Virtual Elastic Objects

Abstract

Figure 1. Method overview. We use a multi-view capture system to record objects deforming under the influence of external forces. Our method reconstructs a meshless geometry and deformation field from these sequences. Using a differentiable simulator, we optimize the material parameters of the objects to match the observations. These parameters allow us to find novel, plausible object configurations in response to new forces fields or collision constraints due to user interactions Finally, we re-render the deformed state.
