Open Source Projects

Arbitrary Remote Control System (ARCS)

Mockup of two devices using a virtual experience remote control system

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 sigle 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

See DemoGitHub

Scroll-Snap Slider

Demo of Scroll-Snap-Slider

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 DemoGitHub

Experiment (WIP): Vue.js v3 + Three.js Animation

An interactive 3D Environment with scrollable and clickable animations.

Scrubbing through a keyframed animation, exploration with WASD/Arrow keys controls, and orbit controls. Interaction and reactivity managed in Vue.js.

Technologies: Blender, Vue.js v3, Three.js

See DemoGitHub

Experiment: Parametrized Canvas Animations

An interactive 3D Environment with scrollable and clickable animations.

Generate beautiful artworks using some well-defined parameters and a bit of randomness.

Technologies: JS, TWEEN.js

See DemoGitHub
