[name]

A mesh that has a [page:Skeleton] with [page:Bone bones] that can then be used to animate the vertices of the geometry. The material must support skinning and have skinning enabled - see [page:MeshStandardMaterial.skinning].

Example


		var geometry = new THREE.CylinderBufferGeometry( 5, 5, 5, 5, 15, 5, 30 );

		// create the skin indices and skin weights

		var position = geometry.attributes.position;

		var vertex = new THREE.Vector3();

		var skinIndices = [];
		var skinWeights = [];

		for ( var i = 0; i < position.count; i ++ ) {

			vertex.fromBufferAttribute( position, i );

			// compute skinIndex and skinWeight based on some configuration data

			var y = ( vertex.y + sizing.halfHeight );

			var skinIndex = Math.floor( y / sizing.segmentHeight );
			var skinWeight = ( y % sizing.segmentHeight ) / sizing.segmentHeight;

			skinIndices.push( skinIndex, skinIndex + 1, 0, 0 );
			skinWeights.push( 1 - skinWeight, skinWeight, 0, 0 );

		}

		geometry.addAttribute( 'skinIndex', new THREE.Uint16BufferAttribute( skinIndices, 4 ) );
		geometry.addAttribute( 'skinWeight', new THREE.Float32BufferAttribute( skinWeights, 4 ) );

		// create skinned mesh and skeleton

		var mesh = new THREE.SkinnedMesh( geometry, material );
		var skeleton = new THREE.Skeleton( bones );

		// see example from THREE.Skeleton

		var rootBone = skeleton.bones[ 0 ];
		mesh.add( rootBone );

		// bind the skeleton to the mesh

		mesh.bind( skeleton );

		// move the bones and manipulate the model

		skeleton.bones[ 0 ].rotation.x = -0.1;
		skeleton.bones[ 1 ].rotation.x = 0.2;

Constructor

[name]( [param:BufferGeometry geometry], [param:Material material] )

[page:Geometry geometry] - an instance of [page:BufferGeometry].
[page:Material material] - (optional) an instance of [page:Material]. Default is a new [page:MeshBasicMaterial].

Properties

See the base [page:Mesh] class for common properties.

[property:string bindMode]

Either "attached" or "detached". "attached" uses the [page:SkinnedMesh.matrixWorld] property for the base transform matrix of the bones. "detached" uses the [page:SkinnedMesh.bindMatrix]. Default is "attached".

[property:Matrix4 bindMatrix]

The base matrix that is used for the bound bone transforms.

[property:Matrix4 bindMatrixInverse]

The base matrix that is used for resetting the bound bone transforms.

[property:Boolean isSkinnedMesh]

Used to check whether this or derived classes are skinned meshes. Default is *true*.

You should not change this, as it used internally for optimisation.

[property:Skeleton skeleton]

[page:Skeleton] representing the bone hierarchy of the skinned mesh.

Methods

See the base [page:Mesh] class for common methods.

[method:null bind]( [param:Skeleton skeleton], [param:Matrix4 bindMatrix] )

[page:Skeleton skeleton] - [page:Skeleton] created from a [page:Bone Bones] tree.
[page:Matrix4 bindMatrix] - [page:Matrix4] that represents the base transform of the skeleton.

Bind a skeleton to the skinned mesh. The bindMatrix gets saved to .bindMatrix property and the .bindMatrixInverse gets calculated.

[method:SkinnedMesh clone]()

Returns a clone of this SkinnedMesh object and any descendants.

[method:null normalizeSkinWeights]()

Normalizes the skin weights.

[method:null pose]()

This method sets the skinned mesh in the rest pose (resets the pose).

[method:null updateMatrixWorld]( [param:Boolean force] )

Updates the [page:Matrix4 MatrixWorld].
