I'm a newbie and a muscician and I want to programm a live python midi interface to visualize my favourite song when I play it on my keyboard. I've started learning python, installed Ubuntu, configured my environnement and searched for online libraries. I found here <https://wiki.python.org/moin/GuiProgramming> those libraries: *-pygame-pyglet-pyopengl*My purpose was to use pygame's midi librairies to listen to my keyboard and use pyopengl for the graphics. The problem was that I didn't found anywhere sufficient documentation for learning pyopengl and I gave up until I discovered Piglet! I'm not sure if I can implement the pygame's midi library and integrate it with piglet. Is this possible? or should I use pygame with pyopengl instead? My question is : *Can I use piglet to programme my app with pygame's midi library?* *What I want to do:* Here is an animation more or less simillar than my idea ( I only want 12 sectors and of course map it with my midi keyboard) https://www.youtube.com/watch?v=4kkNbtbWbm8 First step, I want to draw a circle with sector like this (in 2d or 3d) <https://fr-images.tuto.net/tuto/thumb/648/288/49140.jpg> But first thing first, I started with hello world and then writed a simple app who draw a circle (https://www.youtube.com/watch?v=dEZDPjVegT4) But then, I want to do this shape with 12 sectors and I don't know how to proceed. I looked for the GL_POLYGON method but I don't know how to implement it. Can someone help me with a basic example or procedure to follow? *(for instance :* 1. *make an array with all vertices * 2. *draw a polygon shape with GL * 3. *fill it * 4. *change the camera projection* 5. *etc...* *)* I'm motivated to learn piglet, opengl and python but I seek for ressources, example and support Sorry for my bad english I'm not native.
