## What is ThreeTopo?

This version of ThreeTopo contains a single topo for the classic multi-pitch trad climb named "Red Shirt" on Mt. Yamnuska. This application was developed as part of the paper "ThreeTopo: Focused Interactive Navigation for Multi-Pitch Rock Climbing" which was presented at the 2026 ACM CHI Conference on Human Factors in Computing Systems, and was awarded Best Paper. 

We (the authors) have decided to make the application public so that anyone hoping to climb Red Shirt can benefit from the system. We also hope that it may inspire future work on 3D navigation resources for rock climbing.
