签名

intersect_plane_object_model_3d( : : ObjectModel3D, Plane : ObjectModel3DIntersection)

描述

intersect_plane_object_model_3dintersect_plane_object_model_3dIntersectPlaneObjectModel3dIntersectPlaneObjectModel3dIntersectPlaneObjectModel3dintersect_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 PlanePlanePlanePlaneplaneplane. 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 ObjectModel3DIntersectionObjectModel3DIntersectionObjectModel3DIntersectionObjectModel3DIntersectionobjectModel3DIntersectionobject_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_3dDispObjectModel3dDispObjectModel3dDispObjectModel3ddisp_object_model_3d and queried with get_object_model_3d_paramsget_object_model_3d_paramsGetObjectModel3dParamsGetObjectModel3dParamsGetObjectModel3dParamsget_object_model_3d_params using the parameter 'lines'"lines""lines""lines""lines""lines".
