摘要
三视图是画法几何教学中的难点和重点。该文分析了正等侧投影模式下的三视图投影原理,提出了利用随机产生的3×3×3小立体单元堆叠构造空间立体对象的方法,并给出了空间立体的数学模型及其三视图生成算法,最后基于该算法实现了一个用于CAI教学的三视图视图训练系统。
view is difficulty and emphasis in descriptive geometry teaching.The theory of 3-view projection is discussed in this paper,a method of using 3x3x3 random created small three-dimensional units to construct the space object is put forward,the mathematic modal of space object and its 3-View Creation algorithm is given also,a 3-view teaching system based on this algorithm is achieved eventually.
