In episode 35, I talked about creating pipeline state objects (PSOs) and we saw that we can use a PSO to load shader programs for different programmable pipeline stages. The shader programs in D3D12 are written in HLSL which stands for High-Level Shader Language, and compiled into intermediate binary byte code that can be processed further by the driver when we create a pipeline state object. The driver will then turn this byte code into a format that can be uploaded to the specific GPU in the system. This episode in the game engine series is about compiling shaders and reading them in the engine so that later, we can get their byte code and use it during PSO creation. Today's video is about setting up the sub-module for managing compiled shaders in the low-level renderer and the next videos will deal with the actual compilation of shaders using DirectX Shader Compiler.
