ray casting

基本解释

Ray casting were stared out at every pixel on screen along viewpoint direction, and then some sample points were selected on the line.
其光线投射算法从屏幕上的每个像素点出发，沿设定视点方向，发出一条射线，沿该射线选择若干个等距采样点。
Sufficient experimentation shows that we could reach a good frame rate and a satisfied image quality, which could be compared to the result of ray casting.
充分的实验结果表明本文的算法达到了和传统光线投射算法相媲美的图像质量和相当高的绘制速度。
A novel method for 3D visualization with improved image quality and speed has been developed by closely combined use of image processing, ray casting and bounding box technology.
把图像处理、光线投射与包围体技术有机结合，提出了一种提高成像质量和速度的三维可视化新方法。
