ExternalTexture

AI-generated Key Takeaways

• ExternalTexture enables displaying external content like videos in Sceneform by using an Android SurfaceTexture and Surface.

• Sceneform automatically manages the OpenGL ES texture and updates; manual updateTexImage() calls are not needed.

• To utilize an ExternalTexture, use Material.setExternalTexture() with a material parameter of type 'samplerExternal'.

• Provides access to the underlying Surface and SurfaceTexture through getSurface() and getSurfaceTexture() methods, respectively.

public class ExternalTexture

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, updateTexImage() is automatically called and should not be called manually.

Call setExternalTexture(String, ExternalTexture) to use an ExternalTexture. The material parameter MUST be of type 'samplerExternal'.
