The Solar System—Intro to React 360
https://dudusotero.github.io/react-360-front-in-floripa/This is a demo application to present React 360, used for a paper at the Front in Floripa event in 2019.
The application is a 360-degree presentation of our solar system. The project's purpose was to present how simple it is to create components in a 3D perspective using React 360. This project can be used as a basis for classes and institutional presentations and can be evolved to create meditation experiences or an interactive 3D model viewer. For a better visual experience, the viewers should use VR goggles.
