Enhanced 3D Body Visualizer Website

I need a web application that recreates the core experience of https://bodyvisualizer.is.tue.mpg.de and then pushes it further. A visitor must be able to build a “virtual me” by typing in basic stats—height, weight, waist size—plus a richer set of sliders that let them fine-tune bust, hip and leg dimensions.

All body data will be entered manually; no photo upload or scanning for now, so the interface must guide users clearly through each field. In addition to the usual height/weight metrics, I also want inputs for arm length, neck size and shoulder width, and the 3D avatar should morph in real time as every number changes.

Core deliverables
• Responsive website with a smooth, WebGL-powered 3D viewer (Three.js, Babylon.js or a comparable framework)
• Parameter panel with live sliders for bust, hip and leg length plus text fields for all other measurements
• Clean, modern UI that works on desktop and mobile
• Simple option to export or save a snapshot of the finished avatar (PNG is fine)

I’m happy to discuss the tech stack you feel is best, as long as the final result loads quickly and runs in any modern browser. If you have relevant demos or libraries in mind, let’s talk.
