Column i (0-based) of a Matrix4 as a Vector4. Column 3 is the translation. No range check.
m := make_translation_matrix4(xyz(1, 2, 3));
assert(column(m, 3) == xyzw(1, 2, 3, 1));column :: (m: Matrix4, i: int) -> Vector4The ith column of the matrix, counting from 0.
Parameters
- m: Matrix4
- the matrix.
- i: int
- the column index, 0 to 3.
