A matrix whose first three rows are the vectors xprime, yprime, zprime (the rest as in the identity). The type defaults to Matrix4; pass Matrix3 as the last argument for that. Multiplying a point by it takes the point's components along those three directions.
m := make_matrix_from_rows(xyz(0, 1, 0), xyz(1, 0, 0), xyz(0, 0, 1));
assert(m * xyzw(1, 2, 3, 1) == xyzw(2, 1, 3, 1));make_matrix_from_rows :: (
xprime: Vector3,
yprime: Vector3,
zprime: Vector3,
$T := Matrix4
) -> TA matrix whose upper-left 3x3 has the given vectors as its rows. The rest is the identity.
Parameters
- xprime: Vector3
- the first row.
- yprime: Vector3
- the second row.
- zprime: Vector3
- the third row.
- $T := Matrix4
- the matrix type to make.
Returns
- T
