Large fused GPU volume rendering

This master thesis describes the underlying theory and implementation of a fused GPU volume rendering pipeline. The open source framework of XIP, largely developed at Siemens Corporate Research, is extended with fusion capabilities through a Binary Space Partitioning approach. Regions in the intersection pattern of multiple volumes are identified and subsequently rendered using either Texture Slicing or Raycasting in a cell based fashion. Results demonstrate interactive frame rates for reasonable scenes and are encouraging as the implementation can be extended by several key acceleration methods.
