intersect_plane_object_model_3dT_intersect_plane_object_model_3dIntersectPlaneObjectModel3dIntersectPlaneObjectModel3d (Operator)

Name

intersect_plane_object_model_3dT_intersect_plane_object_model_3dIntersectPlaneObjectModel3dIntersectPlaneObjectModel3d — Intersect a 3D object model with a plane.

Signature

Description

intersect_plane_object_model_3dintersect_plane_object_model_3dIntersectPlaneObjectModel3dIntersectPlaneObjectModel3dIntersectPlaneObjectModel3d 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 ObjectModel3DIntersectionObjectModel3DIntersectionObjectModel3DIntersectionObjectModel3DIntersectionobjectModel3DIntersection. 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_3dDispObjectModel3dDispObjectModel3dDispObjectModel3d and queried with get_object_model_3d_paramsget_object_model_3d_paramsGetObjectModel3dParamsGetObjectModel3dParamsGetObjectModel3dParams using the parameter 'lines'"lines""lines""lines""lines".

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_3dIntersectPlaneObjectModel3dIntersectPlaneObjectModel3dIntersectPlaneObjectModel3d returns 2 (H_MSG_TRUE) if all parameters are correct. If necessary, an exception is raised.
