RHI

Graphic library provides generic independent API for rendering. Provided backends:

• Vulkan (in progress)
• DirectX (in plan)
• Metal (in plan)

My goal - is use modern low-level graphic API, but create a really simple API saving all features like multithreading
For learning this API, you'd better to watch on examples. Below is a list of examples.

Each example is a little test application which is tests some functional of API like uniforms, rendering geometry, multithreading and so on.
Watch examples in order of this list,

• HelloWindow - start example which should only open window and clear it with changing color
• HelloTriangle - basic graphic application - opens the window, clear color and draws a colored triangle
• Uniforms - you'd learn how to setup uniform variables (except Sampler2D)
• ParallelPass - very important example because it shows how to build an application to provide multithreaded rendering.
• Textures - a basic example that shows how to work with Sampler2D uniform
• DownloadImages - shows how to download image from GPU.
• TexturesArray - shows how to use arrays of uniforms: f.e uniform sampler2D var[5]. For buffered uniforms is similar.
• LayeredTexture - shows how to implement texture array properly (like Sampler2DArray). Also shows how to generate mipmaps.
• MultiWindow - example shows how to render into two windows. It's optional example

How to integrate and build

This project uses CMake as build system, so you can just download this project into folder and include it in your CMakeLists via add_subdirectory You can link it to another project via target_link_libraries(${target_name} PRIVATE RHI) Also you can define some options:

• RHI_VULKAN_BACKEND - RHI will be compiled with Vulkan backend.
• RHI_DIRECTX_BACKEND - RHI will be compiled with DirectX backend.
• RHI_METAL_BACKEND -RHI will be compiled with Metal backend
• RHI_BUILD_EXAMPLES - example applications from Example folder will be compiled

Dependencies

The library provides independent API, so you don't have to link any other libraries. Backends have their own dependencies which are intergrated with FetchContent

How to use

There is only one header file you need to include in code for using - RHI.hpp. It contains all interface declaration you can use to write code.
