我正在编写一段代码,用来可视化四个符号在空间中的移动。目前,mayavi窗口显示初始位置,但不会更新到下一个位置。
#Library decleration
import numpy as np
from mayavi.mlab import *
....
#Inputting the intital positions into the storage vector
storage_position[0].append(v_1.theta)
storage_position[1].append(v_1.phi)
#Calculating the rest of the positions using the symmetry given
storage_position = Sym(storage_position)
#Plotting the intitial positions
x_coord = x_trans( storage_position)
y_coord = y_trans(storage_position)
z_coord = z_trans( storage_position)
plt = points3d(x_coord, y_coord, z_coord)
msplt = plt.mlab_source
@mlab.animate(delay=100)
def anim(storage_position, storage_vort, no_vort ,x_coord, y_coord, z_coord):
f = mlab.gcf()
while True:
#for i in range(10):
#Working out the hamiltonian
#Hami(storage_position, storage_vort, 1 - 1, no_vort-1)
transfer_vector = method(storage_position, storage_vort, 1 - 1, no_vort-1)
storage_position[0].append(transfer_vector[0])
storage_position[1].append(transfer_vector[1])
storage_position = Sym(storage_position)
x_coord = x_trans( storage_position)
y_coord = y_trans(storage_position)
z_coord = z_trans( storage_position)
msplt.set(x_coord = x_coord, y_coord = y_coord, z_coord = z_coord)
yield
anim(storage_position, storage_vort, no_vort - 1,x_coord, y_coord, z_coord)
mlab.show()x_coord等是numpy向量,用于存储四种符号的x坐标。x_trans等是为动画的每一步更新每个矢量的新坐标的函数。

试图替换这一行:
msplt.set(x_coord = x_coord, y_coord = y_coord, z_coord = z_coord)在这方面:
msplt.set(x=x_coord, y=y_coord, z=z_coord)点集数据源(应该是MGlyphSource类型的对象)知道x、y和z,但是x_coord、y_coord和z_coord不支持作为关键字参数。
下面是一个让您开始的完整的工作示例:
from mayavi import mlab
from numpy import array, cos, sin, cos
x_coord = array([0.0, 1.0, 0.0, -1.0])
y_coord = array([1.0, 0.0, -1.0, 0.0])
z_coord = array([0.2, -0.2, 0.2, -0.2])
plt = mlab.points3d(x_coord, y_coord, z_coord)
msplt = plt.mlab_source
@mlab.animate(delay=100)
def anim():
angle = 0.0
while True:
x_coord = array([sin(angle), cos(angle), -sin(angle), -cos(angle)])
y_coord = array([cos(angle), -sin(angle), -cos(angle), sin(angle)])
msplt.set(x=x_coord, y=y_coord)
yield
angle += 0.1
anim()
mlab.show()注意,当您运行这个程序时,您可能会看到大量的警告被打印到控制台上。忽略它们:它们是无害的,是已知问题。
