Abstract:
We present a new way of adding augmented information based on the computation of the physical equations that truly govern the behavior of objects. In computer graphics, it is common to use big simplifications to be able to solve this type of equations in real time, obtaining in many occasions behaviors that differ remarkably from reality. However, using model order reduction (MOR) techniques we are able to pre-compute a parametric solution that is only evaluated in the visualization stage, greatly reducing the computation time in this on-line phase. We also present several examples that support our method, showing computational fluid dynamics (CFD) examples and deformable solids with nonlinear material behaviors. Since it is a mixed-reality implementation, we decided to create an interactive poster that allows the visualization of augmented reality videos using augmented reality techniques, what we call (AR) 2.
