Getting Tangent/Bi-Normal Surface Data

[reepblue]

I'm interested in seeing how I can improve my cyclone placement code and I was wondering if there was a way to obtain the Tangent and Bi-Normal of a surface from a world pick raytrace. The surface class only has the normal vector and the only thing I see regarding this is the vertex class which can be obtained by the surfaces vector array.

This is right now a curiosity than a must have. My placement code works 90% of the time, but I was sharing ideas how this can be improved in a discord channel and this came up.

There is some code here somewhere to calculate the texture coordinate at a picked location. The same code will work to interpolate binormals / tangents.
