This repository contains a C++ prototype demonstrating interoperability between WebGPU (via wgpu_native) and OpenXR. The goal of this project is to provide a modern, cross-platform, and explicit graphics stack for Virtual Reality applications, replacing legacy OpenGL and OpenVR workflows.

Structure

• src/main/: The core thesis prototype. An interoperability layer bridging WebGPU rendering with the OpenXR swapchain.
• src/webgpu/: A standalone WebGPU application to test graphics and windowing without VR overhead.
• src/openxr/: A standalone OpenXR application to verify headset detection and runtime configuration without graphics overhead.
• src/external/: Vendored dependencies (included in the repo for easy building).

Dependencies

Most dependencies are vendored in the src/external/ directory, meaning that you do not need to install them system-wide. The vendored libraries include:

• wgpu_native (WebGPU implementation)
• OpenXR-SDK (VR Runtime Loader)
• GLFW (Windowing)
• GLM (Mathematics)

System Requirements to Build

• CMake (v3.20 or higher)
• C++20 compatible compiler (GCC, Clang, MSVC)
• An active OpenXR Runtime installed on your system (e.g. SteamVR, Meta Quest Link, Monado)
• Linux only: Wayland/x11 development headers

How to build

This project uses standard CMake out-of-source builds. Open your terminal in the root directory of the project and run:

# Create a build
cmake -B build -S .

# Compile executables
cmake --build build

Usage

After a successful build, the executables will be located in the src/build

# Test WebGPU (Monitor Only)
cd src/build/webgpu && ./demo_webgpu

# Test OpenXR
cd src/build/openxr && ./demo_openxr

# Test Main
cd src/build/main && ./demo_main
