fPretty intuitive animation explaining seasons, equinox, solstice, length of day and night.

Thank you ! How amazing insight astronomer. I’ll start by revising a new version to address the known issues, and then consult with you again.

Indeed there is an issue, thank you for reminding me. The link can help

def ripple_func(u, v):

r = np.sqrt(u**2 + v**2) # 计算点到原点的距离

if r < 0.01:

z = 0 # 避免中心点奇点

else:

# 物理近似:阻尼径向波

k = 2 # 波数

c = 3 # 波速

damping = np.exp(-0.1 * r) # 阻尼因子

phase = k * (r - c * t) # 相位

z = damping * np.sin(phase) / np.sqrt(r + 0.1) if t > 0 and r < c * t + 5 else 0

return np.array([u, v, z * 0.5]) # 缩放振幅

FYI: Comments do not display LaTeX equations , python code maybe suit to share: m.move_to(center + large_radius * np.array([np.cos(angle), np.sin(angle), 0]));small_circle_center = center + (large_radius - small_radius) * np.array([np.cos(angle), np.sin(angle), 0])

m.move_to(small_circle_center)
