Hansen, Charles D. | Gaussian transfer functions for multi-field volume visualization | Volume rendering is a flexible technique for visualizing dense 3D volumetric datasets. A central element of volume rendering is the conversion between data values and observable quantities such as color and opacity. This process is usually realized through the use of transfer functions that are prec... | Volume rendering; Transfer functions; Volume visualization | 2003 |

Weinstein, David | Hierarchical data structures for interactive volume visualization | In order to interactively investigate large-scale 3D data sets, we propose an improved hierarchical data structure for structured grids and an original hierarchical d a t a structure for unstructured grids. These multi-tiered implementations allow the user to interactively control both the local and... | Hierarchical data structures; Volume visualization; 3D data sets | 1995 |

Hansen, Charles D.; Whitaker, Ross T. | Interactive deformation and visualization of level set surfaces using graphics hardware | Deformable isosurfaces, implemented with level-set methods, have demonstrated a great potential in visualization for applications such as segmentation, surface processing, and surface reconstruction. Their usefulness has been limited, however, by their high computational cost and and reliance on sig... | Deformation; Level sets; Deformable models; Image segmentation; Volume visualization; GPU; Streaming computation; Isosurfaces | 2003 |

Parker, Steven G.; Hansen, Charles D.; Shirley, Peter S. | Interactive ray tracing for volume visualization | We present a brute-force ray tracing system for interactive volume visualization, The system runs on a conventional (distributed) shared-memory multiprocessor machine. For each pixel we trace a ray through a volume to compute the color for that pixel. Although this method has high intrinsic computa... | Ray tracing; Volume visualization; Isosurfaces; Maximum-intensity projection; Traversal optimizations | 1999 |

Hansen, Charles D. | Interactive translucent volume rendering and procedural modeling | Direct volume rendering is a commonly used technique in visualization applications. Many of these applications require sophisticated shading models to capture subtle lighting effects and characteristics of volume metric data and materials. Many common objects and natural phenomena exhibit visual qua... | Volume rendering; Volume visualization; Direct volume rendering; Multidimensional transfer functions; Direct manipulation widgets; Graphics hardware | 2002 |

Parker, Steven G.; Hansen, Charles D. | Interactive volume rendering of large datasets using the silicon graphics Onyx4 visualization system | Many recent approaches to interactive volume rendering have focused on leveraging the power of commodity graphics hardware. Though currently limited to relatively small datasets, these approaches have been overwhelmingly successful. As the size of volumetric datasets continues to grow at a rapid pa... | Volume visualization; Onyx4; Interactive volume rendering; Parallel volume rendering; Large datasets; Visualization systems | 2005 |

Hansen, Charles D. | Interactive volume rendering using multi-dimensional transfer functions and direct manipulation widgets | Most direct volume renderings produced today employ onedimensional transfer functions, which assign color and opacity to the volume based solely on the single scalar quantity which comprises the dataset. Though they have not received widespread attention, multi-dimensional transfer functions are a v... | Volume rendering; Volume visualization; Direct volume rendering; Multidimensional transfer functions; Direct manipulation widgets; Graphics hardware | 2001 |

Hansen, Charles D.; Tasdizen, Tolga | Statistically quantitative volume visualization | Visualization users are increasingly in need of techniques for assessing quantitative uncertainty and error in the images produced. Statistical segmentation algorithms compute these quantitative results, yet volume rendering tools typically produce only qualitative imagery via transfer function-base... | Volume visualization; Uncertainty; Classification; Risk analysis | 2005 |
