intersect_plane_object_model_3dT_intersect_plane_object_model_3dIntersectPlaneObjectModel3dIntersectPlaneObjectModel3dintersect_plane_object_model_3d — Intersect a 3D object model with a plane.

Signature

intersect_plane_object_model_3d( : : ObjectModel3D, Plane : ObjectModel3DIntersection)

Description

intersect_plane_object_model_3dintersect_plane_object_model_3dIntersectPlaneObjectModel3dIntersectPlaneObjectModel3dintersect_plane_object_model_3d intersects a 3D object model with a plane that is defined by the x-y plane of the pose that is specified with the parameter PlanePlanePlaneplaneplane. The z-axis of the pose corresponds to the normal of the plane.

The result is a set of 3D points connected by lines that is returned as 3D object model in ObjectModel3DIntersectionObjectModel3DIntersectionObjectModel3DIntersectionobjectModel3DIntersectionobject_model_3dintersection. Every triangle that intersects with the plane creates two intersection points and a line between the two points. The resulting set of lines is coplanar.

The lines can be displayed with disp_object_model_3ddisp_object_model_3dDispObjectModel3dDispObjectModel3ddisp_object_model_3d and queried with get_object_model_3d_paramsget_object_model_3d_paramsGetObjectModel3dParamsGetObjectModel3dParamsget_object_model_3d_params using the parameter 'lines'"lines""lines""lines""lines".

Parameter Broadcasting

This operator supports parameter broadcasting. This means that each parameter can be given as a tuple of length 1 (7 for PlanePlanePlaneplaneplane) or N (N*7 for PlanePlanePlaneplaneplane). Parameters with tuple length 1 (7 for PlanePlanePlaneplaneplane) will be repeated internally such that the number of computed output models is always N.

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.

Result

intersect_plane_object_model_3dintersect_plane_object_model_3dIntersectPlaneObjectModel3dIntersectPlaneObjectModel3dintersect_plane_object_model_3d returns 2 ( H_MSG_TRUE) if all parameters are correct. If necessary, an exception is raised.
