4.4.3 Subresources

You are likely familiar with textures and the mipmaps associated with

them. Classical mipmapping is about generating a pyramid of textures, the

original texture having the highest resolution and living at the base of the

pyramid, and the tip of the pyramid having the lowest resolution. It is pos-

sible to create a texture in D3D11 and declare that it should have mipmaps.

The texture and mipmaps are said to be subresour ...
