the field of Artificial Intelligence (AI) has gained increased attention since the release of ChatGPT in late 2022. Following the popularity and wide application, several generative AI (GAI or GenAI) tools have been released, with capabilities of generating novel content such as text, images, audio, and video. Previous research has noted both opportunities and limitations with GAI for various fields. One field with high potential impact is the game industry and the subfield of serious games, where the purpose of the game extends that of pure entertainment. GAI could play an important role for design and development of serious games, where design teams are typically smaller (compared with big commercial games), and competences in game mechanics, graphics and other game resources can be limited. this paper explores the opportunities and limitations of GAI tools to support development of serious games. this is done through the development of a serious game, based on the author’s PhD thesis, where various GAI tools are used to generate game content such as in-game dialogue, graphics, and audio. Development of the game artefact, which is named ‘computer Programming in Schools’, follows the process of a design science research (DSR) project where emphasis is placed on the design in one iteration of development. the author’s experiences of utilizing GAI tools during the development of the game were recorded in a researcher diary, together with screenshots and images from the game. In this paper, these experiences are discussed and compared to related research in order to seek the most salient opportunities and limitations for GAI to support design and development of serious games. the paper provides several hands-on examples of design and development of a serious game with GAI tools and concludes with a set of recommendations for the future use of GAI in game development. © Proceedings of the 4th international conference on AI Research, ICAIR 2024.

this study introduces an innovative human-computer collaboration framework for mining requirements from closed-loop control models in industrial systems. Traditional approaches in this domain face challenges due to vague, non-modular, evolving, or sometimes unknown requirements. Our framework bridges this gap by enabling a synergetic interaction between the user and a computer agent, facilitating the efficient mining of optimal specifications through an interactive interface. We conducted two experimental studies with ten participants to validate our approach. the findings reveal that the integration of human expertise and computational algorithms accelerates the optimization process, thereby aiding designers in achieving satisfactory system designs more rapidly. this research contributes to the field of model-based system design by presenting a novel paradigm that leverages the strengths of both human intuition and computer-based optimization.

Realistic rendering involves the creation of visually realistic images through computer graphics techniques, commonly applied in fields such as film, video games, and computer-aided design. Recent advancements in modern computer architectures and graphics cards have propelled the rapid progress of ray-traced realistic rendering. Formerly confined to offline rendering, these algorithms are now gradually transitioning into real-time computing. While rendering times and processes for realistic rendering have become more straightforward and accessible, implementing rendering algorithms remains a challenge for beginners lacking coding experience. Generic graphics APIs like Vulkan and DirectX, though powerful, demand a significant investment of time for mastery. the implementation process further involves considerations of overall architectural design, algorithm selection, and future scalability. In addition to these challenges, industrial renderers, while offering mature rendering systems, often contain low-level implementations with software-specific APIs and magic numbers. these intricacies can cause confusion and make it nearly impossible for individual developers to extend the system. To overcome these obstacles, this paper aims to enhance accessibility for rendering enthusiasts by constructing a ray-traced realistic rendering engine based on OpenGL. the engine exhibits characteristics such as strong extensibility and ease of use. Furthermore, a clear and efficient CPU-GPU data transfer framework is designed. © 2024 SPIE.

In the context of designing of customized products, ensuring the verification of requirements and stakeholder needs in an efficient and cost-effective manner poses significant challenges. this paper proposes a Virtual Prototyping approach, integrating computer-aided design and multibody modelling, to leverage their respective advantages. the presented case study involves the integration of two pre-existing robots, a cobot and an Autonomous Mobile Robot, to realize an Autonomous Mobile Cobot tailored to the specific needs of a manufacturing industry. through Virtual Prototyping approach, part of the requirements, including spatial and assembly constraint, are verified by means of CAD, while interaction and behavioural requirements are verified through multibody modelling and simulation. this work highlights the efficacy of Virtual Prototyping in achieving comprehensive design verification for tailored products. By simulating the behaviour and performance of the designed system before physical implementation, Virtual Prototyping reduces the time and costs associated with traditional trial-and-error methods. Moreover, it enables a more thorough exploration of design alternatives and optimization strategies, ultimately improving the efficiency and effectiveness of the design process. this integrated approach showcases the potential of digital tools to enhance the development of complex industrial systems, paving the way for tailored solutions to meet evolving market demands.

3DCascade-GAN: Shape completion from single-view depth images

Depth images can be easily acquired using depth cameras. However, these images only contain partial information about the shape due to unavoidable self-occlusion. thanks to the availability of large datasets of shapes, it is possible to use a learning-based approach to produce complete shapes from single depth images. State-of-the-art generative adversarial network (GAN) architectures can produce reasonable results. However, the use of relatively local convolutions restricts GAN architectures from producing globally plausible shapes. In this study, we develop a novel dynamic latent code selection mechanism in which the model learns to select only important codes from the latent space. Furthermore, a novel 3D self-attention (3DSA) layer is introduced that is able to capture non-local relationships across the 3D space. We further design a GAN architecture that uses a multistage encoder-decoder to recover the shape, where our 3DSA layer is introduced to the discriminator to help attend to global features, which stabilizes the model learning and encourages shape refinement, making our reconstruction more structurally plausible. through extensive experiments, we demonstrate that our method outperforms other state-of-the-art methods for single depth image 3D reconstruction. & COPY;2023 the Author(s).

Occluded person re-identification (ReID) is a challenging computer vision task in which the goal is to identify specific pedestrians in occluded scenes across different devices. Some existing methods mainly focus on developing effective data augmentation and representation learning techniques to improve the performance of person ReID systems. However, existing data augmentation strategies can not make full use of the information in the training data to accurately simulate the occlusion scenario, resulting in poor generalization ability. Additionally, recent Vision Transformer (ViT)-based methods have been shown beneficial for addressing occluded person ReID as they have powerful representation learning ability, but they always ignore the information fusion between different levels of features. To alleviate these two issues, an improved ViT-based framework called Parallel Dense Vision Transformer and Augmentation Network (PDANet) is proposed to extract well and robustly features. We first design a parallel data augmentation strategy based on random stripe erasure to enrich the diversity of input sample for better cover real scenes through various processing methods, and improve the generalization ability of the model by learning the relationship between these different samples. We then develop a Densely Connected Vision Transformer (DCViT) module for feature encoding, which strengthens the feature propagation and improves the effectiveness of learning by establishing connections between different layers. Experimental results demonstrate the proposed method outperforms the existing methods on both the occluded person and the holistic person ReID benchmarks.

computer geometric graphics modeling refers to the restoration of the target graphics in the computer graphics environment, and the visual presentation of users, which has been applied in the fields of graphics, virtual reality and computer-aided design. However, the traditional modeling system has some problems, such as low precision and low efficiency, so this paper proposes to use the point cloud data to extract the geometric features of the target graph. In this paper, the Particle swarm optimization-Extreme learning machine (PSO-ELM) algorithm is proposed later, and its principle and operation process are analyzed, and then the algorithm is used to improve the performance of the modeling system. In the comparative experiment of modeling accuracy in this paper, the average modeling accuracy of the intelligent modeling system using the proposed method is 96.97%, while that of the basic system is 94.70%. It is not difficult to see that the experimental results fully reflect the improvement of the modeling accuracy of the modeling system brought by the method in this paper, which is helpful to the application of computer geometric graphics modeling system in practical work. © 2024 the Authors.
