libvultra

libvultra is the core library of Vultra, which can be used for rapidly creating graphics or game prototypes without the VultraEditor.

(This project is under early development and WIP.)

Features

• Modern Vulkan using Vulkan-Hpp, Vulkan-Memory-Allocator-Hpp and more
• FrameGraph (RenderGraph) based rendering system
• OpenXR support (now focusing on VR only, not AR)
• Modern SDL using SDL3
• ImGui docking + multiview

Showcase

Example: GLTF Viewer

[Example: Sponza with Meshlet Debug View]

Build Instructions

Prerequisites:

• Git
• XMake
• Vulkan SDK
• Visual Studio with MSVC if Windows
• GCC or Clang if Linux/Unix
• XCode with GCC or Apple Clang if macOS

Step-by-Step:

• Install XMake by following this.

• Clone the project:

  git clone --recursive https://github.com/zzxzzk115/libvultra.git

• Build the project:

  cd libvultra
  git submodule update --init
  xmake -vD

• Run the programs:

  xmake run

  or run a specific program:

  xmake run example-window
  xmake run example-rhi-triangle
  xmake run example-imgui
  xmake run example-framegraph-triangle
  xmake run example-openxr-triangle
  xmake run example-openxr-sponza
  xmake run example-raytracing-triangle
  xmake run example-raytracing-cornell-box
  xmake run example-rayquery
  xmake run example-meshshading-triangle
  xmake run example-gltf-viewer
  xmake run example-sponza

  Tips: For OpenXR programs, you may need to set the XR_RUNTIME_JSON environment variable. For debugging OpenXR programs without headsets, you may need Meta XR Simulator on Windows and macOS. On Linux, you can use Monado as the simulator.

TODO List

• Wayland support
• More powerful texture loader that supports KTX, KTX2, DDS and more
  • KTX
  • KTX2
  • DDS
  • EXR
• ECS-based scene management with EnTT
• Raytracing Pipeline
• Mesh Shading Pipeline
• Resource Pipeline
• Lua or C# Scripting System
• (Maybe?) AR support
