摘要

We present a new GPU-based rendering system for ray casting of multiple volumes. Our approach supports a large number of volumes; complex translucent and concave polyhedral objects as well as CSG intersections of volumes and geometry in any combination. The system (including the rasterization stage) is implemented entirely in CUDA; which allows full control of the memory hierarchy; in particular access to high bandwidth and low latency snared memory. High depth complexity; which is problematic for conventional approaches based on depth peeling; can be handled successfully. As far as we know; our approach is the first framework for multi-volume rendering which provides interactive frame rates when concurrently rendering more than 50 arbitrarily overlapping volumes on current graphics hardware.
