Create a Renderable

A Renderable is a 3D model and consists of vertices, materials, textures, and more. It can be attached to a Node and rendered as part of a scene. This page describes how to create and modify Renderables.

Create from Android widgets

You can create a ViewRenderable from standard android widgets. These are rendered as flat cards in the scene.

To create one:

  1. Create a layout file in res > layout. For example:

    <TextView xmlns:android=""
       android:textAlignment="center" />
  2. Build the ViewRenderable.

        .setView(this, R.layout.test_view)
        .thenAccept(renderable -> testViewRenderable = renderable);

    This version of setView() takes the resource ID of the uninflated layout file. You can also call setView(View) to create a renderable from programmatically created views.

All build() methods in Sceneform return a CompletableFuture. The object is built on a separate thread and the callback function is executed on the main thread.

The size of the renderable is based on the size of the View object. By default, every 250dp for the view becomes 1 meter for the renderable. Use setSizer(ViewSizer) to change how the size of the view is calculated.

Changes to the underlying view affect how the renderable is displayed. Nodes with a view renderable attached will dispatch touch events to the view, so you can, for example respond to a button press.

// update button text when the renderable's node is tapped
Button button = (Button) renderable.getView();
button.setOnClickListener((button) -> button.setText("clicked"));

Create from a 3D asset

Sceneform provides tools and plugins for converting 3D assets files (OBJ, FBX, glTF) to Sceneform binary assets (SFB), which can then be built into a ModelRenderable.

For more information, see Import and Preview 3D Assets.

Create simple shapes at runtime

Simple shapes such as cubes, spheres and cylinders can be created using ShapeFactory and MaterialFactory let your create renderable objects from simple shapes and materials.

Here's how to create a red sphere:

MaterialFactory.makeOpaqueWithColor(this, new Color(
            material -> {
              redSphereRenderable =
                  ShapeFactory.makeSphere(0.1f, new Vector3(0.0f, 0.15f, 0.0f), material); });

Load 3D models at runtime

3D models stored as glTF or glb files can be loaded at runtime without conversion. This greatly improves the flexibility of the models rendered in your application, but the trade-off is the model is read at runtime and does not benefit from the optimization that is done during build time conversion to sfb. Because of this, it is recommended you test your application and 3D models on a wide range of devices and network conditions to make sure your users have a great experience.

In order to use runtime asset loading you need to add the dependency on the assets library in the app/build.gradle:

  dependencies {
     implementation ''

The RenderableSource class handles loading the glTF file and creating a source object for ModelRenderable.Builder that creates the renderable object.

For example, loading a model from the internet looks like this:

 private static final String GLTF_ASSET =

 /* When you build a Renderable, Sceneform loads model and related resources
 * in the background while returning a CompletableFuture.
 * Call thenAccept(), handle(), or check isDone() before calling get().
    .setSource(this, RenderableSource.builder().setSource(
            .setScale(0.5f)  // Scale the original model to 50%.
    .thenAccept(renderable -> duckRenderable = renderable)
        throwable -> {
          Toast toast =
              Toast.makeText(this, "Unable to load renderable " +
              GLTF_ASSET, Toast.LENGTH_LONG);
          toast.setGravity(Gravity.CENTER, 0, 0);
          return null;

Note: In order to access resources remotely, you need to include the Internet permission in your AndroidManifest.xml:

    <manifest …>
      <!-- Needed to load a glTF from the internet. -->
        <uses-permission android:name="android.permission.INTERNET"/>


Modify renderables at runtime

If multiple nodes use the renderable, then changes to that renderable apply to all nodes. To avoid that behavior, call makeCopy() to create a separate renderable instance. Note this also calls makeCopy() on every material in the renderable.

blueSphereRenderable = redSphereRenderable.makeCopy();
                  MaterialFactory.MATERIAL_COLOR, new Color(;
