get_minimal_oriented_bounding_box(self: open3d.cpu.pybind.geometry.Geometry3D, robust: bool = False) → open3d::geometry::OrientedBoundingBox¶

Returns the minimal oriented bounding box for the geometry.

Creates the oriented bounding box with the smallest volume. The algorithm makes use of the fact that at least one edge of the convex hull must be collinear with an edge of the minimum bounding box: for each triangle in the convex hull, calculate the minimal axis aligned box in the frame of that triangle. at the end, return the box with the smallest volume

Parameters: robust (bool) – If set to true uses a more robust method which works in degenerate cases but introduces noise to the points coordinates.
Returns: The oriented bounding box. The bounding box is oriented such that its volume is minimized.
Return type: open3d.geometry.OrientedBoundingBox
