Abstract

As computer generated special effects play an increasingly integral role in the development of films and other media, simulating granular material continues to be a challenging and resource intensive process. Solutions tend to be pieced together in order to address the complex and different behaviors of granular flow. As such, these solutions tend to be brittle, overly specific, and unnatural. With the introduction of a holistic 3-phase granular simulation, we can now create a reliable and adaptable granular simulation.Our solution improves upon this hybrid solution by addressing the issue of particle flow and correcting interpenetration amongst particles while maintaining the efficiency of the overall simulation. We achieve this by projecting particles onto a 2D manifold and implementing density correction using a quadratic solver. Particle updates are projected back into 3D to spread the particles apart on each frame.Keywords:
