数学图形(2.20)3D曲线

这一节主要是发布我自己写的3D曲线,

(1)立体flower线圈

vertices = 8000
a = 10.1
b = 3.1
s = (a + b) / b
o = 4

i = from 0 to (40*2*PI)
j = mod(i, 2*PI)
k = mod(s*i, 2*PI)

m = a*sin(j)
n = a*cos(j)

x = m + o*sin(k)
y = n
z = o*cos(k)

(2)乱

vertices = 12000

t = from (0.0) to (100*PI)

r = 10

a = rand2(PI*0.1, PI*0.9)

s = sin(t)
c = cos(t)

x = r*s*cos(t/sin(a))
z = r*s*sin(t/cos(a))
y = r*c
