tfg.rendering.camera.orthographic.unproject

Unprojects a 2d point in 3d.

tfg.rendering.camera.orthographic.unproject(
    point_2d: type_alias.TensorLike,
    depth: type_alias.TensorLike,
    name: str = 'orthographic_unproject'
) -> tf.Tensor

Unprojects a 2d point \((x', y')\) to a 3d point \((x, y, z)\) given its depth \(z\), with

\[ \begin{matrix} x = x', & y = y', & z = z. \end{matrix} \]

Note
In the following, A1 to An are optional batch dimensions.

Args
point_2d	A tensor of shape [A1, ..., An, 2], where the last dimension represents a 2d point to unproject.
depth	A tensor of shape [A1, ..., An, 1], where the last dimension represents the depth of a 2d point.
name	A name for this op that defaults to "orthographic_unproject".

Returns
A tensor of shape [A1, ..., An, 3], where the last dimension represents a 3d point.

Raises
ValueError	If the shape of point_2d, depth is not supported.
