Question for camera position

[SCUTykLin]

Hello: I found a curious problem of the camera position. U set the camer position is (-4, -4, 10): https://github.com/tvytlx/render-py/blob/e49a986bb32e97d3e194c2b5f7464f95fe0219af/render/core.py#L325 But I download the obj and visualize the 3D object: Camera locates at the positive z axis. So you should render the back view of the object. But the result you show is the front view.
