Errata: turns out that OpenAL is actually not governed by Khronos. This Open* prefix can be confusing...

My first contact with OpenGL was with the MiniGL driver, a "propriatary incomplete implementation"(yeah, that's a term) of openGL by 3Dfx which allowed OpenGL games ( mostly quake ) to run on 3Dfx Vodoo cards. John Carmack didn't care to implement 3fdx Glide for Quake, so 3dfx implemented what Carmack used and then other devs tried to use OpenGL in a way that it works with MiniGL which, as mentioned, was closed source and incomplete and since ID never released a list of OpenGL functions they used and 3Dfx never released a list of OpenGL functions they reimplemented, there was some guessing involved during a time when OpenGL was not fully supported by GPU drivers, Direct3D was considered crappy.

@valtovar 17 дней назад

Nice video! I'd like to see some of the OpenGL and/or Vulkan videos running on SDL2/3, at least the initial setup. I have observed that many engines prefer this library.

@OGLDEV 16 дней назад

I can take a look at SDL in the future but for now I have to focus on the core of OpenGL and Vulkan. I have seen many tutorials on SDL that actually show you how to create a complete game with it so I guess it's a much more extensive library than GLFW.

@jtsiomb 17 дней назад

Nice overview. But OpenGL is definitely still available on the mac. Apple calls it deprecated to try and scare people into using metal, but baring terminal insanity (which is always possible for apple), OpenGL support will probably never go away.

@vvgr409 17 дней назад

I wouldn't be so sure about it. Apple is not afraid of removing old things and breaking backwards compatibility. They made it pretty clear when they removed 32 bit application support. Nothing stops them from removing OpenGL as well since most modern macOS apps are using Metal anyway.

@jtsiomb 17 дней назад

@@vvgr409 You might be right, we'll see. The fact remains however that OpenGL is currently still supported on macos.

@OGLDEV 16 дней назад

Thanks! I've seen messages by Unity that they are also going to remove OpenGL support on Mac following Apple's deprecation statement so I would be very hesitant to continue developing in OpenGL there.

@OGLDEV 17 дней назад

Ofcourse ;-)

@voytechj 16 дней назад

With new OpenGL core context some old GL functions were deprecated and removed, but including glew header those function names still exists and you can use them by mistake. GLAD will generate headers without those pesky function :).

@OGLDEV 16 дней назад

True, and using core profile in GLFW also helps avoiding deprecated stuff.

@syntaxed2 17 дней назад

What are your thoughts on WebGPU and its abstractions over vulkan/dx/metal? - A decent replacement for opengl?

@OGLDEV 16 дней назад

I have to admit that I'm not familiar with WebGPU. Not sure if I would put it head to head with OpenGL since it's intended for the browser. I guess the best comparison is WebGL. Will be interesting to see where it goes.

@syntaxed2 16 дней назад

@@OGLDEV WebGPU has become a native solution now tho :D

@OGLDEV 15 дней назад

What do you mean by 'native'?

@hakeemadam955 14 дней назад

@@OGLDEV I would highly suggest you look into WEBGPU. Native means it runs on desktop with bare C++ or rust. Bevy, the rust game engine uses WebGPU. The only downside is that it is new and lack documentation, but WebGPU is probably the only truly cross platform API, afaik. Thanks for all your work!.

@Vicente_Lopes_Senger 17 дней назад

I have used GLFW and GLAD, now I'm loading the function pointers myself and opening the window with the Win32 API for no pragmatic reason, and contrary to common sense, since I plan, at least for now, to also release the game on Linux.

@OGLDEV 16 дней назад

@Test-iv4pm 15 дней назад

When you make a game, what objects do you start making first?

@OGLDEV 14 дней назад

I have to admit that I'm not experienced with actual game development but my guess is that the answer depends on the type of game that you are developing. Is it outdoor or indoor? Do you need an animation system? Do you need to render terrain? Is it a 3D platformer? You should probably start with the largest objects and drill down to the smaller details. Just my 2cents...

@monamodikgwete3423 10 дней назад

Hello. Do you assist if someone is stuck and needs your help? I am learning OpenGL and I tried to follow your tutorial on Object picking but I fail to follow, I need help with picking and would really appreciate your help.

Sorry, but I work full time so I don't have time for such help. If you send me specific questions I'll try my best to answer.

@ar_xiv 15 дней назад

OpenGL still works on all apple computers btw. It's "deprecated" but likely not going anywhere.

@OGLDEV 15 дней назад

True, but I doubt that anyone will start a new project using OpenGL on the Mac. Maintenance of existing code at the most.

@ar_xiv 15 дней назад

@@OGLDEV Raylib and Monogame both still use OpenGL on mac, but that might change at some point

@OGLDEV 15 дней назад

I suspect they won't be writing a lot of new OpenGL code on the mac.

OpenGL and Modern OpenGL.... We need a SUPER Modern OpenGL. 3.3 and 4.5 (DSA) are pretty different.

@OGLDEV 14 дней назад

DSA is considered modern OpenGL, but right now it doesn't look like they are going to create a super modern OpenGL...
