| This example shows the performance aspect of the LOD feature. This is ported from the original [THREE.js LOD example](https://threejs.org/examples/#webgl_lod) | ||
|
|
||
| The code for this example is straightforward. There is only one strange place which is `<ngt-mesh [disabled]="true"></ngt-mesh>`. `ngt-mesh` is not the same as a mere `THREE.Mesh`, there are a bunch of other things going on to ensure all the props of a Mesh gets passed over in a declarative manner. However, in the case of LOD, Mesh becomes a special case where they're not on the scene as themselves but as LOD's levels. With this in mind, we do not need the extra functionality of `ngt-mesh` and therefore can `[disabled]` the controller underneath of `ngt-mesh`. | ||
|
|
||
| Note that there will be no Events handled when `disabled` is true. | ||
