    • AA Patterns 

      Ahmed, Abdalla G. M. (The Eurographics Association, 2011)
      AA Patterns is the name of a recently developed algorithmic art technique that employs a simple linear 2D transform to generate ornamental patterns of pixels. The patterns are controlled by a single real parameter between ...

    • ABSTRACT DATA TYPE BASED PROGRAMMING STYLE AND COMPUTER GRAPHICS 

      Giloi, W. K. (The Eurographics Association, 1981)
      The next generation of "intelligent" industrial robots will necessitate off-line programming systems in which generative graphics (picture generation) and cognitive graphics (picture understanding) is combined. This will ...

    • Abstract Interaction Objects 

      Duke, D.J.; Harrison, M.D. (Blackwell Science Ltd and the Eurographics Association, 1993)
      The concept of an interactor has been introduced by Faconti and Paterno [6] as an abstraction of an entity in interactive graphics capable of both input and output. However the notion of interaction object need not be ...

    • Accelerated 5D Ray Tree construction on the GPU 

      Kammaje, Ravi P.; Mora, Benjamin (The Eurographics Association, 2011)
      Ray tracing random rays has been a challenge. Due to their reduced coherence, the normal methods of acceleration like packet tracing that make use of coherence of the rays do not work well. These random rays are encountered ...

    • Accelerated Artificial Landscape Visualisation 

      James, A.; Day, A.M. (Eurographics Association, 1999)
      We describe the design and implementation of four stages in an artificial landscape visualisation program. We begin by outlining a very simple but quick method of generating structurally realistic landscapes. We describe ...

    • Accelerated Deterministic Simulation of X-ray Attenuation Using Graphics Hardware 

      Vidal, Franck; Garnier, M.; Freud, N.; Létang, J.M.; John, N.W. (The Eurographics Association, 2010)
      In this paper, we propose a deterministic simulation of X-ray transmission imaging on graphics hardware. Only the directly transmitted photons are simulated, using the Beer-Lambert law. Our previous attempt to simulate ...

    • Accelerated Foveated Rendering based on Adaptive Tessellation 

      Tiwary, Ankur; Ramanathan, Muthuganapathy; Kosinka, Jiri (The Eurographics Association, 2020)
      We propose an optimization method for adaptive geometric tessellation, involving the saccadic motion of the human eye and foveated rendering. Increased demands on computational resources, especially in the field of ...

    • Accelerated Radiosity Method for Complex Environments 

      Xu, Hau; Peng, Qun-Sheng; Liang, You-Dong (Eurographics Association, 1989)
      As form-factor calculation costs about 90% of the computing time when applying radiosity approach for realistic image synthesis, it is of great significance to reduce the required computation, An accelerated radiosity ...

    • Accelerating kd-tree Searches for all k-nearest Neighbours 

      Merry, Bruce; Gain, James; Marais, Patrick (The Eurographics Association, 2013)
      Finding the k nearest neighbours of each point in a point cloud forms an integral part of many point-cloud processing tasks. One common approach is to build a kd-tree over the points and then iteratively query the k nearest ...

    • Accelerating Sphere Tracing 

      Bálint, Csaba; Valasek, Gábor (The Eurographics Association, 2018)
      This paper presents two performance improvements on sphere tracing. First, a sphere tracing variant designed to take optimal step sizes near planar surfaces is proposed. We demonstrate how relaxation is used to make this ...

    • Acceptable System Latency for Gaze-Dependent Level of Detail Rendering 

      Chwesiuk, Michał; Mantiuk, Radoslaw (The Eurographics Association, 2016)
      Human visual system is unable to perceive all details in the entire field of view. High frequency features are noticeable only at a small angle of 1-2 degrees around the viewing direction. Therefore, it is a reasonable ...

    • Accessible GLSL Shader Programming 

      Toisoul, Antoine; Rueckert, Daniel; Kainz, Bernhard (The Eurographics Association, 2017)
      Teaching fundamental principles of Computer Graphics requires a thoroughly prepared lecture alongside practical training. Modern graphics programming rarely provides a straightforward application programming interface (API) ...

    • Accurate and Consistent Reconstruction of Illumination Functions Using Structured Sampling 

      Drettakis, George; Fiume, Eugene (Blackwell Science Ltd and the Eurographics Association, 1993)
      The study of common classes of diffuse emitters, such as planar convex polygons, reveals several interesting properties of the functions of illumination these emitters cast on receiver surfaces. Some properties, such as ...

    • Accurate and Efficient Lighting for Skinned Models 

      Tarini, Marco; Panozzo, Daniele; Sorkine-Hornung, Olga (The Eurographics Association and John Wiley and Sons Ltd., 2014)
      In the context of real-time, GPU-based rendering of animated skinned meshes, we propose a new algorithm to compute surface normals with minimal overhead both in terms of the memory footprint and the required per-vertex ...

    • Accurate Binary Image Selection from Inaccurate User Input 

      Subr, Kartic; Paris, Sylvain; Soler, Cyril; Kautz, Jan (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Selections are central to image editing, e.g., they are the starting point of common operations such as copy-pasting and local edits. Creating them by hand is particularly tedious and scribble-based techniques have been ...
