Copy constructor

clear(self)

static create_from_axis_aligned_bounding_box(aabb)

Create an OrientedBoundingBox from a legacy Open3D oriented box.

Parameters

aabb (open3d.t.geometry.AxisAlignedBoundingBox) – AxisAlignedBoundingBox object from which OrientedBoundingBox is created.

Returns

open3d.t.geometry.OrientedBoundingBox

static create_from_points(points, robust=(with default value))

Creates an oriented bounding box using a PCA. Note that this is only an approximation to the minimum oriented bounding box that could be computed for example with O’Rourke’s algorithm (cf. http://cs.smith.edu/~jorourke/Papers/MinVolBox.pdf, https://www.geometrictools.com/Documentation/MinimumVolumeBox.pdf) This is a wrapper for a CPU implementation.

Parameters
• points (open3d.core.Tensor) – A list of points with data type of float32 or float64 (N x 3 tensor, where N must be larger than 3).

• robust (bool, optional) –

If set to true uses a more robust method which works in degenerate cases but introduces noise to the points coordinates. Default value:

False) -> open3d.t.geometry.OrientedBoundingBox Creates an oriented bounding box using a PCA. Note that this is only an approximation to the minimum oriented bounding box that could be computed for example with O’Rourke’s algorithm (cf. http://cs.smith.edu/~jorourke/Papers/MinVolBox.pdf
