如何在Python中以3D方式绘制图像？

Question

Inserting an image into a 2d chart using Python has been answered here ... how do I do this in 3d? Looking for something like this (image comes from a MATLAB example )...

Answer 1

I don't think that's how plotly has designed the image insertion, its more of adding a background image to the plot. Please refer the below example of what can be achieved using images property of layout object. To know more read here

import pandas as pd
import numpy as np
import plotly.plotly as py

x, y, z = np.random.multivariate_normal(np.array([0,0,0]), np.eye(3), 200).transpose()
trace1 = go.Scatter3d(
    x=x,
    y=y,
    z=z,
    mode='markers',
    marker=dict(
        size=12,
        line=dict(
            color='rgba(217, 217, 217, 0.14)',
            width=0.5
        ),
        opacity=0.8
    )
)

x2, y2, z2 = np.random.multivariate_normal(np.array([0,0,0]), np.eye(3), 200).transpose()
