Class Description

An envelope weight is a specialized kind of ClusterProperty used to store the weights for each point on an envelope.

You can use this class to access the deformer objects that control the shape of the envelope.

bool IsA

)

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.

EnvelopeWeight& operator=

(

const EnvelopeWeight &

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 EnvelopeWeight object.

EnvelopeWeight& 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 EnvelopeWeight object.

Reimplemented from ClusterProperty.

CRefArray GetDeformers

(

)

const

Returns the deformers of the envelope that control the shape of the envelope.

Returns:

Array of references to the X3DObject deformers.

CStatus SetValues	(	const CRef &	in_deformer,
		const LONG *	in_pVertices,
		const float *	in_pValues,
		LONG	in_nVertices
	)

Search for all occurrences

Sets the vertex weight values for a given deformer affecting the underlying envelope. This function sets the values directly on the property and the operation is not undoable.

For large data sets, you can use an offset index to set the values in chunks. The offset is used for indexing into in_pVertices which allows you to optimize the memory allocation required for setting the vertex weight values.

Parameters:

in_deformer	The envelope deformer objects.
in_pVertices	Array of size equal to in_nVertices containing the vertex indices to set.
in_pValues	Array of size equal to in_nVertices containing the weight values.
in_nVertices	Number of vertices in in_pVertices.

Returns:

CStatus::OK Success.

CStatus::InvalidArgument Returns an error if in_nVertices is greater than the number of weights for the specified deformer or smaller than zero. Also returns an error if in_pVertices or in_pValues are invalid.

CStatus SetValues	(	const CRef &	in_deformer,
		const float *	in_pValues,
		LONG	in_nValues,
		LONG	in_nOffset = 0
	)

Search for all occurrences

Sets the vertex weight values for a given deformer affecting the underlying envelope. This function sets the vertex elements in the order specified by in_pValues. Values are set directly on the property and the operation is not undoable.

For large data sets, you can use an offset index to set the values in chunks. The offset is used for indexing into cluster elements which allows you to optimize the memory allocation required for setting the element values.

Parameters:

in_deformer	The envelope deformer objects.
in_pValues	Array of size equal to in_nValues containing the weight values.
in_nValues	Number of values in in_pValues.
in_nOffset	Specifies the starting index in the vertex elements of the cluster.

Returns:

CStatus::OK Success.

CStatus::InvalidArgument Returns an error if in_nVertices is greater than the number of weights for the specified deformer or smaller than zero. Also returns an error if in_pValues is invalid.
