Description
smallest_bounding_box_object_model_3dsmallest_bounding_box_object_model_3dSmallestBoundingBoxObjectModel3dSmallestBoundingBoxObjectModel3dSmallestBoundingBoxObjectModel3dsmallest_bounding_box_object_model_3d calculates the smallest
bounding box around the points of a 3D object model.
The resulting bounding box is described using its coordinate system
(PosePosePosePoseposepose), which is oriented such that the longest side of the
box is aligned with the x-axis, the second longest side is aligned with
the y-axis and the smallest side is aligned with the z-axis.
The lengths of the sides are returned in Length1Length1Length1Length1length1length_1,
Length2Length2Length2Length2length2length_2, and Length3Length3Length3Length3length3length_3, in descending order.
The box can be either axis-aligned or oriented, which can be chosen by the
TypeTypeTypeTypetypetype. The algorithm for 'oriented'"oriented""oriented""oriented""oriented""oriented" is
computationally significantly more costly than the algorithm for
'axis_aligned'"axis_aligned""axis_aligned""axis_aligned""axis_aligned""axis_aligned", and returns only an approximation of the
oriented bounding box. Note that the algorithm for the oriented bounding
box is randomized and can return a different box for each call.
In order to retrieve the corners of the 'axis_aligned'"axis_aligned""axis_aligned""axis_aligned""axis_aligned""axis_aligned" box,
the operator get_object_model_3d_paramsget_object_model_3d_paramsGetObjectModel3dParamsGetObjectModel3dParamsGetObjectModel3dParamsget_object_model_3d_params can be used with the
parameter 'bounding_box1'"bounding_box1""bounding_box1""bounding_box1""bounding_box1""bounding_box1".
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on internal data level.

box and is oriented such
that the x-axis is aligned with the longest
side of the box.
Length1Length1Length1Length1length1length_1 (output_control) number(-array) → HTupleSequence[float]HTupleHtuple (real) (double) (double) (double)
The length of the longest side of the box.
Number of elements:
