We present a system for efficiently dressing animated 3D models with feathers. While there have been several works on generating static feathers, few methods can incrementally adjust the feathers when the model is animated. Our system makes several important improvements to achieve the goal. We first propose a simple yet effective algorithm to sample the roots based on the orientation field, as the...
In this paper, we present a new numerical method for advection in fluid simulation. The method is built on the Characteristic Mapping method. Advection is solved via grid mapping function. The mapping function is maintained with higher order accuracy BFECC method and dynamically reset to identity mapping whenever an error criterion is met. Dealing with mapping function in such a way results in a more...
