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
Thank you! Sadly it would be quite a bit more work to translate it to the other OSs and then also check if it works properly on them, and I just don't have that kind of time right now in university...

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)
This is genuinely the best programming tutorial i think i have ever seen in my life. you really saved me with this, and i feel like i actually understand everything that went into doing this. cant thank you enough for this amazing course
This tutorial video was definitely eye-opening & insightful, I've read about OpenGL & DirectX game dev, but nothing really stuck /w me. This course video really shed some light on it. Thank you, I appreicate it !! 😎
PLEASE REPLY______Which one did you find better ? This one or the Cherno ? Which one will you suggest to a beginner in graphics programming ? (I know C++)
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
Yeah, it can be a bit fast at times, but it's hard to find a good balance. Too slow and more advanced programmers will get bored and just quit, too fast, and beginner programmers will get lost and quit. I tried to do it somewhat in between fast and slow, with fast programming, but slow explanations. Thanks for the compliments though :) And good luck with your project!
this tutorial is easy to understand and it explains the details of how to properly make the graphics work maybe if i have a time thank you for this tutorial.
Learning OpenGL makes me feel like I am learning black magic. It feels surreal to use the core and the quite dreaded concepts of C++ so much. I didn't even know that there is something called a "void pointer", which is basically a shape-shifter beast that cannot be killed unless it takes on a proper form.
Quick info. Open GL is not a framework or library, it's just a set of rules/guidelines that each Graphics card companies have to implement. And we as programmers have to call them. Hence each card has different openGL API
*Creating 3D Graphics with OpenGL and C++: A Comprehensive Tutorial* * *0:00** Introduction:* The course provides an overview of OpenGL, a cross-platform graphics API used for rendering 2D and 3D scenes, emphasizing the utilization of GPUs for parallel processing in graphics rendering. * *1:22** Installation and Setup:* The video guides viewers through installing necessary tools and libraries like CMake, GLFW, and GLAD, and configuring Visual Studio for OpenGL development. * *6:34** Window Creation:* The tutorial demonstrates how to create an OpenGL window using GLFW, including handling window events and adding color. * *14:25** Rendering a Triangle:* The video covers the basics of the graphics pipeline, explaining vertex and fragment shaders, vertex buffer objects (VBOs), and vertex array objects (VAOs), ultimately rendering a triangle. * *29:24** Index Buffers:* This section introduces index buffers to optimize rendering by reusing vertices and avoid duplicates, showcasing this with multiple triangles. [From Comments] There's a timestamp list for those who need it. * *32:33** Code Organization:* The tutorial emphasizes code organization by introducing classes for shaders, VBOs, EBOs, and VAOs, enhancing code readability and reusability. [From Comments] Many commenters appreciated this focus on organization after the initial basics. * *38:34** Shaders In-Depth:* The video delves deeper into shaders, explaining their properties, adding vertex colors, and introducing uniforms for controlling shader variables. * *46:38** Textures:* This section focuses on loading and applying 2D textures using the stb library. [From Comments] The instructor added numerous links in the comments to relevant documentation for OpenGL, GLTF, and other libraries, supplementing the information provided in the video. * *56:07** Going 3D with Matrices:* The tutorial explains 3D transformations using matrices (model, view, and projection) provided by the GLM library. It demonstrates creating a 3D pyramid and adding basic rotation. * *1:04:09** Camera Control:* This section implements a camera class for controlling viewpoint and movement within the 3D scene using keyboard and mouse inputs. [From Comments] Several viewers appreciated the camera control implementation and shared tips on extending its functionality, such as adding window resizing capabilities. * *1:10:10** Lighting Basics:* The tutorial introduces basic lighting concepts, including diffuse, ambient, and specular lighting, utilizing normals to calculate light interaction with surfaces. * *1:18:15** Specular Maps:* This part covers using specular maps to enhance lighting realism by controlling specular reflections based on texture data. * *1:20:17** Light Types:* The video explores different types of light sources: point lights with attenuation, directional lights, and spotlights, demonstrating their implementation and effects. * *1:24:33** Mesh Class:* This section combines previous concepts into a mesh class, wrapping vertices, indices, and textures for rendering complex objects. [From Comments] There's a comment detailing how to compile this code on Linux using g++. * *1:31:27** Model Loading:* The final section builds a basic model loader to import 3D models in GLTF format, utilizing JSON parsing for accessing model data. [From Comments] The instructor acknowledges the limitations of this basic importer, recommending Sketchfab as a good source for models that tend to work well with the importer. I used gemini-1.5-pro-exp-0801 on rocketrecap.com to summarize the transcript. Cost (if I didn't use the free tier): $0.19 Input tokens: 53141 Output tokens: 742
