数学图形(2.19) 利萨茹3D曲线

在前面的章节数学图形(1.13) 利萨茹曲线中,写的是二维的利萨茹曲线,这一节,将其变为3D图形.

vertices = 12000

a = rand2(1, 10)
b = rand2(1, 10)
c = rand2(1, 10)

k = rand2(0.2, 5)
n = rand2(0.2, 5)
m = rand2(0.2, 5)

t = from 0 to (80*PI)

x = a*sin(k*t)
y = b*sin(n*t)
z = c*sin(m*t)

 

看上去就是几团乱麻.有时看代码时就像这种利萨茹3D曲线,看上去有点规律,却又觉得思绪太乱.

不同参数下的利萨茹3D曲线:

k = 3
n = 2
m = 7

k = 4
n = 3
m = 5

k = 3
n = 4
m = 17

k = 3
n = 5
m = 22
