fine with.

Thanks.

for( i = 0; i < prim->getVertexCount(); i++ )
    GEO_Vertex &vertex = prim->getVertex(i);

Does that help?

Thanks, I'll give that a try when I get home.

I had seen getVertexCount() defined in GB_Primitive as a pure virtual, and then not actually implemented until GEO_Hull, GEO_Face, etc, so I thought it wouldn't work from a GEO_Primitive... but now I realize we're talking about a pointer not an instance... yeah that should work. I'll give it a go. Thanks!
