In this talk, we'll demystify the workings of AR experiences, from the fundamentals of OpenGL rendering to the pivotal role of ARCore. Discover how AR applications, while seemingly different from traditional virtual experiences, share many underlying principles to any other virtual experience, whether it's a 3D video game or your favorite virtual reality adventure. Through practical demonstrations, you'll gain a comprehensive understanding of computer graphics with OpenGL ES and how to render an AR experience. By the end of the session, you'll walk away equipped with the knowledge to build your own AR apps using Android’s native tools: Jetpack Compose and OpenGL.
