【摘要】 提出了一种基于快速区域标识的交互式体切割算法.在进行切割计算时采用了一种有效的体数据空间标识算法,该方法具有和切割形状无关的特性,可精确地按照用户定义的任意形状对体数据进行切割.同时,还利用基于三维纹理映射的通用图形硬件加速体绘制算法对切割结果进行绘制,该方法在普通PC上可有效地对体数据进行交互式切割.更多还原

【Abstract】 A novel interactive volume clipping method based on region marking is proposed.The method uses an efficient dataset region marking algorithm to archive the interactive result,regardless of the shape of the clipping object to define which parts of the volume have to be clipped.The proposed technique is integrated into the general graphics hardware accelerated volume rendering.The sophisticated graphics hardware is utilized to make it possible to interactively select and explore regions of the volume datasets under the standard PC.更多还原
