Abstract
Volume rendering is a technique for the display of data sampled in three dimensions. Traditionally, visualization of such data has been done indirecdy through some intermediate classification where the volume data are transformed into a form (points, lines or surfaces) suitable for display. This approach is being replaced by new techniques which operate directly on the three dimensional data to avoid the artifacts introduced by the use of conventional graphics primitives.
In this paper we address the problem of extending volume rendering to handle polygonally defined objects. The solution we propose is a set of hybrid rendering techniques where the polygonal data are rendered using a standard z-buffer algorithm. The volume data are rendered either with a front-to-back cell based algorithm, a 3D texture mapping algorithm, raytracing, or as multiple 3D contoured surfaces (honeycomb). The techniques are used to display results from gas explosion simulations and multi-phase flow simulations.
