❗ This project is a work in progress (pre-alpha). Frequent API changes, ABI changes, crashes... ❗

Vulkan 2D Renderer is a C++17 library designed to be easy to use, high performance 2D rendering backend for realtime applications. You only need a few lines of code to create a window and display simple shapes. On the other hand you can create a variety of different effects using meshes and applying different modifiers to them. Internally workloads are automatically grouped to create more efficient submissions to the GPU and all resource loading and saving is multithreaded.

• This project is primarily a passion project.
• Vulkan 2D rendering engines/libraries are not common.
• I didn't find any easy to use 2D rendering libraries with multi-window support.
• This should work pretty well as an example for people wanting to see concrete Vulkan API use. (Feel free to message me if you have any questions about anything)

• Easily generate and draw simple shapes. ( Box, Circle, Pie... )
• For more control you can also draw custom shapes direcly from vertex and index lists.
• Transformations and transformation hierarchy.
• Instanced rendering.
• Multi-window support.
• Mesh modifiers to warp and distort shapes.
• Textures, Samplers, Color and alpha blending.
• Render target textures with blurring.
• Multisampling.
• Multi-threaded resource loading and saving.
• Keyboard, mouse and gamepad input.

• Does not render 3D, this is meant to be a simple library to use.
• This is not a game engine, the purpose of this library is strictly limited to 2D drawing.
• No HDRI image support. Didn't find any use for this in a 2D application.
• No scene management, although transformation hierarchy is implemented so you can create your own.
• No custom shaders, might implement these later if there's any need for these.
• Work in progress. We'll know more about limitations later.
• Crashes and garbage renders will likely happen frequently.

❗ You will need to use Git, direct download from GitHub will not work because of dependencies. ❗

Prior to building this library on any platform you will need:

• Git 2.20 or newer
• CMake 3.16 or newer
• Vulkan SDK 1.2 or newer

If using the build tool you will need (recommended for new users):

• Python 3.8 or newer

If you're building the documentation you will also need these (disabled by default):

• Doxygen 1.8.20 or newer

Getting the sources is the same process on all platforms. On your command line or terminal, navigate to the folder where you wish to download the sources and copy-paste this line.

git clone https://github.com/Noxagonal/Vulkan2DRenderer

There are couple of ways to compile this library, you can use standard CMake or you can use the provided build tool.

Navigate to the Vulkan2DRenderer folder and simply run Build.bat on Windows or Build.py on Linux. To get started quickly, you can select the quick build option, this will generate the project files in build_tool/Release and build_tool/Debug folders and compiles the project, on windows this library is also installed into a folder. Please note that the included build tool generates a build_tool folder and is reserved for the built tool itself.

On Windows installing will create an build_tool/install folder which will contain everything you need to use this library on your project. You will have to manually link it to your project and move the VK2D.dll and VK2D_d.dll files somewhere where your executable can see it, usually to your project's working directory. The VK2D.dll is the release version and the VK2D_d.dll is the debug version of this library.

On Linux installing requires superuser priviledges so you need to do this separately, the build tool will build the project files and compile but it will not install this library for you.
