void Mul1

(

Matrix4

mat

)

Right Multiply top matrix by an orthonormal matrix 'mat'.

If you know that your matrix is orthonormal, you can use Mul1 instead of Mul. As long as you keep operating on orthonormal matrices, inverse calculations will be faster.

void Set1

(

Matrix4

mat

)

Set an orthonormal matrix.

If you know that your matrix is orthonormal, you can use Set1 instead of Set. As long as you keep operating on orthonormal matrices, inverse calculations will be faster.
