Abstract: :The principal advantages of direct volume-rendering techniques over other visualization methods are their superior image quality and the ability to generate images without explicitly defining surface geometry.The principal drawback of these techniques is their cost.Since all voxels participate in the generation of each image,rendering time grows linearly with the size of the dataset.This paper presents a adaptive binary-volume pyramid-based volume-rendering algorithm,in which volume rendering is generated quickly without lowing image quality.
摘要: 直接体绘制技术无需拟合中间几何图元直接绘制体数据,由于绘制图像质量高,该技术倍受青睐。但是,因为直接体绘制需要遍历整个数据场,绘制速度慢,在绘制大规模数据场时,速度已经成为应用该项技术的一大瓶颈。为此,本文提出一种基于二值体金字塔数据结构的自适应快速体绘制方法,该方法可以在不降低图像质量的情况下,加快图像绘制速度。
