    • Architectures for Real-Time Volume Rendering 

      Pfister, Hanspeter (Elsevier, 1999)
      Over the last decade, volume rendering has become an invaluable visualization technique for a wide variety of applications. This paper reviews three special-purpose architectures for interactive volume rendering: texture ...
    • The Computational Complexity of Cartographic Label Placement 

      Marks, Joe; Shieber, Stuart Merrill (1991)
      We examine the computational complexity of cartographic label placement, a problem derived from the cartographer's task of placing text labels adjacent to map features in such a way as to minimize overlaps with other labels ...
    • Layered depth images 

      Shade, Jonathan; Gortler, Steven; He, Li-wei; Szeliski, Richard (Association for Computing Machinery, 1998)
      In this paper we present a set of efficient image based rendering methods capable of rendering multiple frames per second on a PC. The first method warps Sprites with Depth representing smooth surfaces without the gaps ...
    • A Local/Global Approach to Mesh Parameterization 

      Liu, Ligang; Zhang, Lei; Xu, Yin; Gotsman, Craig; Gortler, Steven (Eurographics Association and Blackwell Publishing Ltd., 2008)
      We present a novel approach to parameterize a mesh with disk topology to the plane in a shape-preserving manner. Our key contribution is a local/global algorithm, which combines a local mapping of each 3D triangle to the ...
    • Modeling Mitral Valve Leaflets from Three-Dimensional Ultrasound 

      Howe, Robert D.; Schneider, Robert J.; Burke, William Conroy; Marx, Gerald Ross; Del Nido, Pedro J. (Springer Science + Business Media, 2011)
      The geometry of the mitral leaflets, most commonly viewed using three-dimensional ultrasound, is an important input for mechanical models predicting valve closure. Current methods for leaflet modeling from ultrasound either ...
    • A Perception-based Color Space for Illumination-invariant Image Processing 

      Chong, Hamilton; Gortler, Steven; Zickler, Todd (Association for Computing Machinery, 2008)
      Motivated by perceptual principles, we derive a new color space in which the associated metric approximates perceived distances and color displacements capture relationships that are robust to spectral changes in illumination. ...
    • Rendering Deformable Surface Reflectance Fields 

      Weyrich, Tim; Pfister, Hanspeter; Gross, Markus (Institute of Electrical and Electronics Engineers, 2005)
      Animation of photorealistic computer graphics models is an important goal for many applications. Image-based modeling has emerged as a promising approach to capture and visualize real-world objects. Animating image-based ...
    • Signal-specialized parameterization for piecewise linear reconstruction 

      Tewari, Geetika; Snyder, John; Sander, Pedro V.; Gortler, Steven; Hoppe, Hugues (Eurographics Association/ Association for Computing Machinery, 2004)
      We propose a metric for surface parameterization specialized to its signal that can be used to create more efficient, high-quality texture maps. Derived from Taylor expansion of signal error, our metric predicts the signal ...
    • Simple silhouettes for complex surfaces 

      Kirsanov, Danil; Sander, Pedro V.; Gortler, Steven (Eurographics Association/ Association for Computing Machinery, 2003)
      Complex meshes tend to have intricate, detailed silhouettes. This paper proposes two algorithms for extracting a simpler, approximate silhouette from a high-resolution model. Our methods preserve the important features of ...
    • Wavelet Radiosity 

      Gortler, Steven; Schröder, Peter; Cohen, Michael F.; Hanrahan, Pat (Association for Computing Machinery, 1993)
      Radiosity methods have been shown to be an effective means to solve the global illumination problem in Lambertian diffuse environments. These methods approximate the radiosity integral equation by projecting the unknown ...
