    • A New Sampling Scheme for Slice Based Volume Rendering 

      Krüger, Jens (The Eurographics Association, 2010)
      In this paper we present a novel approach to generate proxy geometry for slice based volume rendering. The basic idea is derived from the behavior of a ray-caster and is a simple extension of the well known 2D object-aligned ...
    • A New Scan Line Algorithm for the Rendering of CGS Trees 

      Pueyo, Xavier; Mendoza, Joan Carles (Eurographics Association, 1987)
      A scan line algorithm is proposed to render CSG modelled solids. Scan planes intersections are obtained by means of a proposed generalisation of Porter’s algorithm. 2-D scan plane primitives are decomposed in a way that ...
    • A new sharp-crease bending element for folding and wrinkling surfaces and volumes 

      Patkar, Saket; Jin, Ning; Fedkiw, Ronald (ACM Siggraph, 2015)
      We present a novel sharp-crease bending element for the folding and wrinkling of surfaces and volumes. Based on a control curve specified by an artist or derived from internal stresses of a simulation, we create a piecewise ...
    • A New Sketch Based Interface using the Gray-level Co-occurrence Matrix for Perceptual Simplification of Paper Based Scribbles 

      Bartolo, Alexandra; Camilleri, Kenneth P.; Farrugia, Philip J.; Borg, Jonathan C. (The Eurographics Association, 2006)
      The sketching activity has an important role in conceptual design and a variety of tools exist which help designers to facilitate the generation of 3D models form sketched drawings. This paper describes a new sketch-to-3D ...
    • A New Space Partitioning for Mapping Computations of the Radiosity Method onto a Highly Pipelined Parallel Architecture 

      Shen, Li-Sheng; Deprettere, E.; Dewilde, P. (The Eurographics Association, 1990)
      Despite the fact that realistic images can be generated by ray-tracing and radiosity shading, these techniques are impractical for scenes of high complexity because of the extremely high time cost. Several attempts have ...
    • A new Subdivision Algorithm for the Intersection of Parametric Surfaces 

      Bühler, Katja (Bühler, June 2001)
      Unterteilungsalgorithmen gehören zu den zuverlässigsten Algorithmen für den Schnitt zweier parametrischer Flächenpatches. Sie erfüllen vier der fünf Anforderungen an einen guten Schnittalgorithmus: Sie sind genau, zuverlässig, ...
