A three-dimensional computer modelling system has been developed for use in biology, and is currently running on a Sun3 computer. The data originate as a series of two-dimensional micrographs which are digitised via a TV camera. The two-dimensional images are used to select features of interest and to construct a three-dimensional model. This model can be viewed in vector or solid format, it can be rotated about three orthogonal axes and can be viewed in three dimensions as a stereo pair or an anaglyph. The system has been used in a large number of projects over the past 10-15 years, for example, to examine physiological and nerve structures. The time-consuming part of the process is the selection of features, which involves a high level of biological expertise. Present developments are concerned with reduction of the time spent in feature recognition and involve the introduction of expert systems together with human-computer interaction to deal with problems of identification.
已开发出一种用于生物学的三维计算机建模系统，目前在Sun3计算机上运行。数据源自一系列通过电视摄像机数字化的二维显微照片。二维图像用于选择感兴趣的特征并构建三维模型。该模型可以以矢量或实体格式查看，可以绕三个正交轴旋转，并且可以作为立体对或互补色立体图以三维方式查看。在过去10到15年中，该系统已用于大量项目，例如检查生理和神经结构。该过程中耗时的部分是特征选择，这需要高水平的生物学专业知识。目前的进展涉及减少特征识别所花费的时间，并涉及引入专家系统以及人机交互来处理识别问题。
