How can I plot an image in Python in 3D?

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
