Class 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 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());

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

(

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

(

)

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

)

Search for all occurrences

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
