ExternalTexture

java.lang.Object
- com.google.ar.sceneform.rendering.ExternalTexture

```
public class ExternalTexture
extends java.lang.Object
```
Creates an Android SurfaceTexture and Surface that can be displayed by Sceneform. Useful for displaying video, or anything else that can be drawn to a SurfaceTexture.
The getFilamentEngine OpenGL ES texture is automatically created by Sceneform. Also, SurfaceTexture.updateTexImage() is automatically called and should not be called manually.
Call Material.setExternalTexture(String, ExternalTexture) to use an ExternalTexture. The material parameter MUST be of type 'samplerExternal'.
