Sintesi del contesto e degli obiettivi generali del progetto

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.

Lavoro eseguito dall’inizio del progetto fino alla fine del periodo coperto dalla relazione e principali risultati finora ottenuti

The research has made satisfactory progress towards the main objectives and most targets within the set time frame. For some individual tasks, affected by the epidemic in the early stage, the execution time has been adjusted and travels have been rescheduled. All work packages are well executed.
Among all outputs, a review paper focusing on the project's research direction titled "Physics-based fluid simulation in Computer Graphics: Survey, research trends, and challenges" is forthcoming in the prestigious CVM journal, emphasizing the project's relevance to the field. Moreover, the recognition received for one paper, which won the Best Paper Award at the 4th workshop on Next Generation Computer Animation Techniques, AniNex2022 (co-located with CASA 2022), further highlights the project's contributions and impact. Several papers have been published in notable journals, including two papers in CAVW and one paper in C&G, validating the significance of the research findings in the broader context of computer graphics and visualization.
Furthermore, two papers have been accepted and presented at the CASA AniNex 2023 workshop, with recommendations for publication in journals of CAVW and C&G, showcasing the project's international reach and relevance.
In addition, there is one paper that was accepted by the SIGGRAPH Asia Conference, pending for publication.

Progressi oltre lo stato dell’arte e potenziale impatto previsto (incluso l’impatto socioeconomico e le implicazioni sociali più ampie del progetto fino ad ora)

The project's impactful research outcomes have been extensively disseminated, as evidenced by seven published research papers in prestigious international conferences and journals. Open access is promoted through the project's publications and GitHub repository and website, facilitating public engagement. The project's educational impact is evident through generated lecture notes and course materials aiding knowledge transfer.
We engaged in thorough discussions with prominent stakeholders, including NVIDIA, and gained invaluable practical insights from Dr. Min Jiang. This collaboration facilitated the formation of collaborative networks with experts spanning diverse fields, such as Prof. Jan Hofman and Prof. John Chew from the University of Bath, Prof. Marina Gavrilova from Canada, Prof. Jiri Kosina and Prof. Alexandru C. Telea from the Netherlands, and Prof. Xiaojuan Ban from China.
Furthermore, the project played a pivotal role in providing robust support for the fellow's upcoming endeavors. Building upon the foundational work of the project, they are positioned to delve deeper into exploring the potential applications of fluid simulation across interdisciplinary and practical industrial contexts. This encompasses actively pursuing funding opportunities from esteemed sources such as China's National Natural Science Foundation and the UK's EPSRC.
The outcomes of the Multifluid project carry significant potential across various sectors and scientific communities. Our advanced simulation tools will empower engineers and researchers to enhance process design and optimization, leading to increased efficiency and reduced environmental impact. Industries reliant on fluid dynamics, such as oil and gas, chemical processing, and aerospace, will be equipped to make more informed decisions, resulting in cost savings and heightened operational safety.
Moreover, the project's innovative approach and comprehensive results will deepen our understanding of fundamental fluid behaviour, contributing to the advancement of scientific knowledge. This newfound insight could potentially trigger breakthroughs in fields beyond fluid dynamics, as the acquired understanding of complex interactions in natural and engineered systems shines a light on new possibilities.
In summation, the Multifluid project stands to redefine the boundaries of fluid animation, offering tangible benefits across industries and expanding the horizons of scientific comprehension. Its impact is set to endure, resonating in both academic and practical spheres.
