tfg.geometry.transformation.rotation_matrix_2d.rotate

Rotates a 2d point using a 2d rotation matrix.

tfg.geometry.transformation.rotation_matrix_2d.rotate(
    point,
    matrix,
    name=None
)

Defined in geometry/transformation/rotation_matrix_2d.py.

Note:

In the following, A1 to An are optional batch dimensions, which must be identical.

Args:

  • point: A tensor of shape [A1, ..., An, 2], where the last dimension represents a 2d point.
  • matrix: A tensor of shape [A1, ..., An, 2, 2], where the last two dimensions represent a 2d rotation matrix.
  • name: A name for this op that defaults to "rotation_matrix_2d_rotate".

Returns:

A tensor of shape [A1, ..., An, 2], where the last dimension represents a 2d point.

Raises:

  • ValueError: If the shape of point or matrix is not supported.
