Computes the 3d ray for a 2d point (the z component of the ray is 1).
tfg.rendering.camera.orthographic.ray( point_2d, name=None )
Computes the 3d ray \((r_x, r_y, 1)\) for a 2d point \((x', y')\) on the image plane. For an orthographic camera the rays are constant over the image plane with
point_2d: A tensor of shape
[A1, ..., An, 2], where the last dimension represents a 2d point.
name: A name for this op that defaults to "orthographic_ray".
A tensor of shape
[A1, ..., An, 3], where the last dimension represents
a 3d ray.
ValueError: If the shape of
point_2dis not supported.
