N2 - Recently, physically-based models have been used to simulate fractures in solid objects. Due to the finite grid used in this type of simulation, aliasing artifacts occur at fracture edges revealing the structure of the grid. We have developed a method for identifying the fractured edges based on the specific grid structure of the model. We then use arbitrary order Bezier curves to modify the grid structure, concealing it at fracture edges. This results in a more convincing fracture edge.
