1一种用于实时体绘制系统的自适应采样算法显示文摘本文讨论了一种用于体绘制的、支持基于空间跳跃和自适应光线终止等优化算法的高效硬件结构及一种加速半透明物体绘制的新技术 .这种硬件结构用于绘制规模为 2 5 6 3 体元的数据时可达到 70Hz的帧频 ,但这样的帧频只是在体元的透明度都被置为 0 (完全透明 )或 1(完全不透明 )的情况下才能取得 .引入新的加速技术后 ,绘制半透明物体的帧频也可接近上述数值 .新的加速技术采用自适应采样步长减少体绘制过程中冗余的体元重采样 ,从而使算法的复杂度和对存储器的带宽要求大大减小 .新的加速技术对半透明体数据可取得高达 4 7倍的加速比 .采用新的加速技术需要在开始交互绘制前对体数据进行距离编码 .优化后的距离编码对有 8兆体元的体数据的预处理时间仅需要 8~夏放怀 沈振康 唐朝京 谌海新 Juergen Hesser Bernd Vettermann Reinhard Mnner 2002电子学报2002,30,3:3
