Physically-based simulation plays an important role for computer graphics. We can create highly realistic images by simulating optical interaction between light and virtual objects. Realistic animation of complex phenomena can be generated by solving their governing equations such as Navier-Stokes equations for fluids. Many of the existing researches focus on the accurate and efficient simulation of existing physical phenomena. Our research group focuses on a different direction; we 'use' physically-based simulation for different purposes. In this talk, I will introduce some of our research results, including inverse visual simulation of clouds, physically-based aerodynamic sound synthesis, and inverse optical simulation for digital fabrication.
