Comparing Convex Region-of-Interest Selection Techniques for Surface Geometry

Selecting 3D regions-of-interest (ROI) in surface geometry is essential for 3D modeling, but few 3D user interfaces using fully manual input for ROI selection exist. Furthermore, their relative performance is not well studied. We present an evaluation comparing three ROI techniques: Volume Cube [Ulinski et al. 2007], Slice-n- Swipe [Bacim et al. 2014], and Yea Big Yea High Selection [Jackson et al. 2018]. Results show that Yea Big Yea High is best for tasks requiring high accuracy and speed, but modifications may be needed for use in dense geometry or with non-convex ROI.
