Questions regarding the unit visual #1

Hi Zámečník,

Sorry to send you a question in the issues section. I'm trying to find codes to get the rotation minimizing frames to work with my 3d space curves as a demonstration to my students. I run into your code here and it looks promising. However, I wonder if you may tell me where is this visual library? For example, from visual import vector

Is visual the vpython library? Thank you.

Hi @Thompson104, yeah it was https://vpython.org/. Check its documentation for installing it. If you manage to run it I'll be wondering how it works for your lesson.

Hi Zámečník,

I'm interest in using your code as well. However, I'm having trouble to run the code with Python 3.8.3. I installed vpython 7.6.2, and replaced visual with vpython as below (following https://stackoverflow.com/questions/28592211/importerror-no-module-named-visual) and in the script:

import time, math, vpython
from vpython import vector

Now, I get the following error message:

    vpython.scene = vpython.display(width=800, height=800)
AttributeError: module 'vpython' has no attribute 'display'

Any suggestions to get you code running in the updated Python 3 and vpython 7?

Thanks,
