MeasVRe: Measurement Tools for Unity VR Applications

An indispensable facility that is often missing in VR applications for studying complex 3D models, is the ability to take measurements. This paper describes a toolkit for Unity VR applications that allows for taking distance, angle, trace, surface area, and bounding box volume measurements by placing markers. We show that markers can be efficiently snapped to a model by ray casting. Moreover, we validated taking distance measurements with our toolkit, by performing an experiment where we measure inter-branch distances of corals. Lastly, the toolkit can save measurements locally or upload them to a logging server.
