      Anjyo, Ken-ichi (Eurographics Association, 1990)
      Semi-globalized spectral synthesis is proposed as a new tool for three-dimensional scene description consisting of many natural objects, such as terrain, sea waves, and clouds. The method is based on the mathematical theory ...

    • Mathematics Input for Educational Applications in Virtual Reality 

      Sansonetti, Luigi; Chatain, Julia; Caldeira, Pedro; Fayolle, Violaine; Kapur, Manu; Sumner, Robert W. (The Eurographics Association, 2021)
      Virtual Reality (VR) enables new ways of learning by providing an interactive environment to learn through failure and by allowing new interaction methods engaging the users' bodies. Literature from productive failure and ...

    • Matisse: Painting 2D regions for Modeling Free-Form Shapes 

      Bernhardt, Adrien; Pihuit, Adeline; Cani, Marie-Paule; Barthe, Loic (The Eurographics Association, 2008)
      This paper presents Matisse, an interactive modeling system aimed at providing the public with a very easy way to design free-form 3D shapes. The user progressively creates a model by painting 2D regions of arbitrary ...

    • MatMorpher: A Morphing Operator for SVBRDFs 

      Gauthier, Alban; Thiery, Jean-Marc; Boubekeur, Tamy (The Eurographics Association, 2021)
      We present a novel morphing operator for spatially-varying bidirectional reflectance distribution functions. Our operator takes as input digital materials modeled using a set of 2D texture maps which control the typical ...

    • Matrix Bidirectional Path Tracing 

      Chaitanya, Chakravarty Reddy Alla; Belcour, Laurent; Hachisuka, Toshiya; Premoze, Simon; Pantaleoni, Jacopo; Nowrouzezahrai, Derek (The Eurographics Association, 2018)
      Sampled paths in Monte Carlo ray tracing can be arbitrarily close to each other due to its stochastic nature. Such clumped samples in the path space tend to contribute little toward an accurate estimate of each pixel. ...

    • Matrix Reordering Methods for Table and Network Visualization 

      Behrisch, Michael; Bach, Benjamin; Riche, Nathalie Henry; Schreck, Tobias; Fekete, Jean-Daniel (The Eurographics Association and John Wiley & Sons Ltd., 2016)
      This survey provides a description of algorithms to reorder visual matrices of tabular data and adjacency matrix of networks. The goal of this survey is to provide a comprehensive list of reordering algorithms published ...

    • Matrix Trees 

      Andrysco, Nathan; Tricoche, Xavier (The Eurographics Association and Blackwell Publishing Ltd., 2010)
      We propose a new data representation for octrees and kd-trees that improves upon memory size and algorithm speed of existing techniques. While pointerless approaches exploit the regular structure of the tree to facilitate ...

    • A Matrix-Based Visual Comparison of Time Series Sports Data 

      Beck, Fabian; Burch, Michael; Weiskopf, Daniel (The Eurographics Association, 2016)
      In sports, large amounts of data are measured and stored with the help of modern sensors and electronic devices. In particular, for endurance sports events, time-varying data are recorded and can be used to analyze the ...

    • Matting and Compositing for Fresnel Reflection on Wavy Surfaces 

      Endo, Yuki; Kanamori, Yoshihiro; Fukui, Yukio; Mitani, Jun (The Eurographics Association and Blackwell Publishing Ltd., 2012)
