DirectX-Graphics-Samples VS Xbox-GDK-Samples

I also looked at the Microsoft sample like this: https://github.com/microsoft/DirectX-Graphics-Samples

It looks like Microsoft has official DirectX samples available, including an SSAO demo if you want to take a look at that. It does seem very different compared to your approach though, so it may not be of any use to you.

In my post I was using the generate mipmaps example to illustrate what I'm saying. In order to generate mipmaps in realtime in OpenGL you would simply make a call to generatemipmaps() or whatever it is called. In Vulkan it is more challenging because you have to do explicit resource management, but it isn't that bad still. In D3D12 you have to write your own compute shader https://github.com/Microsoft/DirectX-Graphics-Samples/blob/master/MiniEngine/Core/Shaders/GenerateMipsCS.hlsli

I wrote a sample a few years ago which implements this technique.

I eventually moved on to the official DirectX 12 Graphic Samples, which had isolated examples that were easier to learn from incrementally. The “Hello World” sample is the best starting point to get the renderer setup with a triangle. This repo is a great reference when you need to verify process and structure (like the order of operation of APIs). Whenever I had a strange bug in my app, I’d go back to these examples to do a diff and see what I was missing.

You probably want to take a look at the officiel DirectX samples page: https://github.com/microsoft/DirectX-Graphics-Samples It’s got samples covering a single topic each, which make them easier to digest, but there’s also the MiniEngine which is a render engine.

Something about the Github sample did catch my eye:

Microsoft put out this: https://github.com/microsoft/DirectX-Graphics-Samples

There is also this thing, but I never figured out how to compile that.

The DXTK also has a great tutorial series on creating a game loop that breaks down the DX12 pipeline through the process. They also have a repo with Xbox game SDK samples (not games — but features you’d use in games like gamepad input).
