摘要
研究了测量计算机绘图软件中非标准几何体尺寸的问题。首先阐述了利用绘图软件对非标准几何体的预处理方法,然后根据各种几何体的特性及插值理论,推导出了测取绘图软件中非标准几何体尺寸的"取点法",并以计算机绘图软件中的三个几何体为例,对该方法进行了验证,其结果表明了此种方法的可靠性。
The problem of measuring the size of unstandard geometric form in computer graphics software is studied. Firstly, the method of pretreating unstandard geometric form is described. Then on the basis of the features of the geometric forms and the interpolation theory, the points-selecting method is presented which can measure the size of unstandard geometric form in graphics software. The proposed method is applied to three geometric forms in computer graphics software. The results prove that the simulation is creditable.
