Real-time volume rendering
We present Cube-4, a special-purpose volume rendering architecture that is capable of rendering high-resolution (e.g., 10243) datasets at 30 frames per second. The underlying algorithm, called slice-parallel ray-casting, uses tri-linear interpolation of samples between data slices for parallel and perspective projections. The architecture uses a distributed interleaved memory, several parallel ...
متن کاملTowards Real Time Volume Rendering
The task of real time rendering of today’s volumetric datasets is still being tackled by several research groups. A quick calculation of the amount of computation required for real-time rendering of a high resolution volume puts us in the teraflop range. Yet, the demand to support such rendering capabilities is increasing due to emerging technologies such as virtual surgery simulation and rapid...
متن کاملReal-Time Programmable Volume Rendering
Real-time graphics hardware is rapidly becoming programmable, and has recently incorporated the features needed for direct volume rendering. Unfortunately, the standard interfaces to this hardware are at the assembly language level. When programming at this level, it is difficult re-use and modify existing implementations of volume rendering algorithms, and it is extremely tedious to experiment...
متن کاملReal-Time Volume Rendering for Virtual Colonoscopy
We present a volume rendering system that is capable of generating high-quality images of large volumetric data (e.g., 512) in real time (30 frames or more per second). The system is particularly suitable for applications that generate densely occluded scenes of large data sets, such as virtual colonoscopy. The central idea is to divide the volume into sets of axis-aligned slabs. The union of t...
متن کاملParallel Considerations for Real-time Volume Rendering
Current technology dictates that parallel processing is required to perform real-time volume rendering for any signi cant data set sizes and image qualities. This paper compares parallel architectures and algorithms which perform volume rendering, as well as a few alternative architectures not previously applied to the volume rendering problem. Since the memory to processor bandwidth is the maj...
