I wrote Squiggle, a little set of scripts that produces animated 3D views of cave surveys natively in web browsers. Squiggle is based on the javascript library three.js.

Check out this small survey or this cave system (this one might crash browsers on older machines). The controls are as usual: drag for rotating, scroll for zoom. The surveys were made by the Cambridge University Caving Club (CUCC)‘s Austria expeditions, and over time, Squiggle will be used to preview them. Thanks to Wookey for his help in making and testing Squiggle.

Let me know if you would like to use Squiggle to visualise your data.
