The correct choice of function and derivative reconstruction filters is paramount to obtaining highly accurate renderings. Most filter choices are limited to a set of commonly used functions, and the visualization practitioner has so far no way to state his preferences in a convenient fashion. Much work has been done towards the design and specification of(More)
me process of generating discrete surfaces in a volumetric representation , termed voxe~zation, is cotionted with topologid considerations as we~ as accuracy and efficiency requirements. We introduce a new method for voxehg planar objects which,-e existing methods, provides topolo~cd conformity through geometric measures. We extend our approach to provide,(More)
We introduce a new approach for the deformation of surface and raster models in two and three dimensions. Rather then deforming the model, we deform the rendering agents employed to render it. We introduce the deflectors: a new set of operators for modeling both continuous and discontinuous deformations. When the scene is rendered by ray tracings, the(More)
This paper advocates the use of a group of renderers rather than any specific rendering method. We describe a bundle containing four alternative approaches to visualizing volume data. One new approach uses realistic volumetric gas rendering techniques to produce photo-realistic images and animations. The second uses ray casting that is based on a simpler(More)
Advanced display technologies have made the virtual exploration of relatively complex models feasible in many applications. Unfortunately, only a few human interfaces allow natural interaction with the environment. Moreover, in surgical applications, such realistic interaction requires real-time rendering of volumetric data-placing an overwhelming(More)
This paper describes three alternative volume rendering approaches to visualizing computational fluid dynamics (CFD) data. One new approach uses realistic volumetric gas rendering techniques to produce photo-realistic images and animations from scalar CFD data. The second uses ray casting that is based on a simpler illumination model and is mainly centered(More)
