Free form deformation has applications in computer animation, in data acquisition , and in computer aided geometric design. One approach is to deform the space in order to induce a deformation of an embedded object. A new method of this class is proposed which is based on scattered data interpolation. The usefulness of two selected classes of scattered data interpolation methods in this context...

Some important trends in geometric modeling are the reliance on solid models rather than surface-based models and the enhancement of the expressive power of models, by using free-form objects in addition to the usual geometric primitives and by incorporating physical principles. An additional trend is the emphasis on interactive performance. In this paper we integrate all of these requirements ...

This paper presents methods for photo-realistic rendering using strongly spatially variant illumination captured from real scenes. The illumination is captured along arbitrary paths in space using a high dynamic range, HDR, video camera system with position tracking. Light samples are rearranged into 4-D incident light fields (ILF) suitable for direct use as illumination in renderings. Analysis...
