Summary: The study used patient CT and MRI data to create 3D virtual models for comparing surgical approaches. By measuring surgical freedom to specific regions and recording visually blocked tumor portions for comparison, it was found that some approaches provided better visualization of the tumor volume.

Summary: This study describes the design and application of a novel advanced protocol for virtual three-dimensional anatomical reconstruction of the deep facial compartments, aiming to improve the preoperative understanding and the intraoperative assistance in complex resective surgeries. The study included seven patients with successful application of the protocol, achieving overall reconstruction rates superior to 90% for major caliber vessels. Virtual surgical planning and multilayer anatomical reconstruction proved to be valuable methods in improving surgical outcomes in deep facial compartments.

Summary: In this study, we developed a webXR tool that utilizes Google Cardboard to help students visualize 3D graphs from functions of two variables in the classroom. We evaluated the usability of Google Cardboard as a content delivery system in a multivariable calculus class and compared it with PowerPoint slides. The results indicate that Google Cardboard is more effective than PowerPoint slides in enhancing students' attitudes and engagement towards learning multivariable calculus, while its usability does not significantly differ from PowerPoint slides.

Summary: Despite recent advances in Immersive Analytics, there is a lack of research on 3D graph aesthetics beyond the desktop. This paper investigates the use of curvature aesthetics for edges in 3D graph visualisation and compares three curvature approaches against straight lines. Two studies were conducted to observe user preferences and performance when navigating curved graphs in Virtual Reality (VR) with and without topological-based tasks. The results show that curved edges without specified orientations performed worse in both performance and preference compared to Lombardi-inspired implementations of edges. Pupillary response and navigation approaches were indicative of the edges' performance for topological-based tasks.

Summary: Cybersickness remains a challenge in virtual reality, especially during navigation in 3D environments. This study focuses on the impact of distance from barriers and choice of navigation interface on cybersickness levels. Experimental results suggest suggestions for optimal navigation to significantly reduce cybersickness and enhance user experience.

Summary: This article explores the issue of viewing and navigating cities in virtual environments and proposes an intuitive navigation interface called UrbanRama that combines local and global views. Through iterative design and collaboration with architects and urban planners, the system effectively reduces perspective changes while maintaining distance and orientation perception. The findings from qualitative and quantitative user studies demonstrate the effectiveness of UrbanRama.

Summary: This study analyzed the impact of three-dimensional-virtual reality technology on surgical planning and anatomical structure identification in patients with anterior skull base meningiomas. The results showed that the 3D-VR modality significantly influenced the detection of tumor-related anatomical structures, recommended head positioning, and surgical approach, allowing for a greater understanding of anatomy and pathology, and influencing operation planning and strategy.
