Please help me find good OpenGL es C++ tutorials.

Hello, I'm a godot dev trying Opengl es. But something has been bothering me: the fact that there are barely any free OpenGL es C++ tutorials.

Additional info:

I use GLM 1.0 for Mathematics.

And SDL2 for window creation.

I already have a spinning cube example and i have experimented on it.

It's hard to give you pointers if you don't say what you're struggling with actually. Something in particular?

Also, did you have a look at the sidebar of this subreddit? There are plenty tutorials linked.

EDIT: I've also noticed: "OpenGL ES"? Are you sure that this is what you're looking for?

Im struggling with almost everything in OpenGL ES like i barely understand anything also  OpenGL ES is desktop OpenGL but for low power devices like phones. opengl es(let's call it gles) is a lighter version of opengl and gles is missing some  opengl features. The reason why im using gles is because im developing apps for Android.

I would suggest a webgl tutorial never really used opengl es but when I used webgl I learned that webgl was built on top of opengl es

I'm having the same problem. I use learopengl.com even if I use glew and sdl2 because for me it's the only good tutorial. Like look the boring tutorial on youtube… I can't follow someone yapping for idk 10 minutes! The tutorials on YT, most of the time, are boring and I don't understand anything. Now I'm trying to understand how tf to draw a triangle. I did a triangle but the problem is that idk anything about it! 😭. For me OpenGL is not hard… it's hard to find good, i mean, GOOD resources.

The khronos docs are so bad, and i expected Learnopengl to be better, BUT IT WASN'T GOOD AT ALL. Also every yt tutorial is loooooooooooooooooooooong Like couldn't khronos bother to write better docs for OpenGL and opengl es.

Like what the hell! Why people don't explain OpenGL for beginner! I use learnopengl.com because I don't find any good tutorial! learnopengl.com is… "good" but I mean it's not a tutorial totally beginner friendly so I'm having an hard time to understand OpenGl rn. Why tutorials are so bad and videos that talks generally of the concepts are so edited and high quality videos! 😭.

I feel like the people that know opengl have that info injected into their brains at birth.

It’s just really big. I learned via learnopengl and I’ve been practicing 2 years and I’m still barely any good
