more uv coordinates per vertex - 02/12/12 18:42
Hi,
I'm wondering how it's possible to assign more than one uv coordinate to a vertex? Currently I'm giving every vertex in the vertex buffer one uv coordinate. If I want a vertex to have more than one uv coordinate I would have to create more vertices.
But according to this wikipedia article, uv coordinates are managed per face and not per index: link to Wikipedia
So how can this be done without the need of creating additional vertices?
Thanks for your help!

UV coordinates are applied per face,[3] not per vertex. This means a shared vertex can have different UV coordinates in each of its triangles, so adjacent triangles can be cut apart and positioned on different areas of the texture map.
