In this article, I will take you through an excellent technique to create a 3D video with python by using the matplotlib package. But before learning to create a 3D video with python, I would suggest you learn how to create 3D plots with python from here.
3D Video with Python using Matplotlib
First, I’ll create a simple 3D contour plot with matplotlib:

The code above will give you a digit without an axis because we are declaring axis3don = False. We cannot hide the panel and grid colour, but we can make it similar to the background image (white) as mentioned in the comment “# make the panel and grid colour “white”. The code will display the result like this:
A video is a collection of images. We are therefore going to create many images with different azimuthal axis viewpoints. We can adjust this:
# adjust point of view ax.view_init(60, 90)Code language: CSS (css)
Now, we need to change the value of 90 to a sequence number from 0 to 360 by using the code below:
You will get 180 images with different names, you can check it in Jupyter Notebook 3d directory by using the command below:
! ls 3d/
The names of the images are listed from 3d_vis_0.png to 3d_vis_358_.png. To combine them all, we need to create an array consisting of the names of figures, using the code below:
Then we combine all of that into a single video to create a 3D video with Python. The extension of the video is in GIF. You combine it using the code below:
# Create the frames frames =  files for i in files: new_frame = Image.open(i) frames.append(new_frame) # Save into a GIF file that loops forever frames.save('3d_vis.gif', format='GIF', append_images=frames[1:], save_all=True, duration=40, loop=0)Code language: PHP (php)
It will save to a GIF file named 3d_vis.gif that is 40 seconds long in a single loop. Here is the output of the modified 3D video. I just modified the angle and colour maps:
