Consideration to A Pseudo-Perspective Projection in Large Scale Volume Rendering

In a large scale visualization with a wide screen, parallel projection becomes no more acceptable. However, real-time rendering using perspective projection is relatively expensive to support, due to increasing irregularity in memory access patterns. So, we have been investigating a technique which we call Pseudo-Perspective Projection. This method simulates a perspective projection by a collection of multiple parallel projections. In this paper, we have examined the quality of images rendered with the pseudo-perspective projection.
