我们现在已经可以在一台桌面计算机上利用三维数组中的数千个节点证明该理论，但要完全实现需要百万计的细胞或者同等当量的计算。
P. on a desktop computer using thousands of nodes in a 3-d array, but a good calculation requires millions of cells or the equivalent.
现在所有的桌面三维打印软件均源自一个名叫RepRap的项目，该项目是英国巴斯大学的艾德里安·波耶教授及其同事开发的。
The grandaddy of all desktop 3D-printers is the open-source RepRap project conceived in 2005 by Adrian Bowyer and colleagues at the University of Bath, in Britain.
当然，家庭使用的三维打印机也有不足，使用桌面三维打印机制能制作出五立方英寸（12立方厘米）大小的产品；不足工业用三维打印机能够制作的产品尺寸的六分之一。
There are drawbacks, of course. The size of products that can be made using a desktop 3D printer is usually limited to something that can fit within a five-inch (12.7cm) cube.
提出一个桌面虚拟环境下的笔式三维交互框架，包含交互原语和交互任务构造两个核心组件。
Including two main components for generating interaction primitives and interaction tasks, an architecture for pen-based 3D interaction in desktop virtual environment is proposed.
