Real Illumination from Virtual Environments
(The Eurographics Association, 2005)
We introduce a method for actively controlling the illumination in a room so that it is consistent with a virtual world. In combination with a high dynamic range display, the system produces both uniform and directional ...
Light Field Techniques for Reflections and Refractions
(The Eurographics Association, 1999)
Reflections and refractions are important visual effects that have long been considered too costly for interactive applications. Although most contemporary graphics hardware supports reflections off curved surfaces in the ...
Tomographic Reconstruction of Transparent Objects
(The Eurographics Association, 2006)
The scanning of 3D geometry has become a popular way of capturing the shape of real-world objects. Transparent objects, however, pose problems for traditional scanning methods. We present a visible light tomographic ...
Fast Primitive Distribution for Illustration
(The Eurographics Association, 2002)
In this paper we present a high-quality, image-space approach to illustration that preserves continuous tone by probabilistically distributing primitives while maintaining interactive rates. Our method allows for frame-to-frame ...
Bidirectional Importance Sampling for Direct Illumination
(The Eurographics Association, 2005)
Image-based representations for illumination can capture complex real-world lighting that is difficult to represent in other forms. Current importance sampling strategies for image-based illumination have difficulties in ...
Sequential Sampling for Dynamic Environment Map Illumination
(The Eurographics Association, 2006)
Sampling complex illumination in the form of environment maps has received a lot of attention in computer graphics. Recent work in this area has demonstrated that drawing samples from the product of light and BRDF produces ...
Image-Based Reconstruction of Spatially Varying Materials
(The Eurographics Association, 2001)
The measurement of accurate material properties is an important step towards photorealistic rendering. Many real-world objects are composed of a number of materials that often show subtle changes even within a single ...
Interleaved Sampling
(The Eurographics Association, 2001)
The known sampling methods can roughly be grouped into regular and irregular sampling. While regular sampling can be realized efficiently in graphics hardware, it is prone to inter-pixel aliasing. On the other hand these ...
Efficient Cloth Modeling and Rendering
(The Eurographics Association, 2001)
Realistic modeling and high-performance rendering of cloth and clothing is a challenging problem. Often these materials are seen at distances where individual stitches and knits can be made out and need to be accounted ...
