Two-phase perspective ray casting for interactive volume navigation
Proceedings. Visualization '97 (Cat. No. 97CB36155)
Volume navigation is the interactive exploration of volume data sets by "flying" the view point through the data, producing a volume rendered view at each frame. In this paper, we present an inexpensive perspective volume navigation method designed to run on a PC platform with acceIerated 3D graphics hardware. We compute perspective projections at each frame, allow trilinear interpolation of sample points, and render both gray scale and RGB volumes by volumetric compositing.
