Lecture 12: DX12 initialization

Validation layer

To engage API validation:

1. Call D3D12GetDebugInterface function to get debug controller
2. Call EnableDebugLayer method of the debug controller
3. Use DXGI_CREATE_FACTORY_DEBUG flag in further DXGI factory creation [1]

Hardware adapter

• Use CreateDXGIFactory* function to create a DXGI factory (don’t forget about flags)
• Call EnumAdapters* method to find HW
• EnumAdapters for adapter #0 gives us a pointer to the primary display adapter [1]

Device and command queue

• Call D3D12CreateDevice function to create a DX12 device
• Make sure that minimum future level is D3D_FEATURE_LEVEL_11_0
• Call CreateCommandQueue method of DX12 device to create a direct queue [1]

Swap chain

• Call CreateSwapChainForHwnd method of the DXGI factory with Direct queue, window handler and swap chain descriptor
• Call MakeWindowAssociation method of the DXGI factory with window handler and DXGI_MWA_NO_ALT_ENTER
• Cast the swap chain pointer to required COM interface [1]
