Sign of Determinants
The sign determination of determinants of 3 x 3 or 4 x 4 matrices is
the one of the most fundamental computations in the computational
geometry. Consider the 4 x 4 matrix:
The determinant of this matrix is 0.
Now, perturb the bottom right element:
Then, the determinant becomes negative.
The results are
Take a look at code.
