OpenGL with PyOpenGL Python and PyGame p.2 - Coloring Surfaces

In this tutorial, we learn some more of the basics of OpenGL using PyOpenGL, which is a Python module for working with OpenGL, along with using PyGame, which is a popular gaming module for Python. PyOpenGL works with many other Python modules as well. In this example, we work on how to program a 3D cube, adding colors to the surfaces. We also learn a bit more about how OpenGL works on the back-end.

FYI (and for others that where equally as confused as I was) with the vertices you have defined node 7 and 8 on the figure you displayed are actually swapped. I know this because I mapped the cube in paint, and the fact that the two squares had a different pattern greatly confused me until I realized it was because of the vertices definition. *This happened because you broke the rule of only changing 1 of the 3 values at the same time in the previous video* :P

The pattern after the definition is actually
1-2
4-3
and second square is
5-6
7-8

Simply changing node 7 and 8 values should make the same pattern, but that also means changing all the edges. Or you could alternatively just not give a crap that they are listed in the wrong order.

Hello, sorry I wanna ask. I am still confused why for the color, you declare in 12 times, while the surfaces only 6. Thank you

How could I also rotate my cude around another axis? So, simultaneously the cube will be rotated around its axis and around another relative axis. In case you need I can send the code

[chinmayapurohit]

how do you make sure that the two triangles have only one colour? Like..One colour per surface?

[profskitty]

Would you be able to recommend a way to put sprites for a HUD in OpenGL mode?

I'm from 7 years in the future ... you can use color names as a string now instead of using values - "red" "blue" "green" e.t.c.

for (color, surface) in zip(colors, surfaces):

does it makes sense to watch this in 2021?

what does x=0 and x+=1 mean? what do they related to?
