[vispy viewer] investigate if we can record a video of the rotating image

[sanjayankur31]

We can manually rotate the cell at the moment, but it isn't ideal---it rotates about its original position. But, what will be great is if a key would allow the user to record a video of whatever is being shown in the viewer. They can then pan and zoom etc. to easily create a visualisation of their network.

It should be already doable:

vispy/vispy#1979

Can also be done using moviepy, but it's currently struggling with lack of maintainers, so let's maybe not use it just yet.

Hello sir @sanjayankur31. I would like to work on this issue. I will update you after I go through all the instructions mentioned thoroughly.

Hi sir @sanjayankur31
to solve this issue i am thinking of writing a code where

• I am importing the imageio library, which will be used for video recording functionality.

• I am setting up a scene canvas with various customization options, including cameras,
  coordinate axes, and video recording functionality.

• I will create_new_vispy_canvas function that takes arguments to customize the view range,
  title, coordinate axes, and color theme.

• I am creating and configuring multiple camera objects (PanZoomCamera, TurntableCamera,
  ArcballCamera, and FlyCamera) for different viewing perspectives.

• I am adding event handlers for key presses to control video recording using the
  imageio library.

• I am defining functions for updating the visualisation, toggling video recording,
  and rotating the view.

• I will create a function plot_interactive_3D to create an interactive 3D visualisation.

Is this approach good to start with? Would be grateful for your guidance.