In case anyone else finds his triangle vertices calculations confusing, I might have a better explanation: The height of an equilateral triangle is sqrt(3) / 2 when the side length is 1. The distance of the top vertex to the centroid is 2 times the distance from the centroid to the midpoint on the base, so the ratio is 2:1. The y_offset is a third of the triangle's height: (sqrt(3)/2) / 3 = (sqrt(3)/2) * 1/3 = sqrt(3) / 6. This is Python code btw, you'll have to translate it to C yourself. I would recommend using the sqrtf function instead of float(sqrt(x)) like he does, since sqrtf returns a float directly. y_offset = sqrt(3) / 6 x1, y1 = -0.5, -y_offset x2, y2 = 0.5, -y_offset x3, y3 = 0, y_offset * 2 In my mind that is clearer. Multiplying y3 by 0.5 didn't make any sense to me, although it is equivalent.
This course is so fun and it is really interesting to see how OpenGL works. I currentlly used mingw and vscode. I got the libglfw3.a and the libglfw3.dll from the windows binaries and to compile the code i used g++ to link the libraries and include the include folder. But thanks anyways for showing me how to set up a OpenGL project in VS.
Heads up for anyone concerned - this works perfectly fine with Visual Studio 17 (Visual Studio 2022). The application's Intellisense will take a hot second (usually one-two days at worst) to comprehend all the functions inside the glfw/glad libraries but will work and help later on.
1:20:08 i've checked and double and triple checked i copied the code EXACTLY as he shows on the screen (I watched at 0.2x speed) but my specular lighting doesn't look like that, there's a small sphere of light on the floor, the rest is 100% dark, any suggestions? EDIT: checking the code on github it's a bit different, I guess he changed it after making the video, so it seems you can't follow along just by watching the video. shame!
The whole process of cutting/copying/pasting stuff between different explorer windows around 4:00 would be made so so so much easier and faster with Total Commander
Instead of making a header and a cpp file for classes, you can immediately go and create a c++ class that does that automatically, only is left for you to do is create your function interface. Also, to avoid re-typing the function to define in in the cpp file, you can right-click on the green underlined function declaration in the header, go to quick action and refactorization, and create function definition. I bound a key shortcut for that, you might wanna do that too. also for constructor initialization you may also do this: class MyClass { int a_in_class; MyClass(int a_in_constructor) : a_in_class(a_in_constructor) { /*do something */ } };
There is one issue though: when you create class, it is always created in solution root directory which might be annoying if you want to create it in subfolder, like src/Object/Object.h. This can be done by redacting full path but this is more annoying than creating two separate files. Plus practicing these actions never hurts because you might have a different IDE some day.
I had trouble getting the colour to show at the start. I removed the following lines and it worked fine: 8:36 glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3); glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3); glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
17:30 - Last line of the fragment source shader has a new line character at the end. This caused the fragment shader not to work for me (when the fragment shader does not work, the shader will colour everything in white).

Quick info. Open GL is not a framework or library, it's just a set of rules/guidelines that each Graphics card companies have to implement. And we as programmers have to call them. Hence each card has different openGL API
Yes, but GLFW is a library.
Opengl does have a framework and a library , video card companies also have their own library to communicate with opengl and vice versa
This is the best OpenGL course I saw.
why is this so mind numbingly complicated. Great tutorial explaining it all.
Because OpenGL is reasonably flexible with what it allows you to do (Aka low level).

y_offset = sqrt(3) / 6
x1, y1 = -0.5, -y_offset
x2, y2 = 0.5, -y_offset
x3, y3 = 0, y_offset * 2
In my mind that is clearer. Multiplying y3 by 0.5 didn't make any sense to me, although it is equivalent.

