Volumetric Windows: Application to Interpretation of Scientific Data, Shader-Based Rendering Method, and Performance Evaluation

- We present a framework, example application, and rendering methods for volumetric windows, a 3D analog of the 2D windows metaphor. A set of parameters reflected in both implementation and user menus allows windows to behave like 3D volumetric lenses, clip windows, world-in-miniature views, and in other ways. We use programmable hardware shaders to render volumetric windows and we investigate performance of both shader and clipping plane methods. The evaluation considers different dataset and view features as well as the use of data surface tiling for speedup. We apply our work to interactive data viewer windows for managing multiple datasets or multiple views of a dataset in a scientific visualization application.
