Detailed Description

Represents a row-major 3x3 matrix.

There's much confusion about matrix layouts (colum vs. row order). This is always a row-major matrix. Even with the aiProcess_ConvertToLeftHanded flag.

inlinestatic

A function for creating a rotation matrix that rotates a vector called "from" into another vector called "to".

Input : from[3], to[3] which both must be normalized non-zero vectors Output: mtx[3][3] – a 3x3 matrix in colum-major form Authors: Tomas M�ller, John Hughes "Efficiently Building a Matrix to Rotate One Vector to Another" Journal of Graphics Tools, 4(4):1-4, 1999

aiMatrix3x3 & aiMatrix3x3::Inverse ( )

inline

Invert the matrix.

If the matrix is not invertible all elements are set to qnan. Beware, use (f != f) to check whether a float f is qnan.
