    By splitting a complex ray-casting process into different tasks performed on different processors, Voreen provides a lot of flexibility because users can intervene at different points during ray casting. Voreen's object-oriented design lets users easily create customized processor classes that cooperate seamlessly with existing classes. A user-friendly GUI supports rapid prototyping of visualizati...

    In situ visualization is clearly a promising solution for ultrascale simulations. We've seen some success in realizing this solution and in ongoing efforts to add support for in situ visualization to open source visualization toolkits such as ParaView and Visit. However, for others to adopt this approach, we need further research and experimental studies to derive a set of guidelines and usable vi... View full abstract»

    In this article, we study the impact of such eye-hand visibility mismatch on selection tasks performed with hand-rooted pointing techniques. We propose a new mapping for ray control, called Ray Casting from the Eye (RCE), which attempts to overcome this mismatch's negative effects. In essence, RCE combines the benefits of image-plane techniques (the absence of visibility mismatch and continuity of... View full abstract»

    A new method for analyzing 3D goal-directed movements provides more insights than existing approaches by dividing them into meaningful phases. An experiment applying a simple 3D task, resembling a standardized 2D multidirectional pointing task, yielded insights that can help researchers better identify input devices' and interaction techniques' strengths and weaknesses.

  • Spatial Input for Temporal Navigation in Scientific Visualizations

    Publication Year: 2009, Page(s):54 - 64
    Cited by:  Papers (3)

    Scientific-visualization tools can make time-varying simulations easier to understand. The growing efficiency of today's high-performance computers enables simulation of physical phenomena with a high temporal resolution. Consequently, visualization systems require efficient navigation in the temporal dimension. This 3D user interface employs direct-manipulation metaphors for temporal navigation i...

  • Navigation Tools for Viewing Augmented CAD Models

    During the production of an object, design modifications can occur because of, for example, corrections of design flaws, third-party components that must be replaced but are unavailable, or simply mistakes. So, undocumented discrepancies might exist between the CAD model and the final object. Although such discrepancies might not have consequences for the object's functionality, this gap between t...

    This paper presents an approach to image coding that first paints a regularly arranged dotted pattern, using colors picked from a texture sample with features corresponding to the embedded data. It then camouflages the dotted pattern using the same texture sample while preserving quality comparable to that of existing synthesis techniques. View full abstract»

    Real-time crowd simulations are realistic only if each human instance looks unique. A proposed solution varies the shape of human instances by attaching accessories. It also modifies the instances' appearance with a generic technique based on segmentation maps that can generate detailed color variety and patterns. View full abstract»
