Game Engine Programming 032.1 - DirectX (DXGI) Swap Chain | C++ Game Engine
Right now we're in the middle of implementing a DirectX 12 renderer and so far we've created a d3d12 device, a command structure to submit work to GPU, and we spent the last episode writing a descriptor heap allocator which helps us to easily place descriptors in descriptor heaps. Now we've got enough tools and infrastructure to prepare and set up the render surface which is used to present the final rendered image on the screen. DirectX provides this functionality through an interface called a swap chain which can be roughly described as an array of render target textures that will be swapped with each frame. So, today we're going to write a class that creates and manages the swap chain.
