Drivers/Vpython visualizations/examples?

[DarkSky7]

I looked at demo/python/astronomy.py - huge piece of code, but no main. Where can I find test driver examples? Are there plans for Vpython visualizations or existing examples to read?

Hi @DarkSky7 and welcome to the project!

If you are looking for the unit tests to see how the Python version of Astronomy Engine is validated, there is a bash script unit_test_python which runs pylint and mypy, then invokes the main test script test.py. It also generates a large output file exercising the core functionality for comparing the calculations with the other programming language implementations for consistency.

If you are looking for sample programs, there is a collection of demos that are all console-mode programs.

About VPython, I had to look that up... it is new to me. It does look very interesting! So no, I didn't have any plans for that. I'm trying to understand if VPython is open source, and if so, where I can find the source code.

Vulkan might do the trick too; it's newer and faster than OpenGL (upon which Vpython 'rides'). On the examples, I was looking for something 'simple' (a lot less than 10k lines) that I could learn from, maybe specify a UTC datetime and get back the state vectors of solar system objects - sun, planets, planetessimals, moons, major asteroids, comets, ... (whatever I can get).

It's been around a long time, I saw nothing about licensing on: https://vpython.org/index.html https://vpython.org/contents/developers.html says it's open source.
