Cool rendering

I havent posted any devlogs lately since my account had an issue with time sync.
Now I am back, here are the features that i added:
-Improved rendering pipeline
-Made a foundation for the final project
-Added basic shading
-Tested the transformation

It finaly starts to look like something:

I made a function that draws sphere in OpenGL, It took me a lot of calculations. I added a shader from the internet, it looks terrible, but i leats i know that the sphere is ok:

I made a function that draws circles in OpenGL, now i will work on making spheres.

I learned how to use index buffer

Learned the basics of openGL
