# GroupNode
|
|
|
|
A `GroupNode` is a subclass of `ScenegraphNode` that holds a list of `ScenegraphNode` children. Since . A `GroupNode` can be a child of another `GroupNode` and thus be used to create hierarchical scene graphs.
|
|
|
|
|
|
## Usage
|
|
|
|
Add a moon and a box models to the group.
|
|
```js
|
|
// Add objects to the group
|
|
group.add(moon, box);
|
|
```
|
|
|
|
Add a moon and a box models to the group. Then remove them.
|
|
```js
|
|
// Add objects to the group
|
|
group.add(moon, box);
|
|
// Remove the moon
|
|
group.remove(moon);
|
|
```
|
|
|
|
|
|
## Properties
|
|
|
|
`Model` extends the `ScenegraphNode` class and inherits the transformation matrix properties from that class.

|
|
|
|

|
|
|
