Hey everyone, I hope you've enjoyed the course I've made, had a lot of fun making it! :)

[EminTuralic]

What a blessing - I'm learning OpenGL currently and it's hard to find self-consistent sources. Thank you so much.

[anasssoulimani]

No way, I start this semestre with C++, you guys put an oop video. I start UML before Java and you guys put an UML video. My teacher asks me to create an-ecomerce website and you guys put the same thing. And now I'm on holiday, I start watching brian will videos on opengl and you guys post this.Thanks a lot!!❤❤❤❤❤❤❤❤

Good luck to you all and thx to the creator for this course <3

[radshiba_]

This course is super useful, my only issue has been that the footage is sped up so much to the point where I have trouble following along with the video at 0.25x speed. It gets pretty frustrating. Aside from that, I'm learning a lot though!

[TheMrInnokenty]

I’ve started an SDL course a week ago, and here’s OpenGl. That’s just perfect 👌🏽

[TheVideoChatter]

I've been searching for ways to learn C++ graphics rendering and then you go and upload my solution. Just what I needed today, thank you so much!

[matteo_mcguinness]

Literally what I wanted to learn. How am I so lucky?

[mattstopa]

Excellent lecture. I at first had a hard time with the accent but the way things were explained was so good that I got it!

[EL-cbnu]

I guess a lot of people have started building their own graphics engines during pandemic haha. Nice video!

[jeanjacquesstrydom]

This is an absolutely awesome tutorial, thank you so much for making it! I just wish people would make more OpenGL tutorials that are a bit more cross-platform, rather than just always focusing on Windows

[moccadocca]

OMG I've been looking around for good OpenGL courses. Perfect timing!

[industrialdonut]

this is crazy high quality like I'm actually able to follow along with almost no problems so far

[BangMaster]

This was so awesome. I love you guys for giving us free education. Please if possible, make a course on developing a video game using OpenGL

[thebeaverkidd]

You plus the OpenGL/C++ 3D Tutorial by Suraj Sharma combined has helped me learn a lot really quickly for starting to do a 3d game.
The only thing I feel like you could have touched on is Resizing the window which i later on found out I could to by changing the width and height from 'const static int' to just 'int' and then in the while loop do this:
glfwGetFramebufferSize(window, &width, &height);
glViewport(0, 0, width, height);
camera.Matrix(45.0f, 0.1f, 100.0f, shaderProgram, "camMatrix", height, width);

I added int height and width to the camera::matrix function in Camera.cpp and .h to update the camera size or else everything just stretched whenever I resized the window
but for anyone else experiencing this issue here you go : )
(oh yea, you also need 'glfwWindowHint(GLFW_RESIZABLE, GL_TRUE);' by all the other glfwWindowHint's for resizing)

[gabegonzalez]

Thanks for the tutorial. 99 percent of all my problems were self inflicted typos in the shaders. Spent forever trying to fix a lighting issue only to find out I had a comma instead of a period in one of the floats. lol Thanks again!

[tappingrat]

BEST course ever! Thanks man, thanks to you I'll pass my college!

[Kapalatus]

You had me at "You can show that window to your imaginary friends"....

[ConspiracyCraftersStudio]

Its a bit too fast delivery for a beginner but i've managed after 5 hours of following the tutorial to code spinning, textured pyramide. If you could explain and code it slower it would be one of the best opengl tut on youtube. Its still very good! Gonna build my simple render/game engine based on this project. Much appreciated
