Adaptive tearing of crumpled thin sheets

  • Tearing paper is commonly seen in our daily life. Simulating this effect is an important application of thin sheet deformation. Existing approaches only research the cracking effect on normal flat paper. Our work aims at physically simulating tearing papers that have been crumpled by external forces. To achieve this effect, the crumpling tensor field was used as a guidance to grow the cracking paths using external force in an iterative manner. In each step, a physical measurement field defined over the planar domain of paper was updated. A triangular mesh representing the paper was dynamically restructured. Experiments show that the proposed approach generates realistic paper tearing effect with randomly shaped cracking path and physically-plausible cracking details.
