I currently have vertices with position, texture coordinate and normal data. How do I determine the tangent and binormal data for each vertex?
Some easy to read C# code would be very helpful.
Thanks!

You can create a new vertex element array and clone your mesh with the new format.

Your vertices are real time created? or can be created with a DCC tool? Because the XNA content pipeline calculates automatically the models' tangents if the developer wants it.

If not, maybe (but I doubt it) the XNA team has the tangent method accessor set to public.
