高效绘制多个球体

不,没有“球体艺术家”这样的东西。即使有,也不会花更少的时间来绘制它。

u = numpy.linspace(0, 2*numpy.pi, 12)
v = numpy.linspace(0, numpy.pi, 7)

not actually been designed for it ; 和使用 Mayavi 相反 上面在mayavi的图片看起来像

from mayavi import mlab
import numpy as np

[phi,theta] = np.mgrid[0:2*np.pi:12j,0:np.pi:12j]
x = np.cos(phi)*np.sin(theta)
y = np.sin(phi)*np.sin(theta)
z = np.cos(theta)

def plot_sphere(p):
    r,a,b,c = p
    return mlab.mesh(r*x+a, r*y+b, r*z+c)  


for k in range(200):
    c = np.random.rand(4)
    c[0] /= 10.
    plot_sphere(c)

mlab.show()

虽然计算需要相似的时间,但在Mayavi中交互缩放或平移要快得多。

points3d

from mayavi import mlab
import numpy as np

c = np.random.rand(200,3)
r = np.random.rand(200)/10.

mlab.points3d(c[:,0],c[:,1],c[:,2],r)

mlab.show()
