We present a novel rendering system for defocus blur and lens effects. It supports physically-based rendering and outperforms… Expand We propose a new approach to efficiently render large volumetric data sets. The system achieves interactive to real-time… Expand In this paper we present the first practical method for importance sampling functions represented as spherical harmonics (SH… Expand This paper introduces feature-based textures, a new image representation that combines features and samples for high-quality… Expand A software package has been developed, allowing to visualise simultaneously several data-sets in real-time without the need of… Expand We propose a new technique for efficiently rendering bidirectional texture functions (BTFs). A 6D BTF describesthe appearance of… Expand We describe the clipmap, a dynamic texture representation that efficiently caches textures of arbitrarily large size in a finite… Expand Texture mapping is a fundamental feature of computer graphics image generation. In current PC-based acceleration hardware, MIP… Expand Volumetric textures are able to represent complex repetitive data such as foliage, fur and forests by storing one sample of… Expand We direct our gaze at an object by rotating our eyes or head until the object's projection falls on the fovea, a small region of… Expand
