## ModelRegistry class

Manages model data for all known models of the game.

**Signature:**

```typescript
export default class ModelRegistry 
```

## Remarks

The ModelRegistry is created internally as a global singletone accessible with the static property `ModelRegistry.instance`<!-- -->.

The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `ModelRegistry` class.

## Example


```typescript
import { ModelRegistry } from 'hytopia';

const modelRegistry = ModelRegistry.instance;
const boundingBox = modelRegistry.getBoundingBox('models/player.gltf');
```
