Multi-level Multi-phase Fluid Animation

MultiFluid is designed to stand on the front of fluid computer animation and tackle the most challenging issues of multiphase fluid simulation which addresses the industrial needs of stunning computer animation. Its innovation rests on two supporting pillars in implementation: 1) a coherent multi-level simulation approach framework to provide refinement to the fluid details (resolving the convergence issue in multi-scale particle-based simulation) and offer good controls in animation, 2) a multi-phase interaction and phase-transition model to consider complex physics beyond the state of the art. A collection of Fluid Animation Enhancement Techniques has been implemented respectively. Fluid is fascinating and has attracted great interest from both artists and scientists for centuries. Leonardo da Vinci has pinioned the fluid visualisation 500 years ago when he studied the turbulence flow and nowadays researchers are still developing in-depth knowledge and understanding of fluid dynamics. Fluid animation is a challenging topic which requires merge of knowledge and expertise from both science and art. Production of high-quality images demands skillful technicians and talented artists which associated with high labour cost and long production time (up to 1million Euro per minutes animation in film making). Extensive research was conducted, focusing on a surface detail enhancement multi-scale simulation framework with adaptable multi-scale space and time capabilities. Art effect enhancement was achieved by controlling fluid shape through particle groups and surface curvature, based on the motion skeleton. Additionally, physics modeling was improved using volume-based incompressible diffusion and phase-level multiphase models. Advanced knowledge in underlying theory and numerical computation was acquired, granting a significant advantage over existing simulation methods for multiphase fluids and high-resolution fluid surface simulations in the multi-scale framework. The screen-space rendering visualization scheme was also updated to achieve superior real-time visual effects for the animation generation system. Moreover, a novel algorithm for elastic body interaction with fluids was developed, further enhancing fluid control and animation generation capabilities. These advancements have promising implications for various industries, such as entertainment, gaming, and engineering simulations, offering improved visual fidelity and realistic behaviour in virtual environments.
