Name

convex_hull_object_model_3dT_convex_hull_object_model_3dConvexHullObjectModel3dConvexHullObjectModel3d — Calculate the convex hull of a 3D object model.

Signature

convex_hull_object_model_3d( : : ObjectModel3D : ObjectModel3DConvexHull)

Description

convex_hull_object_model_3dconvex_hull_object_model_3dConvexHullObjectModel3dConvexHullObjectModel3dConvexHullObjectModel3d calculates the convex hull of the 3D object model given in ObjectModel3DObjectModel3DObjectModel3DObjectModel3DobjectModel3D. The operator returns the convex hull as a 3D object model with the handle ObjectModel3DConvexHullObjectModel3DConvexHullObjectModel3DConvexHullObjectModel3DConvexHullobjectModel3DConvexHull.

If one of the dimensions of the input points has no deviation at all, the result will consist of lines and not triangles.

Execution Information

Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Processed without parallelization.

Parameters

ObjectModel3DObjectModel3DObjectModel3DObjectModel3DobjectModel3D (input_control) object_model_3d(-array) → (handle)

Handle of the 3D object model.

ObjectModel3DConvexHullObjectModel3DConvexHullObjectModel3DConvexHullObjectModel3DConvexHullobjectModel3DConvexHull (output_control) object_model_3d(-array) → (handle)

Handle of the 3D object model that describes the convex hull.

Number of elements: ObjectModel3DConvexHull == ObjectModel3D

Example (HDevelop)
