Also, it consists of a collisionShape that helps detect collisions. It can contain a renderable property on which we can set our 3D assets and material shapes.

Node - an object that contains all the information required to be rendered on the screen.

Scene -where our 3D objects are rendered.

In the previous section, we discussed terms nodes, transformable nodes, and more. We can then set up our nodes on this world position.

The first point of intersection of this imaginary ray of light with the plane surface of the AR scene gives us the world position. Imagine a ray light originating from the tapped point on the screen and going through the camera view of your phone. Hit testing is a way of transforming 2D coordinates from the screen where the user taps into their 3D projection in the AR scene. From handling plane detection and allowing us to set up nodes on the scene (can be zero or more nodes), to performing hit testing, and beyond. Sceneform is a node-based graph that does quite a few things.

Handling gestures and collisions on the transformable nodes.

Setting up plane detection and hit testing to add multiple nodes in an Android AR Application using Kotlin.

Addressing some key terminologies and building blocks of ARCore and Sceneform.

Now that we’ve got a good idea of what Sceneform does for us, let’s define the goals of this article. The Sceneform SDK handles the following things on your behalf: Sceneform is tightly integrated with ARCore and makes it easy for Java and Kotlin developers to build high-quality Android AR Apps. It comes with a plugin that lets you import, preview, and build 3D assets directly from Android Studio. Sceneform is a 3D framework that allows us to render 3D models by using a high-level graphics API.

Sceneform: A Lifeboat for Android Developers They introduced Sceneform in 2018, and the rest is history. 3D content importing and viewing wasn’t possible in Java (or Kotlin) when ARCore was released, forcing developers to use OpenGL (the steep learning curving can give nightmares to anyone) or Unity, which is a pain when it comes to integration with Android components. One of the reasons that ARCore’s adoption took some time was due to its initial dependency on OpenGL for 3D graphics.

Yet, despite being introduced in 2017, it didn’t garner much attention or progress for that matter until recently, when new features such as augmented faces, shared camera and AR elements were added and began to show the true potential of ARCore. From motion tracking to environmental understanding and light estimation, it has most of the bases covered already. A Brief HistoryĪRCore does a lot of things. Google has been pushing ahead with its own platform-ARCore-that enables developers to create AR experiences on Android, iOS, Unity, and more. At the turn of this new decade, if there’s one field that has the potential to completely change our way of interacting with smartphones, it’s augmented reality (AR Glasses: are you reading this?).
