class CoordFrame:
    def __init__(self, mat = None):
        if mat is None:
            mat = np.array([1.0,0,0,0],[0,1.0,0,0],[0,0,1.0,0],[0,0,0,1.0])
        self.mat = mat
    def apply(self, vec):
        return self.mat @ vec
    def inverted(self):
        return CoordFrame(self.mat.inverse())

# to move into camera space, call cameraframe.inverted().apply(vector)
# to move into outer space, call innerframe.apply(vector)

next i'll make a class for single-point characters to place in
3-space, to draw the bottom
