 | Hansen, Charles D. | Constrained inverse volume rendering for planetary nebulae | Determining the three-dimensional structure of distant astronomical objects is a challenging task, given that terrestrial observations provide only one viewpoint. For this task, bipolar planetary nebulae are interesting objects of study because of their pronounced axial symmetry due to fundamental p... | Volume rendering; Axial symmetry | 2004 |

 | 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 |

 | Hansen, Charles D. | Non-photorealistic volume rendering using stippling techniques | Simulating hand-drawn illustration techniques can succinctly express information in a manner that is communicative and informative. We present a framework for an interactive direct volume illustration system that simulates traditional stipple drawing. By combining the principles of artistic and sci... | Volume rendering; Non-photorealistic rendering; Scientific visualization; Medical imaging | 2002 |
