Zeichnen Sie einen Torus mit Python ⇐ Python

[Anonymous]

Ich bin neu in Python und versuche, einen Torus zu zeichnen. Ich möchte, dass mein Torus wie Torus aussieht, aber mein folgender Code funktioniert nicht.import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D

# Parameters for the torus
R = 2 # Major radius
r = 1 # Minor radius

# Create a meshgrid for u (angle around the main circle) and v (angle around the tube)
u = np.linspace(0, 2 * np.pi, 100)
v = np.linspace(0, 2 * np.pi, 50)
u, v = np.meshgrid(u, v)

# Parametric equations for the torus
x = (R + r * np.cos(v)) * np.cos(u)
y = (R + r * np.cos(v)) * np.sin(u)
z = r * np.sin(v)

# Plotting
fig = plt.figure(figsize=(8, 6))
ax = fig.add_subplot(111, projection='3d')

# Torus surface
ax.plot_surface(x, y, z, rstride=1, cstride=1, color='lightblue', edgecolor='gray', alpha=0.6)

# Add lines of latitude (constant v, varying u)
for j in np.linspace(0, 2*np.pi, 12): # meridians
x_line = (R + r * np.cos(j)) * np.cos(u[0])
y_line = (R + r * np.cos(j)) * np.sin(u[0])
z_line = r * np.sin(j) * np.ones_like(u[0])
ax.plot(x_line, y_line, z_line, color='darkblue', linewidth=1)

# Add lines of longitude (constant u, varying v)
for i in np.linspace(0, 2*np.pi, 12): # parallels
x_line = (R + r * np.cos(v[:, 0])) * np.cos(i)
y_line = (R + r * np.cos(v[:, 0])) * np.sin(i)
z_line = r * np.sin(v[:, 0])
ax.plot(x_line, y_line, z_line, color='darkred', linewidth=1)

# Set aspect and remove axes
ax.set_box_aspect([1, 1, 1])
ax.axis('off')
plt.title("Torus with Parallels and Meridians")
plt.show()< /code>

Wie kann ein Torus auf diese Weise zeichnen? Vielen Dank im Voraus.
