介绍了一种基于构造立体几何（CSG）的三维形状建模系统，该系统支持直接、交互式的形状建模过程。该功能通过体素模型实现实时集合操作，体素模型的体扫描显示实现体素模型的直接可视化，以及数据结构管理的CSG模型实现。体素模型上的集合操作可以通过简单的位计算来执行，因此可以实时创建所设置对象的体素数据。体元扫描显示器是显示体元数据的合适设备。不需要进行密集的计算来显示所设置的对象。体积扫描显示器可以提供精确的3d图像，不需要护目镜或眼镜。这个概念在实际的建模环境中应该是有用的
A newly developed 3-D shape modeling system based on constructive solid geometry (CSG) is described, in which a direct and interactive shape modeling process is supported. This feature is realized by a voxel model for real-time set operations, and a volume scanning display for the direct visualization of the voxel model, besides the CSG model for data structure management. The set operations on the voxel model can be executed as simple bit calculations, and therefore, the voxel data for the set object can be created in real time. The volume scanning display is a suitable device for presenting the voxel data. There is not need for intensive calculations to display the set objects. The volume scanning display can provide exact 3-D images without goggles or glasses. The concept should be useful in an actual modeling environment.<<ETX>>
