I'm waiting for your new book on AGK.
When will the book be released?
Can you recommend any literature on 3D programming?
Something that 3D programming understands from scratch.
First theory, then commands and application in practice.
Something popular...

What new book? I think it's very unlikely a new book will be released. Have you taken a look at the books that are currently available?

I've started studying 3D graphics programming recently and I signed up to https://pikuma.com/courses/learn-3d-computer-graphics-programming

The course is quite good so far, using C and SDL.

New book...

By AppGameKit Studio - two books are sold.
I wanted to read something else on 3D graphics programming.
It is possible in any language.
In principle, under DirectX - they should be similar technologies...

That link is out of date unfortunately. The Game Creators no longer sell the books, you have to buy them direct from Digital Skills using the link I provided above.
