My bachelor thesis in early 2020 revolved around web and browser based virtual reality experiences, that were made accessible by combining several devices into a single Human Computer Interface (HCI).
You can use two smartphones, a smartphone and a laptop, or theoretically any connected device to control the VR experience and enjoy all degrees of freedom.
Front-end: Vue.js v3, Three.js and WebRTC through PeerJS

JavaScript enhanced scroll-snapping used for sliders/carousels.
The goal is to not repeat myself when implementing simple sliders, but also not use one of the huge libraries out there.
Technologies: TypeScript, ES Modules and Classes
See DemoGitHubExperiment (WIP): Vue.js v3 + Three.js Animation
Scrubbing through a keyframed animation, exploration with WASD/Arrow keys controls, and orbit controls. Interaction and reactivity managed in Vue.js.
