3D experiences are cool, but they can seem a bit tricky, especially for regular web developers. In this talk, Perttu showed that it doesn't have to be hard, both on web and mobile apps. No need to be an experienced developer, the very basics of React will be enough to get started. He presented tools like React Native, ExpoGL, and React Three Fiber used to build these 3D experiences, how to keep things performant, and what you need to consider to keep things working on all platforms.
