Detailed Description

Class for blend shape deformer.

A blend shape deformer takes a base shape (polygonal surface, curve, or surface) and blends it with other target shapes based on weight values. Blend shape deformer organize all target shapes via blend shape channel. One blend shape deformer can contains multiple blend shape channels, then each channel can organize multiple target shapes,

See also:

FbxBlendShapeChannel, FbxShape.

Remarks:

The blend effect of each blend shape channel is additive, so the final blend effect of a blend shape deformer is the sum of blend effect of all blend shape channels it contains, the blend effect of each blend shape channel is controlled by the property DeformPercent of blend shape channel.

pGeometry

)

Search for all occurrences

Set the geometry affected by this blend shape deformer.

Parameters:

pGeometry

Pointer to the geometry object to set.

Returns:

true on success, false otherwise.

Remarks:

One blend shape deformer can only be used on one base geometry. So when SetGeometry is called, the pGeometry will replace the current base geometry connected to this blend shape deformer.

FbxGeometry* GetGeometry

(

)

Search for all occurrences

Get the geometry affected by this blend shape deformer.

Returns:

A pointer to the geometry if it is set or NULL if not set yet.

bool AddBlendShapeChannel

(

FbxBlendShapeChannel *

pBlendShapeChannel

)

Search for all occurrences

Add a blend shape channel.

Parameters:

pBlendShapeChannel

Pointer to the blend shape channel object to add.

Returns:

true on success, false otherwise.

Examples:

ExportScene02/main.cxx, and ExportScene03/main.cxx.

FbxBlendShapeChannel* RemoveBlendShapeChannel

Remove the given blend shape.

Parameters:

pBlendShapeChannel

Pointer to the blend shape channel to remove from this blend shape deformer.

Returns:

Pointer to the blend shape channel or NULL if pBlendShapeChannel is not owned by this blend shape deformer.

int GetBlendShapeChannelCount

(

)

const

Get the number of blend shape channels.

Returns:

Number of blend shape channels that have been added to this object.

Get blend shape channel at given index.

Parameters:

pIndex

Index of the blend shape channel.

Returns:

Pointer to the blend shape channel or NULL if index is out of range.

Examples:

ImportScene/DisplayAnimation.cxx, ImportScene/DisplayShape.cxx, and ViewScene/DrawScene.cxx.

Restore the blend shape deformer to the initial state.

Calling this function will do the following:

• Clear the pointer to base geometry.
• Remove all the blend shape channels.

Copy an object content into this object.

Parameters:

pObject

The source object to copy data from.

Returns:

Returns the destination object being modified by the source.

Remarks:

This function replace the assignment operator (operator=). It will copy all property values and the name. Connections are NOT copied.
