In the model , the overall atmospheric state at any given instant is represented by the values of the variables at systematically arranged points set up within a three - dimensional grid 模式内的大气三维空间被分割成为排列整的网格点阵,而各网格点上气象变数的数值则代表了当时大气的整体状态。
In the model , the overall atmospheric state at any given instant is represented by the values of the variables at systematically arranged points set up within a three - dimensional grid 模式内的大气三维空间被分割成为排列整齐的网格点阵,而各网格点上气象变数的数值则代表了当时大气的整体状态。
In some representative algorithms for the registration of multiple range images , the range image is only considered as a 3d point set . the motion parameters are estimated by matching the closest point in other range image 在现有的代表性的对准算法中,都是把距离图像看成3d点集,通过匹配不同距离图像之间的点对,估计运动参数。
This paper develops 3d graphics with opengl and draws three - dimensional entities visualization by spatial point set . thu three - dimensional effect and visualization of 3d entities figure are strengthened by light 摘要介绍了采用空间点集绘制实体的方法,生成真实感较强的三维实体图形的过程和三维实体的交互式旋转、缩放、多方位剖切等可视化显示。
Evolution equations defined on the point set of time are proposed , subsystems which have their own independent time standards are introduced , and a criterion for judging if consistency conditions emerge in subsystems are gotten as well 把内变量演化方程定义在时间点集上,引入了有自己独立时间标准的子系统结构,给出了在非耦合子系统中一致性条件成立的判别准则
