Mirror Engine API / MorphTarget
Class: 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.
Constructors
new MorphTarget()
new MorphTarget(options: {
aabb: BoundingBox;
defaultWeight: number;
deltaNormals: ArrayBuffer;
deltaPositions: ArrayBuffer;
name: string;
preserveData: boolean;
}, ...args: any): MorphTarget
Create a new MorphTarget instance.
Parameters
options
Object for passing optional arguments.
aabb?
Bounding box. Will be automatically generated, if undefined.
defaultWeight?
number
Default blend weight to use for this morph target.
deltaNormals?
An array of 3-dimensional vertex normal offsets.
deltaPositions
An array of 3-dimensional vertex position offsets.
name?
string
Name.
preserveData?
boolean
When true, the morph target keeps its data passed using the options, allowing the clone operation.
args
...any
Returns
Properties
used
used: boolean = false
A used flag. A morph target can be used / owned by the Morph class only one time.
defaultWeight
Get Signature
get defaultWeight(): number
Gets the default weight of the morph target.
Returns
number
name
Get Signature
get name(): string
Gets the name of the morph target.
Returns
string
Methods
clone()
clone(): MorphTarget
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
A morph target instance containing the result of the cloning.
