Computes the 3d ray for a 2d point (the z component of the ray is 1).
tfg.rendering.camera.orthographic.ray(
point_2d: type_alias.TensorLike, name: str = 'orthographic_ray'
) -> tf.Tensor
Computes the 3d ray (rx,ry,1) for a 2d point (x′,y′) on the image plane. For an orthographic camera the rays are constant over the image plane with
rx=0,ry=0,z=1.
