Ready-made libraries mean Direct 3D, OpenGL and Vulkan?
Then you need to write a rasterizer with athenian or better perspective texturing, in principle, nothing complicated, at one time I wrote a replacement for OpenGL 1.2 so that you could play elementary games))
If you mean the principle of construction, then you first need to install a 3D editor, for example Blender to see what and how models are made of, after you understand what everything that you see in games consists of, you can draw an elementary level)) use 2.5D or 3D to store maps. Naturally, all geometry will have to be remembered ... at least elementary ala products of matrices, matrices and vectors, etc.
Here are examples on Delphi 7/10 that I once made for my sites back in 2005-2007:svsdval.hldns.ru/delphigfx.mirgames.ru_and_svsd.mi...
