## Detailed Description

A shape describes the deformation on a set of control points, which is similar to the cluster deformer in Maya.

For example, we can add a shape to a created geometry. And the shape and the geometry have the same topological information but different position of the control points. With varying amounts of influence, the geometry performs a deformation effect.

bool SetBlendShapeChannel | ( | FbxBlendShapeChannel * | pBlendShapeChannel | ) |

Search for all occurrences

Set the blend shape channel that contains this target shape.

Parameters:

  pBlendShapeChannel | Pointer to the blend shape channel to set.

Returns:
  `true` on success, `false` otherwise.

FbxBlendShapeChannel* GetBlendShapeChannel | ( |  | ) | const

Search for all occurrences

Get the blend shape channel that contains this target shape.

Returns:
  a pointer to the blend shape channel if set or NULL.

FbxGeometry* GetBaseGeometry | ( |  | ) |

Search for all occurrences

Get the base geometry of this target shape.

Returns:
  a pointer to the base geometry if set or NULL.

Remarks:
  Since target shape can only connected to its base geometry through blend shape channel and blend shape deformer. So only when this target shape is connected to a blend shape channel, and the blend shape channel is connected to a blend shape deformer, and the blend shape deformer is used on a base geometry, then to get base geometry will success.

int GetControlPointIndicesCount | ( |  | ) | const

Search for all occurrences

Get the length of the arrays of control point indices and weights.

Returns:
  Length of the arrays of control point indices and weights. Returns 0 if no control point indices have been added or the arrays have been reset.

int* GetControlPointIndices | ( |  | ) | const

Search for all occurrences

Get the array of control point indices.

Returns:
  Pointer to the array of control point indices. `NULL` if no control point indices have been added or the array has been reset.

void SetControlPointIndicesCount | ( | int | pCount | ) |

Search for all occurrences

Set the array size for the control point indices.

Parameters:

  pCount | The new count.

void AddControlPointIndex | ( | int | pIndex | ) |

Search for all occurrences

Add a control point index to the control point indices array.

Parameters:

  pIndex | The control point index to add.

void Reset | ( |  | ) |

Search for all occurrences

Restore the shape to its initial state.

Calling this function will clear the following:

- Pointer to blend shape channel.
- Control point indices.

virtual FbxObject& Copy | ( | const FbxObject & | pObject | ) | `[virtual]`

Search for all occurrences

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.

Reimplemented from FbxGeometryBase.

virtual FbxNodeAttribute::EType GetAttributeType | ( |  | ) | const`[protected, virtual]`

Search for all occurrences

Returns the type of node attribute.

Reimplemented from FbxLayerContainer.

virtual FbxStringList GetTypeFlags | ( |  | ) | const`[protected, virtual]`

Search for all occurrences

Reimplemented from FbxObject.
