数学图形(1.40)T_parameter

不记得在哪搞了个数学公式生成的图形.

vertices = 1000



t = from 0 to (2*PI)

r = 2.0

x = r*(5*cos(t) - cos(6*t))

y = r*(3*sin(t) - sin(4*t))

给线加上一维变量的变化,使之变成面:

vertices = D1:360 D2:21



u = from 0 to (2*PI) D1

v = from 0 to 20 D2



x = (v+2)*cos(u) - cos((v+3)*u)

y = v*sin(u) - sin((v+1)*u)
