|
// Direct3D11.X runtime resource for it via the CreatePlacement APIs

// Note these functions will not load standard DDS files. Use the DDSTextureLoader
|
||
|
|
// module in the DirectXTex package or as part of the DirectXTK library to load
|
||
|
|
// these files which use standard Direct3D resource creation APIs.
