GeometricPrimitive support for tangents #7

Closed walbourn closed 6 years ago

walbourn commented 8 years ago

Currently GeometricPrimitive only generates vertices with VertexPositionNormalTexture vertices. It should at a minimum support a way of generating and drawing with tangents as those are required for NormalMapEffect.

Another option I'm exploring is to just make NormalMapEffect and PBREffect work without precomputed tangents per this article (and this followup blog post):
