ShapeKey Class Reference

## Detailed Description

A ShapeKey represents a special ClusterProperty which is used to store a specific geometry. ShapeKeys provide information about how the shape of a cluster changes by either storing its absolute value, an offset based on the object referential or values base on the local reference frame of vertices.

In the context of a ShapeKey, values returned by ClusterProperty::GetValues are automatically converted to object-based referential, which is not the case for ClusterProperty::GetElements.

You can find out the key's reference mode by getting the value of the KeyType parameter. To convert from one reference mode to the other, use the ConvertShapeReferenceMode command.

Warning:
  The KeyType parameter uses a different set of values from the siShapeReferenceMode enum. For more information, see ShapeAnimation Shape Animation

Because a ShapeKey modifies scene content when instantiated, it is an AnimationSource and as such can be accessed by using AnimationSourceItem::GetSource.

Example:
  This example illustrates how to create a ShapeKey

            using namespace XSI;
            Application app;
            Model root = app.GetActiveSceneRoot();

            X3DObject myCube;
            root.AddGeometry( L"Cube", L"MeshSurface", L"", myCube );

            // Creating the first animation source
            CValueArray args(3);
            CValue      outArg;
            args[0] = myCube;
            args[1] = L"myShapeKey";
            args[2] = (LONG)siShapeAbsoluteReferenceMode;
            app.ExecuteCommand( L"StoreShapeKey", args, outArg );

            ShapeKey myShapeKey(outArg);
            app.LogMessage(L"ShapeKey " + myShapeKey.GetFullName());

## Constructor & Destructor Documentation

ShapeKey | ( |  | ) |

Default constructor.

~ShapeKey | ( |  | ) |

Default destructor.

ShapeKey | ( | const CRef & | in_ref | ) |

Constructor.

Parameters:

  in_ref | constant reference object.

ShapeKey | ( | const ShapeKey & | in_obj | ) |

Copy constructor.

Parameters:

  in_obj | constant class object.

## Member Function Documentation

bool IsA | ( | siClassID | in_ClassID | ) | const`[virtual]`

Returns true if a given class type is compatible with this API class.

Parameters:

  in_ClassID | class type.

Returns:
  true if the class is compatible, false otherwise.

Reimplemented from ClusterProperty.

siClassID GetClassID | ( |  | ) | const`[virtual]`

Returns the type of the API class.

Returns:
  The class type.

Reimplemented from ClusterProperty.

ShapeKey& operator= | ( | const ShapeKey & | in_obj | ) |

Creates an object from another object. The newly created object is set to empty if the input object is not compatible.

Parameters:

  in_obj | constant class object.

Returns:
  The new ShapeKey object.

ShapeKey& operator= | ( | const CRef & | in_ref | ) |

Creates an object from a reference object. The newly created object is set to empty if the input reference object is not compatible.

Parameters:

  in_ref | constant class object.

Returns:
  The new ShapeKey object.

Reimplemented from ClusterProperty.

CString GetShapeGroupName | ( |  | ) | const

Returns the name of the shape group to which the shape key object belongs. Shape groups are a way to semantically organize shape keys within a given cluster. This organization is visible within the shape manager view.

Since:
  5.0

CStatus PutShapeGroupName | ( | const CString & | in_shapeGroupName | ) |

Sets the name of the shape group to which the shape key object belongs. Shape groups are a way to semantically organize shape keys within a given cluster. This organization is visible within the shape manager view.

Note:
  If you attempt to assign a non-existing shape group name to a shape key, a new shape group will be created.

Parameters:

  in_shapeGroupName | name of the shape group to which you want to associate the shape key.

Since:
  5.0
