Hi.

im trying to store a tangent for each vertice in my export script so i can use bumpmapping in my game but im having some trouble. Blender provides a method named "mesh.getTangents()". Can anyone here thats familiar with this method from the Blender API help me understand how i need to "convert" what it gives me to what i need.

The API documentation has this to say about the method: "Calculates tangents for this mesh, returning a list of tuples, each with 3 or 4 tangent vectors, these are alligned with the meshes faces."

in the end i need 1 tangent vec3 for each vertice.

I hope i made myself clear.

Thnx in Advance!

EDIT: Now that i think about it, this question might have been better of in "graphics programming and theory". but im not sure since its regarding Blender.
