In many volume segmentation and visualization tasks, the ability to correctly identify the boundary surface of each volumetric feature of interest in the data is desirable. This surface can be used in subsequent quantitative studies of the segmented …
We present an event-based scheduling method for time-critical collision detection that meets time constraints by balancing and prioritizing computation spent on intersection tests without starvation. Our approach tests each potentially colliding pair …
We introduce a system that adds a foveal inset to large-scale projection displays. The effective resolution of the foveal inset projection is higher than the original display resolution, allowing the user to see more details and finer features in …

Continued advances in display hardware, computing power, networking, and rendering algorithms have all converged to dramatically improve large high-resolution display capabilities. We present a survey on prior research with large high-resolution …
Egocentric distance perception over distances of 2--20 meters has been extensively studied within real world environments and within virtual environments (VEs) using head-mounted displays (HMDs). Not as much investigation has been performed within …
To advance research and improve the scientific return on data collection and interpretation efforts in the geosciences, we have developed methods of interactive visualization, with a special focus on immersive virtual reality (VR) environments. Earth …
We introduce the 3D warp brush, a method for interactive shape modeling in a immersive virtual reality environment. 3D warp brushes are implicitly-definedtools that operate on triangle meshes. We combine the efficiency of explicit mesh …
Much work has been done on the development of laser pointers as interaction devices. Typically a camera captures images of a display surface and extracts a laser pointer dot location. This location is processed and used as a cursor position. While …
