Abstract

Since the 90s, the Direct Volume Rendering shows itself as an efficient tool for the visual analysis of volumetric datasets. There are approaches that allow for the real-time Ray Casting for visualization of the datasets that can be divided into bricks and entirely loaded into the GPU memory. We describe particular details, implemented in our volume rendering engine, that significantly improve rendering quality and performance.