Really helpful for understanding 3d rendering process,❤❤❤❤❤❤❤❤❤❤❤❤
Looks really good for covering fundamentals and Game Engine design.
Such a good course made SO FRUSTRATING by the fact that it's sped up so much that you have to scrub through frame by frame in order to catch changes.
1:20:08 i've checked and double and triple checked i copied the code EXACTLY as he shows on the screen (I watched at 0.2x speed) but my specular lighting doesn't look like that, there's a small sphere of light on the floor, the rest is 100% dark, any suggestions? EDIT: checking the code on github it's a bit different, I guess he changed it after making the video, so it seems you can't follow along just by watching the video. shame!
that set up was pretty lit
This channel... it fucking rocks.
17:30 Bad... I want link of this code
U guys are literally reading our minds
Yo I was about to prepare for a computer graphics class, this is the vid all thanks!
Very good. Thanks. My only criticism is the volume is very low - relative to most other media/content. Other than that thank you very much.
Needed this badly! Thank you
Great tutorial! Excellent explanations
Thank you very much for this lesson,!!
Perfect tutorial , thank you
The whole process of cutting/copying/pasting stuff between different explorer windows around 4:00 would be made so so so much easier and faster with Total Commander
Also just to add, this tutorial is amazing. Thank you!
@@Morax Thanks, glad you liked it! :)
This is one grateful comment section!
You even went through all the trouble to make the additional excercises so we could train! I feel bad for enjoying this gold for free
Good to know some people actually do them haha
I think most people missed those :c
very nice my friend, very nice indeed, never stop though
This course is very useful and easy to follow even in normal speed of the video. Thank you very very much for making this
after 03:09 i get an error in cmake "Error in configuring process, project files may be invalid". What do i do then?
Do cmake and glfw need to be the exact version you are using?
Ok nvm, it was cause i apparently forgot to install c++. I m stupid
53:11 if you get the error you can change the GL_RGBA to GL_RGB, anymore questions about this problem reply to me.
Thanks Man Was stuck 😁
@@mr.bun-bunny8830 no problem
in Visual Studio 2022, where do i find project properties? ( 4:55 ) .
I dont think i have seen a single youtube video which has zero disllike ...
this one has 380K+ views 11K likes no dislikes .. nicee
Wow I just recently got interested in CG programming , this is perfect!
Instead of making a header and a cpp file for classes, you can immediately go and create a c++ class that does that automatically, only is left for you to do is create your function interface. Also, to avoid re-typing the function to define in in the cpp file, you can right-click on the green underlined function declaration in the header, go to quick action and refactorization, and create function definition. I bound a key shortcut for that, you might wanna do that too.
also for constructor initialization you may also do this:
class MyClass {
int a_in_class;
MyClass(int a_in_constructor)
: a_in_class(a_in_constructor)
{ /*do something */ }
};
There is one issue though: when you create class, it is always created in solution root directory which might be annoying if you want to create it in subfolder, like src/Object/Object.h. This can be done by redacting full path but this is more annoying than creating two separate files. Plus practicing these actions never hurts because you might have a different IDE some day.
Yeah, I recently saw this in a tutorial. But tbh I still prefer the manual way. Thx for the tip though! ;)
@@VerMishelb well, you can just move the newly created class files in the dir you want them in.
I had trouble getting the colour to show at the start. I removed the following lines and it worked fine:
8:36
glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
17:30 - Last line of the fragment source shader has a new line character at the end. This caused the fragment shader not to work for me (when the fragment shader does not work, the shader will colour everything in white).
For me too
I just quickly wanna say I actually showed this to my real friends... 13:45
people who have friends don’t flex them lmfao
@@rewrittenbytes1616 Just a meme bud
What books you recommend me to learning and improve all this ?, sorry for my english jeje.
Soooo, do I have to do all the steps before 6:40 everytime? Or can I just commit the files to a repository and use it as a template?
Wow!!! This is pure gold!!
honestly a great video
Thank you ^-^
@@VictorGordan (:
Thanks man this is really helping me😀
Please make Vulkan crash course also. Very much needed.
I really needed this. Thx!
