Android Developers: Moving beyond 2D with custom 3D geometry in the Jetpack XR SDK

Transitioning your Android applications from traditional 2D screens into spatial environments requires a new approach to constructing shapes.



In this session, we will explore the Custom Mesh API in the Jetpack XR SDK, which allows you to programmatically generate procedural 3D geometry directly at runtime. We will walk through the core workflow, from defining vertex layouts to rendering dynamic objects seamlessly within the user's physical space.



By the end of this talk, you will have the practical skills to build interactive, custom 3D geometry completely from code.
