如何平滑Plotly 3d曲面图？

import plotly.graph_objects as go
import numpy as np

# 生成坐标轴上的点
x = np.linspace(-5, 5, 100)
y = np.linspace(-5, 5, 100)

# 生成网格
X, Y = np.meshgrid(x, y)

# 计算Z值
Z = np.sin(np.sqrt(X**2 + Y**2)) / (np.sqrt(X**2 + Y**2))

# 创建曲面图
fig = go.Figure(data=[go.Surface(x=X, y=Y, z=Z)])

# 调整曲面参数
fig.update_traces(contours_z=dict(show=True, usecolormap=True,
                                  highlightcolor="limegreen", project_z=True))

# 添加颜色映射
fig.update_traces(colorscale="Viridis")

# 调整光照效果
fig.update_layout(scene=dict(annotations=[], aspectratio=dict(x=1, y=1, z=0.7),
                             camera_eye=dict(x=1.2, y=1.2, z=0.6)))

# 显示曲面图
fig.show()
