  In this work, we present an integrated geometric framework: "deep- cut" that
enables for the first time a user to geometrically and algorithmically cut,
tear and drill the surface of a skinned model without prior constraints,
layered on top of a custom soft body mesh deformation algorithm. Both layered
algorithms in this frame- work yield real-time results and are amenable for
mobile Virtual Reality, in order to be utilized in a variety of interactive
application scenarios. Our framework dramatically improves real-time user
experience and task performance in VR, without pre-calculated or artificially
designed cuts, tears, drills or surface deformations via predefined rigged
animations, which is the current state-of-the-art in mobile VR. Thus our
framework improves user experience on one hand, on the other hand saves both
time and costs from expensive, manual, labour-intensive design pre-calculation
stages.
