We describe an augmented reality, optical see-through display based on a DMD chip with an extremely fast (16 kHz) binary update rate. We combine the techniques of post-rendering 2-D offsets and just-in-time tracking updates with a novel modulation te

In mobile devices, limiting the Graphics Processing Unit's (GPU's) energy usage is of great importance to extending battery life. This work shows that significant energy savings can be obtained by reducing the precision of graphics computations, yet

We introduce a technique to rapidly generate summed-area tables using graphics hardware. Summed area tables, originally introduced by Crow, provide a way to filter arbitrarily large rectangular regions of an image in a constant amount of time. Our al

Immersive electronic books (IEBooks) for surgical training will let surgeons explore previous surgical procedures in 3D. The authors describe the techniques and tools for creating a preliminary IEBook, embodying some of the basic concepts.

Most surfaces, including most fabrics, have different reflectance at different points on the surface. The reflectance also varies based on the incident and exitant light directions. This spatially and angularly varying surface appearance is a 6D func

We introduce and present preliminary results for a hybrid display system combining head-mounted and projector-based displays. Our work is motivated by a surgical training application where it is necessary to simultaneously provide both a highfidelity

We present initial results from a new image generation approach for low-latency displays such as those needed in head-worn AR devices. Avoiding the usual video interfaces, such as HDMI, we favor direct control of the internal display technology. We i

What is visualization of the real world? In our view, it means visualizing the environments around us, at scales we're accustomed to, sensing what we would normally sense. Unlike others in the field of visualization, we don't aim to provide X-ray vis

We are investigating techniques for providing smooth transitions when simplifying large, static geometric models with texture-based representations (or impostors). Traditionally, textures have been used to replace complex geometry, for example the bo
