<h2>Methods</h2>
|
||
|
|
|
||
|
|
<h3>[method:Group createMeshesFromInstancedMesh]( [param:InstancedMesh instancedMesh] )</h3>
|
||
|
|
<p>
|
||
|
|
instancedMesh -- The instanced mesh.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
Creates a new group object that contains a new mesh for each instance of the given instanced mesh.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[method:Group createMeshesFromMultiMaterialMesh]( [param:Mesh mesh] )</h3>
|
||
|
|
<p>
|
||
|
|
mesh -- A mesh with multiple materials.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
Converts the given multi-material mesh into an instance of [page:Group] holding for each material a separate mesh.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[method:Group createMultiMaterialObject]( [param:BufferGeometry geometry], [param:Array materials] )</h3>
|
||
|
|
<p>
|
||
|
|
geometry -- The geometry for the set of materials. <br />
|
||
|
|
materials -- The materials for the object.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
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.<br />
|
||
|
|
This is mostly useful for objects that need both a material and a wireframe implementation.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[method:undefined sortInstancedMesh]( [param:InstancedMesh mesh], [param:Function compareFn] )</h3>
|
||
|
|
<p>
|
||
|
|
mesh -- InstancedMesh in which instances will be sorted. <br />
|
||
|
|
compareFn -- Comparator function defining the sort order.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
Sorts the instances within an [page:InstancedMesh], according to a user-defined
|
||
|
|
callback. The callback will be provided with two arguments, <i>indexA</i>
|
||
|
|
and <i>indexB</i>, and must return a numerical value. See
|
||
|
|
[link:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort#description Array.prototype.sort]
|
||
|
|
for more information on sorting callbacks and their return values.
|
||
|
|
</p>
|
||
|
|
<p>
|
||
|
|
Because of the high performance cost, three.js does not sort
|
||
|
|
[page:InstancedMesh] instances automatically. Manually sorting may be
|
||
|
|
helpful to improve display of alpha blended materials (back to front),
|
||
|
|
and to reduce overdraw in opaque materials (front to back).
