union_object_model_3dunion_object_model_3dUnionObjectModel3dUnionObjectModel3d (Operator)

Name

union_object_model_3dunion_object_model_3dUnionObjectModel3dUnionObjectModel3d — Combine several 3D object models to a new 3D object model.

Signature

Description

union_object_model_3dunion_object_model_3dUnionObjectModel3dUnionObjectModel3dUnionObjectModel3d combines the data of all input models in ObjectModels3DObjectModels3DObjectModels3DObjectModels3DobjectModels3D to a new 3D object model that is returned in UnionObjectModel3DUnionObjectModel3DUnionObjectModel3DUnionObjectModel3DunionObjectModel3D.

Overlapping areas in the 3D object models might cause the potential 2D mapping, polygons, or triangles in the output to be less useful, since they might overlap, too.

The only supported MethodMethodMethodMethodmethod is so far 'points_surface'"points_surface""points_surface""points_surface""points_surface", which combines all points, surfaces and lines into the output UnionObjectModel3DUnionObjectModel3DUnionObjectModel3DUnionObjectModel3DunionObjectModel3D. Extended Attributes are copied if no holes appear, i.e., if they are present in all input object models where the standard attribute they are attached to exists.

Note that if a 3D object model is no longer needed or should be overwritten, the memory has to be freed first by calling the operator clear_object_model_3dclear_object_model_3dClearObjectModel3dClearObjectModel3dClearObjectModel3d.

Attention

union_object_model_3dunion_object_model_3dUnionObjectModel3dUnionObjectModel3dUnionObjectModel3d ignores 3D object models of type 3D primitive and 3D shape model.

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.

Parameters

Example (HDevelop)

gen_object_model_3d_from_points ([0,0,0,0],[1,1,0,0], [0,1,1,0],\
                                    ObjectModel3D1)
gen_object_model_3d_from_points ([1,1,1,1],[1,1,0,0], [0,1,1,0],\
                                    ObjectModel3D2)
get_object_model_3d_params (ObjectModel3D1, 'diameter', DiameterOld)
union_object_model_3d ([ObjectModel3D1,ObjectModel3D2], 'points_surface',\
                       UnionObjectModel3D)
get_object_model_3d_params (UnionObjectModel3D, 'diameter', DiameterNew)

Result

union_object_model_3dunion_object_model_3dUnionObjectModel3dUnionObjectModel3dUnionObjectModel3d returns 2 (H_MSG_TRUE) if all parameters are correct. If there is no attribute common in all input objects, an exception is raised.
