Correct perception of materials requires complex, natural illumination [Fleming et al. 2003]. Thus for material or lighting design applications, realistic, interactive rendering of objects with arbitrary materials under natural illumination is essential. We present a simple and efficient technique for real-time, image-based lighting of objects with(More)
Augmented reality involves mixing captured video with rendered elements in real-time. For augmented reality to be effective in training and simulation applications, the computer generated components need to blend in well with the captured video. Straightforward compositing is not sufficient, since the chromatic content of video and rendered data may be very(More)
We develop the concept of virtual experiments and consider their application to environmental policy. A virtual experiment combines insights from virtual reality in computer science, naturalistic decision-making from psychology, and field experiments from economics. The environmental policy applications of interest to us include traditional valuation tasks(More)
We present a novel approach that allows users to intuitively and interactively manipulate High Dynamic Range (HDR) images using commonly available Low Dynamic Range (LDR) displays. This solves the problem of how to draw with contrasts that are much larger than the monitor can display. Whereas commercial HDR-enabled drawing programs manipulate tone mapped(More)
Figure 1: The BRDF-Shop interface consists of a spherical canvas, where the artist can directly paint highlights and design a unique BRDF, (middle), and simultaneously and in real-time inspect the designed BRDF on a complex model rendered under environment lighting (left). Additionally, the interface was adapted for Maya (right), allowing fast integration(More)

Google Street View has provided millions of users with the ability to visually locate businesses around the world using 360° panoramic imagery. Due to the bulky, custom hardware required to precisely geo-locate the imagery, such as laser scanners and high precision GPS devices, Street View experiences have been limited to large areas that can provide(More)
