	abstract = {In this paper we present a technique for the interactive control and display of static and dynamic 3D datasets. We describe novel ways of tri-linear interpolation and gradient estimation for a real-time volume rendering system, using coherency between rays. We show simulation results that compare the proposed methods to traditional algorithms and present them in the cantezt of Cube-B, a special-purpose architecture capable of rendering 5123 16-bit per voxel datasets at over 20 frames per second.},
