# [name]

A class containing useful utility functions for scene manipulation.

## Methods

### [method:Group createMeshesFromInstancedMesh]( [param:InstancedMesh instancedMesh] )

instancedMesh -- The instanced mesh.

Creates a new group object that contains a new mesh for each instance of the given instanced mesh.

### [method:Group createMeshesFromMultiMaterialMesh]( [param:Mesh mesh] )

mesh -- A mesh with multiple materials.

Converts the given multi-material mesh into an instance of [page:Group] holding for each material a separate mesh.

### [method:Group createMultiMaterialObject]( [param:BufferGeometry geometry], [param:Array materials] )

geometry -- The geometry for the set of materials.
materials -- The materials for the object.

Creates a new Group that contains a new mesh for each material defined in materials. Beware that this is not the same as an array of materials which defines multiple materials for 1 mesh.
This is mostly useful for objects that need both a material and a wireframe implementation.
