Image Editing with Intelligent Paint
(Eurographics Association, 2002)Intelligent Paint provides a new tool for interactively selecting image objects or regions of interest, while simultaneously applying filters or effects directly to the selection(s). By coupling adaptive cost-ordered region ... -
An Image-Based Radiosity Representation
(Eurographics Association, 2002)We present a geometry-independent radiosity representation which stems from image-based methodologies. Our image-based representation is inspired by the concept of layered depth images. To construct the radiosity function ... -
Improved Bump Mapping by using Quadratic Vector Interpolation
(Eurographics Association, 2002)Bump mapping is a technique that perturbs normals used in the illumination computation in order to make the surface appear rough or wrinkled. Standard graphics hardware linearly interpolates rotated vectors in the direction ... -
Improved Integration for Cloth Simulation
(Eurographics Association, 2002)Most methods of cloth simulation produce animations that do not move very freely; the result often looks like the material is “swimming”. The primary sources of this phenomenon are the non-physical dissipation terms often ... -
Information-Theoretic Oracle Based on Kernel Smoothness for Hierarchical Radiosity
(Eurographics Association, 2002)One of the main problems in the radiosity method is how to discretise the surfaces of a scene into mesh elements that allow us to accurately represent illumination. In this paper we present a robust information-theoretic ... -
Interactive High-Quality Volume Rendering with Flexible Consumer Graphics Hardware
(Eurographics Association, 2002)Recently, the classic rendering pipeline in 3D graphics hardware has become flexible by means of programmable geometry engines and rasterization units. This development is primarily driven by the mass market of computer ... -
Interactive Polygonisation for Function-based Modelling
(Eurographics Association, 2002)This paper addresses interactive function-based shape modelling. Interactive modification of the function model with concurrent visualization of the respective polygonal mesh lets us provide both the interactivity and any ... -
Interactive Visualization with Programmable Graphics Hardware
(Eurographics Association, 2002)One of the main scientific goals of visualization is the development of algorithms and appropriate data models which facilitate interactive visual analysis and direct manipulation of the increasingly large data sets which ... -
Interpolating 2D Shape Hierarchically
(Eurographics Association, 2002)Shape interpolation has been widely used in the field of computer graphics for modeling and for creating visual effects. This paper presents a novel hierarchical method to interpolate between two 2D shapes. A hierarchical ... -
Knowledge-Based Representation of Cinematic Expression and its Application to Animation
(Eurographics Association, 2002)Camera control in virtual environments received growing attention recently, and some of the research turned to cinematography as a source for inspiration. Cinematic knowledge is a highly challenging domain for formalization. ... -
Measuring and Rendering Art Paintings Using an RGB Camera
(Eurographics Association, 2002)A method is proposed for measuring and rendering of art paints by using the simple system of an RGB camera only. The surface shape of an art painting is considered as a rough plane rather than a three-dimensional curved ... -
Mesh Decimation for Displacement Mapping
(Eurographics Association, 2002)We present a mesh decimation algorithm for triangular meshes. Unlike other decimation algorithms we are not concerned with geometric error but with the existence of a displacement mapping which can map between the original ... -
A Method for Creating Mosaic Images Using Voronoi Diagrams
(Eurographics Association, 2002)This paper proposes a non-photorealistic rendering method that creates an artistic effect called mosaicing. The proposed method converts images provided by the user into the mosaic images. Commercial image editing applications ... -
Modeling and Rendering of Synthetic Plants
(Eurographics Association, 2002)Plant geometries: → important for many indoor and outdoor scenes → hard to generate and to manipulate → tricky to convert → today: seldomly used → tomorrow: standard of most animation systems -
Modeling Visual Attention in VR: Measuring the Accuracy of Predicted Scanpaths
(Eurographics Association, 2002)Dynamic human vision is an important contributing factor to the design of perceptually-based Virtual Reality. A common strategy relies on either an implicit assumption or explicit measurement of gaze direction. Given the ... -
More than RGB: Spectral Trends in Color Reproduction
(Eurographics Association, 2002)Early rendering algorithms relied exclusively on three-dimensional spaces for color computation, such as RGB and CIE XYZ. Recent rendering advances use full spectral information for illuminants and surfaces, resulting in ... -
Multi-dimensional and Multi-scale Visualizer of Large XML Documents
(Eurographics Association, 2002)3D-XV (3-Dimensional XML Visualizer) is an interactive graphical interface for accessing large structured documents. It relies on a geometrical model that combines a sequential organization and a hierarchical structure. ... -
Normal Enhancement for Interactive Non-photorealistic Rendering
(Eurographics Association, 2002)We present a simple technique to improve the perception of shape of an object. Bump mapping is well-known in the computer graphics community for providing the impression of small-scale geometrical features (which actually ... -
On the Integration of Synthetic Objects with Real-World Scenes
(Eurographics Association, 2002)This paper presents a method for integrating synthetic objects in real-world photographs. We take a set of photographs of a real scene and build a simple image-based model. We use high dynamic range images to build an ...
