MorphTarget

A Morph Target (also known as Blend Shape) contains deformation data to apply to existing mesh. Multiple morph targets can be blended together on a mesh. This is useful for effects that are hard to achieve with conventional animation and skinning.

Summary

Properties

defaultWeight	The default weight of the morph target.
name	The name of the morph target.
used	A used flag.

Methods

clone

Returns an identical copy of the specified morph target.

Details

Constructor

MorphTarget(options) 

Create a new MorphTarget instance.

Parameters

options	object	Object for passing optional arguments.
options.deltaPositions	ArrayBuffer	An array of 3-dimensional vertex position offsets.
options.deltaPositionsType	number	A format to store position offsets inside VertexBuffer. Defaults to TYPE_FLOAT32 if not provided.
options.deltaNormals	ArrayBuffer	An array of 3-dimensional vertex normal offsets.
options.deltaNormalsType	number	A format to store normal offsets inside VertexBuffer. Defaults to TYPE_FLOAT32 if not provided.
options.name	string	Name.
options.aabb	BoundingBox	Bounding box. Will be automatically generated, if undefined.
options.defaultWeight	number	Default blend weight to use for this morph target.
options.preserveData	boolean	When true, the morph target keeps its data passed using the options, allowing the clone operation.

Properties

numberdefaultWeight 

The default weight of the morph target.

stringname 

The name of the morph target.

booleanused 

A used flag. A morph target can be used / owned by the Morph class only one time.

Methods

clone() 

Returns an identical copy of the specified morph target. This can only be used if the morph target was created with options.preserveData set to true.

Returns

MorphTarget

A morph target instance containing the result of the cloning.
