transform
Description:
Transforms a Plane this using the
given matrix and normal_matrix.
If normal_matrix is null, a transformation matrix for the plane normal will be computed from
matrix. If you are transforming multiple planes using the same matrix it's recommended to compute the normal matrix
beforehand to avoid incurring in the cost of recomputing it every time.
Parameters:
| this |
a Plane |
| matrix |
a Matrix |
| normal_matrix |
a Matrix |
| res |
the transformed plane |
