Abstract:
This paper presents a real-time method for enacting accurate cutting of thin materials while retaining the
physical accuracy of the underlying deformable material model. Our primary contribution is to offer a flexible
real-time solution that can allow accurate cuts, re-cuts, curved cuts, sectioning (cutting out) on a deformable
FEM model. Further contributions include improved handling of mesh element resizing after cutting for
increasing material stability while balancing such resizing against real-time requirements. In this manner, we
can represent precise cut incision (which may be curved or irregular) by subdividing mesh elements locally (at
the cut point) while negating inappropriate (ill-shaped) elements with real-time level computational overhead
and so avoiding modeling instabilities efficiently. We present the results of our solution that show the accuracy
of the cutting method and illustrate timings for our optimised approach demonstrating its real-time qualities.
