Simulating visual geometry
Matthias Müller, Nuttapong Chentanez, Miles Macklin · 2016
In computer graphics, simulated objects typically have two or three different representations, a visual mesh, a simulation mesh and a collection of convex shapes for collision handling. Using multiple representations requires skilled authoring and complicates object handing at run time. It can also produce visual artifacts such as a mismatch of collision behavior and visual appearance. The reason for using multiple representation has been performance restrictions in real time environments. However, for virtual worlds, we believe that the ultimate goal must be WYSIWYS -- what you see is what you simulate, what you can manipulate, what you can touch.
