Tangents for rendering with normal maps

Milef, Nicholas Boris
Hi,

I've trying to add normal mapping to an application (iMSTK). In order to get this to work, we would need tangent vertex attributes. Is this something that could be of interest in VTK?

More generally, it might be useful to allow additional arbitrary vertex attributes in the future for things like GPU skinning, but I'm not sure how well that would work.

Thanks,
Nick
