Sets v1 and v2 to unit vectors such that v1, v2 and *this are mutually orthogonal.
If the length L of *this is smaller than eps, then v1 and v2 will have magnitude L/eps. As a result, the function delivers a continuous result as *this shrinks in length.
Returns the orthogonal complement of this->GetProjection(b).
That is:
Normalizes the vector in place to unit length, returning the length before normalization.
If the length of the vector is smaller than eps, then the vector is set to vector/eps. The original length of the vector is returned. See also GfNormalize().

Orthogonalize and optionally normalize a set of basis vectors.
This uses an iterative method that is very stable even when the vectors are far from orthogonal (close to colinear). The number of iterations and thus the computation time does increase as the vectors become close to colinear, however. Returns a bool specifying whether the solution converged after a number of iterations. If it did not converge, the returned vectors will be as close as possible to orthogonal within the iteration limit. Colinear vectors will be unaltered, and the method will return false.
