Abstract

Most volume rendering systems based on raycasting still suffer from inefficient CPU utilization and bad cache coherence. The recently introduced hyper-threading technology provides a solution to the first problem. This paper describes a raycasting system based on this new technology. To address the second problem the system is based on a bricked memory-layout. Bricking, however, requires an efficient addressing of data within and between blocks. We achieve this through two advanced address look-up tables.
