Sheared Interpolation and Gradient Estimation for Real-Time Volume Renderings
Proceedings of the Ninth Eurographics conference on Graphics Hardware, 1994.
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.
