1. OpenGL Software Development Kit :great tutorials & Libraries

OpenGL SDK Welcome to the OpenGL SDK! Here you'll find some of the most valuable resources available to OpenGL developers, all in one place. Use the menu above to navigate to each contribution. Revisit often, as there will be new contributions coming online all the time!

The OpenGL SDK is a gathering of 3rd party contributions from many of the leaders in the community. In some cases the information and downloads are available directly from the SDK on opengl.org. In other cases, you'll find links to the original materials elsewhere on the web. In all cases, the contributions have been hand selected and represent the best of what's out there.

3. GLEW vs GLAD?

I've been seeing a lot of people using GLAD lately and dropping GLEW. Are there any advantages in that library?

glad all day every day. There's a web service so you don't have to mess around with generating a loader yourself. I've used it in one of my projects and it seriously is the best in my opinion.

GLAD is a library that you customise for your explicit task, which should be setting off all manner of alarm bells in your head.

1. GLEW is a library that you can drop into your project and that is the end of it.
2. This should be the end of the discussion.
4. OpenGL: best openGL link

Before starting our journey we should first define what OpenGL actually is. OpenGL is mainly considered an API (an Application Programming Interface) that provides us with a large set of functions that we can use to manipulate graphics and images. However, OpenGL by itself is not an API, but merely a specification, developed and maintained by the Khronos Group.

Image of OpenGL's logo The OpenGL specification specifies exactly what the result/output of each function should be and how it should perform. It is then up to the developers implementing this specification to come up with a solution of how this function should operate. Since the OpenGL specification does not give us implementation details, the actual developed versions of OpenGL are allowed to have different implementations, as long as their results comply with the specification (and are thus the same to the user).

5. Creating a window

The first thing we need to do before we start creating stunning graphics is to create an OpenGL context and an application window to draw in. However, those operations are specific per operating system and OpenGL purposefully tries to abstract itself from these operations. This means we have to create a window, define a context, and handle user input all by ourselves.

Luckily, there are quite a few libraries out there that provide the functionality we seek, some specifically aimed at OpenGL. Those libraries save us all the operation-system specific work and give us a window and an OpenGL context to render in. Some of the more popular libraries are GLUT, SDL, SFML and GLFW. On LearnOpenGL we will be using GLFW. Feel free to use any of the other libraries, the setup for most is similar to GLFW's setup.

8. GLFW offical site

GLFW is an Open Source, multi-platform library for OpenGL, OpenGL ES and Vulkan development on the desktop. It provides a simple API for creating windows, contexts and surfaces, receiving input and events.

GLFW is written in C and supports Windows, macOS, X11 and Wayland.

9. The OpenGL Extension Wrangler Library

The OpenGL Extension Wrangler Library (GLEW) is a cross-platform open-source C/C++ extension loading library. GLEW provides efficient run-time mechanisms for determining which OpenGL extensions are supported on the target platform. OpenGL core and extension functionality is exposed in a single header file. GLEW has been tested on a variety of operating systems, including Windows, Linux, Mac OS X, FreeBSD, Irix, and Solaris.

it has links to sourceforge and github

10. OpenGL Loading Library

An OpenGL Loading Library is a library that loads pointers to OpenGL functions at runtime, core as well as extensions. This is required to access functions from OpenGL versions above 1.1 on most platforms. Extension loading libraries also abstracts away the difference between the loading mechanisms on different platforms.

Most extension loading libraries override the need to include gl.h at all. Instead, they provide their own header that must be used. Most extension loading libraries use code generation to construct the code that loads the function pointers and the included headers. Information is available if you wish to perform this manually, but you are encouraged to use one of these libraries yourself.

11. How to Set Up OpenGL‐GLFW‐GLAD on a Project with Visual Studio

Many programmers prefer OpenGL for graphics. If you are one of them, you are strongly advised by its producer to use a window toolkit (such as GLFW) and an OpenGL loading libraries (such as GLAD). This guide will help you get over the first challenge of using OpenGL with GLFW and GLAD: Installing and setting them up, and creating your first project with OpenGL-GLFW-GLAD Template in Visual Studio 2017 or 2019.

12. How to Set Up an OpenGL FreeGLUT GLEW Template Project in Visual Studio

Many programmers prefer OpenGL for graphics. If you are one of them, you are strongly advised by its producer, to use a window toolkit (such as freeGLUT) and an OpenGL loading libraries (such as GLEW). This guide will help you get over the first challenge of using OpenGL with freeGLUT and GLEW: Installing and setting them up, and creating your first project with OpenGL-freeGLUT-GLEW Template in Visual Studio 2019.

13. How to Set Up OpenGL GLFW GLEW GLM on a Project with Visual Studio

This guide will help you get over the first challenge of using OpenGL, GLFW, GLEW, and GLM: Installing and setting them up, and creating your first project with GLFW-GLEW-GLM Template in Visual Studio 2019.

It will assume your platform is Windows and your IDE is Visual Studio. During the Visual Studio installation, check the Desktop development with C++ workload box.
