Function Documentation

Matrix4x4 makeInverse (  const Matrix4x4 &  in  )

Create a matrix that is the inverse of the matrix passed to it. This assumes the matrix coming in is affine. Code taken from the "Essential Mathematics . ." book. This also appears to ignore the translation on the principle we know what the inverse of THAT is. Returns: Empty matrix if input is non-invertible.

Here is the call graph for this function:
