a visualization systems based on volume rendering algorithm is introduced at the end of the paper . it has the function to reconstruct 3d-images from 3d-regular data sets and has fine interactive capability 该系统能较好地演示对一些由ct、mri或组织切片等堆叠构成的数据场的重建,并具有一定的交互性。
the programmable gpu permits developers to write vertex shaders and fragment shaders running on it, to replace the fixed function pipeline, and to employ custom rendering algorithms 可编程图形处理器允许用户编写运行在其上的顶点着色程序与片断着色程序,取代内置的固定功能渲染流水线,实现定制的渲染算法。
with such fast development, many unresolved problems in the 3d visualization software find the new resolutions by support of many new rendering algorithms and computer techniques 随着医学图像可视化技术的不断发展,新的绘制算法和计算机技术的支持使过去的三维医学可视化软件存在的很多问题有了新的解决方案。
the visual display of the result data includes structural deforming graph, animation simulation, three dimension image, contour, isosurface and cloud map etc . in this paper, a volume rendering algorithms is discussed 在对这些数据的可视化表现可以分为结构变形图,结构受力动画模拟,三维图像,等值线,云图等。
according to the data characteristics of mineral resources exploration, this paper has studied the volume rendering algorithm model and the spatial interpolation method suitable for 3d visualization of geological information 摘要针对矿产资源勘探数据的特点,研究了适合地质体信息三维可视化的体绘制模型和空间插值算法。
