Inverts a Matrix4 through its adjugate and determinant, returning (success, result). Fails when abs(determinant) is below epsilon (default 0.0001, an absolute limit), giving the identity as result. Less robust than inverse for badly scaled matrices.
ok, inv := inverse_lengyel(make_scale_matrix4(xyz(2, 4, 8)));
assert(ok && inv._11 == 0.5 && inv._22 == 0.25 && inv._33 == 0.125);inverse_lengyel :: (
m: Matrix4,
epsilon := 0.0001
) -> (success: bool, result: Matrix4)The inverse from the adjugate and determinant. False and the identity when there is none.
Parameters
- m: Matrix4
- the matrix.
- epsilon := 0.0001
- a determinant with a smaller magnitude counts as having no inverse.
Returns
- success: bool
- result: Matrix4
