The current version of GLFW, writing this article, is the third: GLFW3. What does it means it that GLFW is a helper library that starts the OpenGL “context” (a running copy of OpenGL, tied to a window) for us, and talks to a lot of platforms / operating systems in the same way. OpenGL ES (outch…), and Vulkan on desktop. GLFW is an Open Source API for creating windows, contexts and surfaces, receiving input and events, for OpenGL, Range of operating systems (despite the fact that Apple deprecated the version >= 4.2 a few years ago to introduce However, Vulkan is still young and is way more complicated to learn than learning OpenGL.įor this project I wanted to do simple graphics computing before, and it seems OpenGL is still supported in a large I am not opposed to Vulkan at all: performances are great, great ideas behind, and multiplatforms.

Why not Metal with C++ ?Įven if Apple Metal is great (actually, the API is pretty awesome), it is unfortunately specific to Apple products, and I wanted to work on something with platforms that do not include only Apple.Īlso, Metal is still a pretty young API and the documentation is not quite right sometimes… And why not Vulkan? The goal of this (first?) part is to draw the famous RGB triangle, on the m1 mac, using C++17. I am using modern C++ (C++17) for this project, mainly because I really like modern C++. Shaders in GMS2 use ( (GLSL), the OpenGL Shading Language,

I choosed OpenGL because I am prototyping with GameMaker Studio 2, and writing shaders for it. Here, I wanted to go further in exploring OpenGL and / or Vulkan, for multi-platform GL.

I began to work on a very simple Game engine in Swift / Metal last year but I began to switch to a Windows machineĪ few months ago, and Swift / Metal is not compatible with Windows (and will never be I think). Since a long time now I was interested in learning computer graphics and “do stuff” with computer graphics APIs.
