Triangle mesh tangent space calculation

Tangent space is a useful mathematical tool, it’s the base for efficient per pixel shading and compressed normal maps. In this presentation we discuss properties and design decisions of the free code we developed. More details can be found in the ShaderX4 article chapter 2.2.
