      Hjelmervik, Jon M.; Fuchs, Franz G. (The Eurographics Association, 2015)
      Flexible surface types on irregular grids, such as T-splines and LR-splines, are gaining popularity in science and industry due to the possibility for local grid refinement. We present a novel rendering algorithm for those ...

    • Interactive Planarization and Optimization of 3D Meshes 

      Poranne, Roi; Ovreiu, Elena; Gotsman, Craig (The Eurographics Association and Blackwell Publishing Ltd., 2013)
      Constraining 3D meshes to restricted classes is necessary in architectural and industrial design, but it can be very challenging to manipulate meshes while staying within these classes. Specifically, polyhedral meshesâ ...

    • Interactive Point-Based Modeling from Dense Color and Sparse Depth 

      Popescu, Voicu; Sacks, Elisha; Bahmutov, Gleb (The Eurographics Association, 2004)
      We are developing a system for interactive modeling of real world scenes. The acquisition device consists of a video camera enhanced with an attached laser system. As the operator sweeps the scene, the device acquires dense ...

    • Interactive Polygonisation for Function-based Modelling 

      Sourin, Alexei; Levinski, Konstantin (Eurographics Association, 2002)
      This paper addresses interactive function-based shape modelling. Interactive modification of the function model with concurrent visualization of the respective polygonal mesh lets us provide both the interactivity and any ...

    • Interactive Position-dependent Customization of Transfer Function Classification Parameters in Volume Rendering 

      Brix, Tobias; Scherzinger, Aaron; Völker, Andreas; Hinrichs, Klaus (The Eurographics Association, 2015)
      In direct volume rendering (DVR) and related techniques a basic operation is the classification of data values by mapping (mostly scalar) intensities to color values using a transfer function. However, in some cases this ...

    • Interactive Previewing for Transfer Function Specification in Volume Rendering 

      Botha, Charl P.; Post, Frits H. (The Eurographics Association, 2002)
      This paper presents a new technique for supplying meaningful visual feedback during direct volume rendering transfer function specification. The technique uses meta-data calculated during a pre-processing step to generate ...

    • Interactive Procedural Modelling of Coherent Waterfall Scenes 

      Emilien, Arnaud; Poulin, Pierre; Cani, Marie‐Paule; Vimont, Ulysse (Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
      Combining procedural generation and user control is a fundamental challenge for the interactive design of natural scenery. This is particularly true for modelling complex waterfall scenes where, in addition to taking charge ...

    • Interactive Programming for Parametric CAD 

      Mathur, Aman; Pirron, Marcus; Zufferey, Damien (© 2020 Eurographics ‐ The European Association for Computer Graphics and John Wiley & Sons Ltd, 2020)
      Parametric computer‐aided design (CAD) enables description of a family of objects, wherein each valid combination of parameter values results in a different final form. Although Graphical User Interface (GUI)‐based CAD ...

    • Interactive Projective Texturing for Non-Photorealistic Shading of Technical 3D Models
