摘要 随着三维数据场可视化精度要求的不断提高,直接体绘制方法已经成为该领域的研究热点。然而,提高数据场采样率以获得高质量的图像与绘制速度的降低这一矛盾,很大程度上限制了体绘制方法的研究进展。论文阐述了体绘制方法的关键技术——分类和体绘制积分,并在此基础上介绍了预积分分类技术。该方法能够同时提高体绘制方法的执行效率与图像质量,并给出了实例说明。最后,提出了预积分分类技术中存在的一些问题。 Volume rendering methods have been the active research area since it's the ability of visualizing the inner structure of 3D volume data.However,the trade-off between the rendering speed and acquiring high-quality rendered images because of the increasing of sampling rate restricts the further development of direct volume rendering methods. The paper introduces the pre-integrated classification technique on the basis of expatiating the classification and volume rendering integration.The pre-integrated classification has the potential to improve the accuracy and the performance of the volume renderer at the same time.In the end,some examples and advices for pre-integrated classification technique are given.
