Scientific visualization (scivis) is an important tool for all scientific domains that aims to reveal the most salient information out of raw data and display it in an intuitive way so that users can make decisions based on their data characteristics. Virtual reality (VR) is a dedicated technique to render three-dimensional data as a real world interactive and immersive scene. ParaView [2] is a leading open-source scivis software providing many tools for data analysis and visualization. ParaView has been providing VR support for some time now but it has been improved greatly in the last few years, based on feedback from users in the industry and academia alike, especially in regards to menu interactions and collaboration. This work brings insight into the new VR interface and how it provides clear and intuitive access to features and how collaborative VR can be an integral tool for scivis in the future.

Traffic congestion on the roads of the Las Vegas Valley is a growing problem. However, due to the complexity of traffic congestion, it is challenging to find timing problems with traffic signals that contribute to the congestion. informationvisualization, geospatial maps, and modern visualization techniques can help domain experts and the public to analyze, understand, and interact with the data to explore and confirm the causes of traffic congestion. Identifying traffic signals that cause traffic congestion offers domain experts a tool for monitoring traffic signal issues and improving road traffic. Before uncovering road congestion causes, we must first identify the traffic signals or intersections that are most congested to get an overview of the congestion throughout the city's road network. This paper includes preliminary results of a 2D geospatial map design that follows Human-Computer Interaction (HCI) principles of reducing working memory load by providing interactive map features and alternative interfaces for expert and novice users. The informal feedback from a GIS and data visualization specialist on the 2D geospatial map design showed promise, however, for future work the design must be validated with other baseline approaches, data sets, and a user study.

The adoption of Decision Support Systems (DSS) by farmers faces significant challenges, including the need for user-friendly interfaces, comprehensive training, reliable support, and affordable pricing. Addressing these challenges is critical to advancing sustainable agriculture and meeting global food production demands. This paper introduces an advanced DSS tailored for aquaponics, leveraging cutting-edge technologies such as Artificial Intelligence (AI), the Internet of Things (IoT), and Blockchain. These technologies are integrated into the DSS to optimize resource management, ensure cybersecurity, and simplify complex processes through an intuitive interface. Real-time data is presented in an accessible format, enabling farmers of all skill levels to adopt the system with ease. The DSS features AI-driven robotic traps with 75% accuracy in real-time insect detection, autonomous robots achieving 94% precision in 3D spot spraying, and nutrient analyzers with over 92% accuracy in monitoring critical levels. A blockchain layer ensures secure data verification, traceability, and distributed AI model verification. Advanced hierarchical clustering algorithms analyze pest and nutrient dynamics, providing actionable insights for farm management. The system emphasizes interoperability and scalability, supporting seamless integration with various aquaponic setups. Field evaluations demonstrate the DSS's capacity to reduce pesticide use by 50%, enhance crop yields, and lower sample analysis costs by 70%, highlighting its efficiency and sustainability. Data visualization latency remains below 430ms, enabling real-time responsiveness, while predictive models achieve 91% accuracy in forecasting pest population trends. These results solidify the DSS's role as a transformative tool in precision agriculture. By improving productivity, plant health, and the utilization of biopesticides and biofertilizers, this work bridges the gap between theoretical models and real-world applicat

City-scale spatial digital twins require extensive spatial information, such as city-scale point clouds, to remain updated. This study develops a 3D mobile crowdsensing system in which participants collect 3D point cloud data of urban spaces using LiDAR-equipped mobile devices. This system aggregates the collected partial point clouds on a server to merge them into the city digital twin. In such environments, city-scale point clouds are expected to support various smart city tasks. Therefore, diverse types of visualization are necessary for analysis and validation, including task examination, real-time system behavior verification, and crowdsensing system tracking. In this paper, we present a web-based, real-time point cloud visualization mechanism designed to offer tailored views for different use cases.

This study presents a method for visualizing the flow fields around multiple drones intended for gas leak detection in disaster areas, using intermittently generated smoke and image processing. As a preliminary step before conducting experiments with multiple drones, we focused on enhancing visualization performance. An experimental setup was constructed to conduct visualization experiments indoors. This setup is installed in a dark room, where a smoke generator is connected to a duct to create the flow path. Smoke is generated intermittently from the smoke device, and the cross-section of the flow path is extracted using a sheet laser. A transparent panel separates the interior and exterior of the duct, allowing for external image capture with a camera. Optical flow image processing is applied to the captured images, achieving visualization of the entire flow path.
