Infinity Crane — Unity Project

Short Description

Infinity Crane is a VR crane prototype originally developed for a university assignment. The project began as a HoloLens 2 prototype (MRTK v2) with a custom CAD crane skeleton modeled in Shapr3D, later ported to Meta Quest 2 & 3.
It supports hand tracking, controller input, and teleport locomotion, includes a palm/hand menu, and an audio system (SFX, ambience, music) controlled via Unity Audio Mixer.
A small menu feature uses the Jokes API.

Parts of the implementation reference:

• Krane YouTube tutorial
• Unity Asset Store - Low Poly Dungeons Lite
