Dart Throwing on Surfaces
(The Eurographics Association and Blackwell Publishing Ltd, 2009)In this paper we present dart throwing algorithms to generate maximal Poisson disk point sets directly on 3D surfaces. We optimize dart throwing by efficiently excluding areas of the domain that are already covered by ... -
Decoupling Polygon Rendering from Geometry using Rasterization Hardware
(The Eurographics Association, 1999)The dramatically increasing size of polygonal models resulting from 3D scanning devices and advanced modeling techniques requires new approaches to reduce the load of geometry transfer and processing. In order to supplement ... -
Decoupling Strokes and High-Level Attributes for Interactive Traditional Drawing
(The Eurographics Association, 2001)We present an interactive system, which allows the user to produce drawings in a variety of traditional styles. It takes as input an image and performs semi-automatic tonal modeling. Our system shifts tedious technical ... -
Delivering Interactivity to Complex Tone Mapping Operators
(The Eurographics Association, 2003)The accurate display of high dynamic range images requires the application of complex tone mapping operators. These operators are computationally costly, which prevents their usage in interactive applications. We propose ... -
Detail to Attention: Exploiting Visual Tasks for Selective Rendering
(The Eurographics Association, 2003)The perceived quality of computer graphics imagery depends on the accuracy of the rendered frames, as well as the capabilities of the human visual system. Fully detailed, high fidelity frames still take many minutes even ... -
Deterministic Importance Sampling with Error Diffusion
(The Eurographics Association and Blackwell Publishing Ltd, 2009)This paper proposes a deterministic importance sampling algorithm that is based on the recognition that delta-sigma modulation is equivalent to importance sampling. We propose a generalization for delta-sigma modulation ... -
Differential Point Rendering
(The Eurographics Association, 2001)We present a novel point rendering primitive, called Differential Point (DP), that captures the local differential geometry in the vicinity of a sampled point. This is a more general point representation that, for the cost ... -
Direct Ray Tracing of Phong Tessellation
(The Eurographics Association and Blackwell Publishing Ltd., 2011)There are two major ways of calculating ray and parametric surface intersections in rendering. The first is through the use of tessellated triangles, and the second is to use parametric surfaces together with numerical ... -
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 ... -
Dirty Glass: Rendering Contamination on Transparent Surfaces
(The Eurographics Association, 2007)Rendering of clean transparent objects has been well studied in computer graphics. However, real-world transparent objects are seldom clean their surfaces have a variety of contaminants such as dust, dirt, and lipids. These ... -
Disruptive Technologies in Computer Graphics: Past, Present, and Future
(The Eurographics Association, 1999)The history and famous landmarks of computer graphics hardware are well known. Starting with Ivan Sutherland s Sketchpad system in the early 1960 s, the first generation of computer graphics hardware consisted of calligraphic ... -
A Dual Light Stage
(The Eurographics Association, 2005)We present a technique for capturing high-resolution 4D reflectance fields using the reciprocity property of light transport. In our technique we place the object inside a diffuse spherical shell and scan a laser across ... -
A Dynamic Noise Primitive for Coherent Stylization
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present a new solution for temporal coherence in non-photorealistic rendering (NPR) of animations. Given the conflicting goals of preserving the 2D aspect of the style and the 3D scene motion, any such solution is a ... -
Dynamic Point Distribution for Stroke-based Rendering
(The Eurographics Association, 2007)We present a new point distribution algorithm that is well adapted to stroke-based rendering systems. Its main characteristic is to deal efficiently with three conflicting constraints: the distribution of points should ... -
Effective Compression Techniques for Precomputed Visibility
(The Eurographics Association, 1999)In rendering large models, it is important to identify the small subset of primitives that is visible from a given viewpoint. One approach is to partition the viewpoint space into viewpoint cells, and then precompute a ... -
Efficient and Accurate Rendering of Complex Light Sources
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We present a new method for estimating the radiance function of complex area light sources. The method is based on Jensen s photon mapping algorithm. In order to capture high angular frequencies in the radiance function, ... -
Efficient and Realistic Visualization of Cloth
(The Eurographics Association, 2003)Efficient and realistic rendering of cloth is of great interest especially in the context of e-commerce. Aside from the simulation of cloth draping, the rendering has to provide the "look and feel" of the fabric itself. ... -
Efficient Basis Decomposition for Scattered Reflectance Data
(The Eurographics Association, 2007)Recent progress in acquisition technology has increased the availability and quality of measured appearance data. Although representations based on dimensionality reduction provide the greatest fidelity to measured data, ... -
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 ... -
Efficient Computation of Blue Noise Point Sets through Importance Sampling
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Dart-throwing can generate ideal Poisson-disk distributions with excellent blue noise properties, but is very computationally expensive if a maximal point set is desired. In this paper, we observe that the Poisson-disk ...
