Abstract:This paper proposes a new data-driven neural network-based fire-flake simulation model. Our model trains a neural network using precomputed fire simulation data. The trained neural network model generates fire flakes in appropriate locations and infers their velocity to make them appear natural to their surroundings. The neural network model consists of a fire-flake generator and a velocity modifier. The fireflake generator uses the velocity, temperature, and density fields of the precomputed fire simulation a… Show more
“…Exploring the Intersection of AI and the Metaverse: As AI technology advances, it is expected to play an increasingly important role in the Metaverse. Future research should explore the intersection of AI and the Metaverse, and investigate how AI can be used to enhance user experiences, create more realistic virtual environments, and support new applications and use cases [36].…”
The Metaverse is all about expanding connectivity amongst users and objects and seamlessly delivering information and services to the right user at the right time. Its potential advantages are virtually limitless, and its applications are progressively changing the way we live, and are opening new opportunities for innovation and growth. It is crystal clear that the Metaverse can enable fully immersive experience, elements of fantasy, and new degrees of freedom. However, it is still considered controversial since it will also open up opportunities for misconduct and crime. Furthermore, the industry lacks the capacity to carry out a comprehensive study of the potential risks that will come along. This paper highlights the current and envisioned Metaverse applications along with the main concerns and challenges faced by the Metaverse stakeholders. Furthermore, it examines the strengths, weakness, opportunities and threats of the Metaverse technology. Finally, the paper presents the future directions and highlights the most important recommendations for developing the Metaverse systems.

In this paper, we propose an artificial neural network framework that can represent the foam effects expressed in liquid simulation in detail without noise. The position and advection of foam particles are calculated using the existing screen projection method, and the noise problem that appears in this process is solved through an proposed artificial neural network. The important thing in the screen projection approach is the projection map, but noise occurs in the projection map in the process of projecting momentum into the discretized screen space, and we efficiently solve this problem by using an artificial neural network-based denoising network. When the foam generating area is selected through the projection map, 2D is inversely transformed into 3D space to generate foam particles. We solve the existing denoising network problem in which small-scaled foam particles disappear. In addition, by integrating the proposed algorithm with the screen-space projection framework, all the advantages of this approach can be accommodated. As a result, it shows through various experiments whether it is possible to stably represent not only the clean foam effects but also the foam particles lost due to the denoising process.
“…Physics-based fluid simulation has been used to realize various visual special effects to simulate water [ 1 , 2 ], fire [ 3 – 5 ], smoke [ 6 – 8 ], fire-flake [ 9 – 11 ], foam [ 12 , 13 ], bubble [ 14 , 15 ], and mist (or spray) [ 16 , 17 ]. When expressing water, the associated secondary effects such as foam, bubble, and splash are caused by oscillating movements, and various approaches have been proposed to efficiently model these characteristics [ 18 , 19 ].…”
This study proposes a neural network framework for modeling the foam effects found in liquid simulation without noise. The position and advection of the foam particles are calculated using the existing screen projection method, and the noise problem that occurs in this process is prevented by using the neural network. A significant problem in the screen projection approach is the noise generated in the projection map during the projecting of momentum onto the discretized screen space. We efficiently solve this problem by utilizing a denoising neural network. Following the selection of the foam generation area using a projection map, the foam particles are generated through the inverse transformation of the 2D space into 3D space. This solves the problem of small-sized foam dissipation that occurs in conventional denoising networks. Furthermore, by integrating the proposed algorithm with the screen-space projection framework, it is able to maintain all the advantages of this approach. In conclusion, the denoising process and clean foam effects enable the proposed network to model the foam effects stably.
