Importing the geometry character of the triangular mode by the right-hand rule; 对圆形区域法进行改进,以右手螺旋法则构造三角形模式的几何特征;
The author proposes a 3D triangular mesh simplification algorithm with the method of vertex culling, which is based on the rule of vector angle. 提出以顶点向量夹角为剔除准则,运用顶点去除方法进行网格简化的算法。
The full-overlapped triangular normal subordinate function has been adopted as the input variable in the type fuzzy controller and the PID expressions is selected in the rule consequences. The TS-PID fuzzy controller is investigated to be a class of nonlinear PID controllers in essence. 该类模糊控制器的输入变量采用正规模糊集、三角形全交迭隶属度函数,规则后件采用PID表达式,其本质为一种非线性PID控制器。
