ray cast meaning in English
光线投射
Examples
- unlike ray casting, where each image pixel is built up ray by ray, this approach takes advantage of spatial coherence
但与光线投射算法不同的是,此算法利用空间信息对穿过同一切片的所有光线同时处理。 - analysis and implementation of volume rendering based on ray casting the related work includes algorithm principle, implementation pipeline and accelerated techniques
基于光线投射的体绘制算法的分析与实现研究内容包括算法原理、流程步骤和优化技术。 - 3 . presenting a medical visualization testing system this system adopts the volume rendering based on ray casting algorithms and also makes the use of the traditional surface rendering method
实现了一个医学可视化试验系统该系统主要采用了体绘制的光线投射算法，也用到了传统的面绘制算法。 - secondly, we analyses the volume rendering based on ray casting, includeing algorithm principle, implementation pipeline . and for the features of medical slice images, improved trilinear interpolation algorithm is presented with an increase of the speed ray-casting in direct volume rendering
其次,详细分析了光线投射体绘制算法的基本原理、流程步骤,并针对医学断层图像的特点,提出和实现了改进的三线性插值算法,从而大大提高了光线投射法的绘制速度。 - we combine the algorithm of ray casting and z-buffer to rebuild 3d data, and use marching cubes to create iso-surfaces in 3d regular data sets . several common spatial interpolation are discussed in this thesis, and the famous kriging algorithm in the geological statistics is the emphasis .-four interpolations are used in the case of study, and the results are compared in this thesis
在系统实现中，针对两类算法的不同特点，在不同的模块中选用了两类算法中的经典算法：提出将光线投射法与z-buffer算法结合实现三维体数据重建；使用移动立方体法实现三维数据场的等值面绘制。
