Reddit mentions of Practical Rendering and Computation with Direct3D 11

On the math side I read 3d Math primer for graphics and games as it was one of the only 3d math books available for the kindle. It is a pretty easy read and covers a lot of subjects. I'm considering picking up Essential Mathematics for Games and Interactive programming as a refresher if it ever gets released as an ebook since I've seen it be recommended a few times and it is a slightly more recent text.

As for the 3d programming side, it really depends on what you want to do. I chose to program in opengl and picked up the opengl superbible, which I would recommend. I've not touched directx yet, but have heard good things about Practical Rendering and Computation in Directx11 though I don't think this is intended as an introductory text for directx, but as a reference for those familiar with 3d already.

That guys youtube channel has DirectX 11 C++ tutorials. He has a beginner series, intermediate, and advanced. He still adds to the advanced occasionally, like SSE explanations and so on.

His videos are long, you really get to know him and his personality. His beginner videos teach you C++ too, he doesn't expect you to know anything going in. He swears fairly often, I thought it was funny back in high school when I watched these, but others might not.

These videos are where I started from in the very beginning, and I wouldn't be where I am programming wise if it weren't for Chilli. He has allowed me to educate myself on my own time, for free. After I had done the beginner and intermediate tutorials I went and read this.

That will teach you the basics of 3D Programming.

And that will teach you how to really understand the pipeline. Both books have their merits and both have very useful information for someone learning all this stuff. I'm currently making my own 3d game engine at the moment, so that's what understanding the information above can do for you. Takes time, though.

I recommend Practical Rendering and Computation with Direct3D 11, it is not specific to game programming, but provides a good detail on how API maps to hardware and its use. This helps even if eventually end up using Unity or Unreal or other engines. Once you understand the low level architecture, it is very easy to find the corresponding API parts in OGL to accomplish similar stuff.

Practical D3D Rendering and Computation
Distills the API quite well and explains a lot of pitfalls with creating buffers and the pipeline usage. I'm working on just reading it so I'm familiar with D3D 11+ even though I don't use it day to day.

Real-time Rendering 3rd edition

Another fantastic reference for graphics with a more theoretical look at things, explains TONS of modern techniques and even older ones such as rasterization on CPU, etc.

If you're really serious about getting into 3D-programming with DirectX I recommend getting a good book. A quick search on Amazon will get you the most common ones.
As for online resources my favorite is braynzarsoft.

EDIT:
My favorite books on DirectX:
