Writing a Vulkan renderer from scratch [Part 0]

I share my experience using Vulkan for the first time. I didn't get much done in this devlog, but this is very much on purpose. I spent a lot of time familiarizing myself with how Vulkan works and the theory behind its operation.

What a great series. We need deep knowledge instead of 24 hours game engine series, please go on.

I've found most of those "24 Hour Games" or "Make x in y" examples are usually pretty rough. Non-extensible, often slapdash code and buggy, doing things the 'wrong' way, lacking polish and features. It compiles and it runs, therefore it's eh good enough. One guy did Breakout in 10 minutes in Unity and it didn't even have a scoring system, all you did was make blocks disappear by hard deleting them with the Destroy/Dispose and they were all the same colour. Nah.

A little tip for fixing performance in vulkan: make sure you don't have the "apidump" layer enabled (on windows, that's defined in the layer path environment variable). apidump can be useful, but it will trash your perfomance, and spam the console with every single vulkan call/command.

I'll remember that, thanks for the tip!

I love it how you spend hours on something, you've written shedloads of code and it still doesn't work properly. You then look up someone else's example/tutorial and they've done the same thing in like 4 lines of bug-free perfection in a really slick way you'd never thought of. Makes me feel so small and so stupid. Like I should give up and work in a warehouse.

Stuff like this just puts me more in awe of professionals. To think that AAA games have multiple renderers built in (you can switch between them) and look universally gorgeous while working like Swiss clockwork is just amazing. The sort of talent that works on that part of the codebase is simply inhuman.

Well considering I made a ray tracer which is essentially a CPU only renderer, then I can probably manage a software rasterizer. My friend T3V made a software rasterizer, you can check it out on his channel. Thanks for watching!

What purposes does implementing support for both OpenGL, DirectX and Vulkan serves ? I thought one would be enough to cover any hardware, is that wrong ? Great video anyway, congrats to you for managing to do such low level stuff.

@AngeTheGreat 2 жыл бұрын

On a practical level, you are correct that just supporting Vulkan or OpenGL is probably enough. However, there is a wide variety of hardware that one may want to target and you can't always assume that they will support Vulkan or OpenGL. For a serious game engine that intends to be cross-platform, having a solid abstraction layer is essential and in addition to this, writing an abstraction layer is a good learning experience and allows you to see similarities and patterns in the different APIs. Hopefully that answers your question, thanks for watching!

In short... DirectX usually has the best driver support, but is only available on Windows and X-Box, pretty much. If you want your game to run on Linux, Mac or in the browser, you'll need to use OpenGL. But OpenGL tends to have really poor driver support, and has a lot of annoying quirks - that's where Vulkan comes in. Vulkan is designed for absolutely minimal drivers in the first place - you have a much closer access to the hardware. That means opportunities for really deep and powerful tweaks and optimizations... but it also means that you're working with something that's _really_ annoying to use and it's a lot of effort to support a variety of graphics cards. Basically, Vulkan is designed for people like John Carmack, who are constantly let down by the limitations of graphics drivers :) Unless you already have an OpenGL background, DirectX is probably the most convenient and fun to use, but it does mean essentially Windows only. And giving the user a choice between OpenGL, DirectX and Vulkan can actually result in performance gains, since different computers will tend to perform differently using each of these, even with all else equal. I actually prefer Vulkan to OpenGL, but that might be my constant bad experiences with OpenGL over the decades :D

@@yoyo12345 I mean you have to make the app of course. I never used it for mobile debelopment. I only know Vulkan and that Vulkan Supports Mobile devices, but the mobile device has to Support Vulkan too of course. That being said, I think Unreal Engine works with Vulkan on mobile. If you want do develop on a lower level (meaning without an engine) there is a Vulkan API in the Android NDK. For apple devices you generally have to use MoltenVK as a compatibility layer because Apple only support their own graphics API, but since Apples API is the same across all devices MoltenVK should work on iOS as well.

@Dragoo glfw is a library responsible for creating the window of your app. Glut is a library for graphics, so you basically render stuff (triangles, quads) inside your window you made with glfw. Glut is a library that works with opengl but it is very much abstracted and nobody uses it nowadays. I would recommend to start with glad or glew (they are mostly the same). The difference is that those 2 are basically raw opengl without any abstraction. So everything is a bit harder but it will make more sense than using something that does everything for you and you don't know whats happening behind the scene. After you learn opengl really really well (mostly won't happen soon) you can start using more low level api like vulkan or directx12.

@gogadenis8938 3 жыл бұрын

@Dragoo Performance. For example vulkan gives you full control over the gpu drivers. One of the key points of using vulkan over opengl is that vulkan is thread friendly that means that you can make your renderer multi-threaded. Its the same as programming languages. For example why we use c++ instead of python.

Yah honestly I just started reading through books to learn c++ open GL & python and I’d say I probably retain 40% of each chapter at most. At first 3D design was so alien and hard for me now I know the hot keys how to bounce from Maya to c4d to blender u name it. Imma start taking some community college courses and continue to learn things like python at my art school but yah it’s a lot harder then anything I have ever learnt but 3D thought me if u put ur brain in anything you can learn it! U just gotta have the passion
