基于Ray-casting算法的并行存储系统
Ray-casting算法 低位交叉并行存储系统 页模式
2009/8/10
Ray-casting算法是一种高质量的直接体绘制算法，但绘制速度过慢，因此设计基于Ray-casting算法的硬件专用体系结构已成为研究的热点。而存储系统又是制约整个体系结构的瓶颈部件，其性能的优劣直接影响整个系统的运行速度。该文针对直接体绘制中的Ray-casting算法设计了无访存冲突的八体低位交叉并行存储系统VOXMEM提高吞吐率，并提出相应的体素存储分配策略和地址计算方法。该并行存储系统...
An iterative programmable graphics process unit based on ray casting approach for virtual endoscopy system
virtual endoscopy linear interpolation
2011/5/6
In this paper, a fast graphics process unit (GPU) based ray casting algorithm is presented to improve image quality. A linear interpolation is used to estimate the intersection between a ray and isosu...
View Dependent Layer Sampling: An Approach to Hardware Implementation of Volume Ray Casting
