Kuen Surface应该又是一个以数学家名字命名的曲面.
本文将展示几种Kuen Surface的生成算法和切图,其中有的是标准的,有的只是相似.使用自己定义语法的脚本代码生成数学图形.相关软件参见:数学图形可视化工具,该软件免费开源.QQ交流群: 367752815
公式1
#http://jalape.no/math/kuentxt vertices = D1:100 D2:100 u = from (-4.5) to (4.5) D1 v = from (PI*0.01) to (PI*0.99) D2 x=2*(cos(u)+u*sin(u))*sin(v)/(1+u*u*sin(v)*sin(v)) z=2*(sin(u)-u*cos(u))*sin(v)/(1+u*u*sin(v)*sin(v)) y=log(tan(v/2))+2*cos(v)/(1+u*u*sin(v)*sin(v))
