Symmetric Photography: Exploiting Data-sparseness in Reflectance Fields
(The Eurographics Association, 2006)
We present a novel technique called symmetric photography to capture real world reflectance fields. The technique models the 8D reflectance field as a transport matrix between the 4D incident light field and the 4D exitant ...
Wavelet Radiance Transport for Interactive Indirect Lighting
(The Eurographics Association, 2006)
Global illumination is a complex all-frequency phenomenon including subtle effects caused by indirect lighting. Computing global illumination interactively for dynamic lighting conditions has many potential applications, ...
Warping and Partitioning for Low Error Shadow Maps
(The Eurographics Association, 2006)
We evaluate several shadow map algorithms based on warping and partitioning using the maximum perspective aliasing error over the entire view frustum. With respect to our error metric, we show that a range of warping ...
Reconstruction of Volumetric Surface Textures for Real-Time Rendering
(The Eurographics Association, 2006)
Volumetric texturing is a popular technique for rendering rich 3-D detail when a polygonal surface representation would be ineffective. Although efficient algorithms for rendering volumetric textures have been known for ...
Antialiasing for Automultiscopic 3D Displays
(The Eurographics Association, 2006)
Automultiscopic displays show stereoscopic images that can be viewed from any viewpoint without special glasses. They hold great promise for the future of television and digital entertainment. However, the image quality ...
Interactive Screen-Space Accurate Photon Tracing on GPUs
(The Eurographics Association, 2006)
Recent advances in algorithms and graphics hardware have opened the possibility to render caustics at interactive rates on commodity PCs. This paper extends on this work in that it presents a new method to directly render ...
Image-driven Navigation of Analytical BRDF Models
(The Eurographics Association, 2006)
Specifying parameters of analytic BRDF models is a difficult task as these parameters are often not intuitive for artists and their effect on appearance can be non-uniform. Ideally, a given step in the parameter space ...
Directing Gaze in 3D Models with Stylized Focus
(The Eurographics Association, 2006)
We present an interactive system for placing emphasis in stylized renderings of 3D models. The artist chooses a camera position, an area of interest, and a rendering style for the scene. The system then automatically renders ...
Instant Ray Tracing: The Bounding Interval Hierarchy
(The Eurographics Association, 2006)
We introduce a new ray tracing algorithm that exploits the best of previous methods: Similar to bounding volume hierarchies the memory of the acceleration data structure is linear in the number of objects to be ray traced ...
Ardeco: Automatic Region DEtection and COnversion
(The Eurographics Association, 2006)
We present Ardeco, a new algorithm for image abstraction and conversion from bitmap images into vector graphics. Given a bitmap image, our algorithm automatically computes the set of vector primitives and gradients that ...
