Calculate the vectors of a camera pointing to an element.

Args:

elem_placement: Placement matrix of an element.

Returns:

Camera position, direction and up vectors

bcf.geometry.camera_vectors_from_target_position(target_position: numpy.typing.NDArray[numpy.float_], offset: numpy.typing.NDArray[numpy.float_] | None = None) → tuple[numpy.typing.NDArray[numpy.float_], numpy.typing.NDArray[numpy.float_], numpy.typing.NDArray[numpy.float_]]

Calculate the vectors of a camera pointing to a target point.

Args:

target_position: point the camera is pointing to. camera_offset: offset of the camera from the target point.

Returns:

Camera position, direction and up vectors

bcf.geometry.unit_vector(v: numpy.typing.NDArray[numpy.float_]) → numpy.typing.NDArray[numpy.float_]

Return the unit vector of a vector.

Args:

v: vector

Returns:

unit vector.
