这一节文章中,将总结一些在圆柱面上的曲线.

之前的文章,它是圆柱与球相交而生成的曲线.

 

(1)crepe曲线

#http://www.mathcurve.com/courbes3d/crepe/crepe.shtmlvertices = 2000t = from 0 to (2*PI)a = 10 x = a*cos(t)y = a*sin(t)z = a*sin(2*t)

 

(2)Seam of a clinder

#http://www.mathcurve.com/courbes3d/couture/couture.shtmlvertices = 2000t = from 0 to (2*PI)a = 10x = a*cos(3*t)y = a*sin(3*t)z = a*sqrt(3)/2*sin(2*t)

 

(3)Tangentoidal crown

#http://www.mathcurve.com/courbes3d/couronnetangentoidale/couronnetangentoidale.shtmlvertices = 12000t = from 0 to (2*PI)a = 10b = rand2(1, 10)n = rand_int2(1, 20) x = a*cos(t)y = a*sin(t)z = b*tan(n*t/2)#z = limit(z, -50, 50)

这是帖在柱面上的tan曲线
