Extends a 3x3 matrix to a Matrix4: the 3x3 in the corner, zero translation, and 1 at _44.
m := make_matrix4(Matrix3_Identity);
assert(m == Matrix4_Identity);make_matrix4 :: (m: $T/interface AnyMatrix3) -> Matrix4m as a 4x4 matrix. The extra row and column are those of the identity.
Parameters
- m: $T/interface AnyMatrix3
- the matrix to copy from.
