FirstDX12Renderer

A series of examples on how to use Direct3D 12 for real-time graphics applications (e.g. videogames).
The examples will start from an empty window, and increase in complexity up to handle most of the base concepts when using this graphics API.

CMake Structure

Part1, Part2, Part3 and Part4 are target executables. These targets have dependencies on defined target libraries (both internal and external).
GEPUtils (Game Engine Programming Utilities) is the library that contains most of the graphics functions.
You can read my CMake Configuration Article.

Third Party Dependencies

Part 1

Part1 executable project is the simplest, an empty window that will showcase:

Handling a winapi window with a D3D12 pipeline state object.
Window resizing (and handling relative swapchain).
Reacting to input events from mouse and keyboard.

Part 2

Part2 executable target will showcase:

Render a cube using vertex and index buffer.
Rotation and translation upon mouse interaction.
Root signature with a root constant.
Vertex and pixel shader assigning color from per-vertex data.

Part 3

Part3 executable target will have most of Part2 features, plus:

Full graphics abstraction layer the app is potentially extensible to other APIs such as Vulkan.
Dynamic buffer to handle data that is changing once per frame, such as a pulsing color.
Descriptor heap staging descriptors on CPU and upload them to GPU when needed.
Constant buffer view referenced by a root table in the root signature.

Part 4

Part4 executable target will have most of Part3 features, plus:

Texture Handling first loading a cubemap from a file and then uploading it to GPU.
Static Descriptor to sample the texture in shader.
Generate Mips use a compute shader to generate 4 mip levels for the cubemap.

Notes

Note: This repo was tested in VisualStudio 2019 using FolderView Mode and CMake (Ninja generator + msvc compiler).

Note: Part of D3D12 code was heavily inspired to the 3DGEP DirectX12 guides, by Jeremiah van Oosten, you can find them by clicking here. He also has a corresponding GitHub repo, that can be found here.

Note: Code you will find is solely my own and does not express the views or opinions of my employer.
