Librush Examples

Example apps and a test harness for librush, covering basic rendering API usage.

How to build

The easiest method is to use CMake presets:

cmake --list-presets
cmake --preset <preset>
cmake --build --preset <preset> [--target Tests]

Build output goes to Build/<preset>/....

Common presets:

• Windows vs2022-vk, vs2026-vk
• Linux ninja-debug-vk, ninja-release-vk
• macOS ninja-debug-vk, ninja-release-vk, ninja-debug-metal, ninja-release-metal, xcode-vk, xcode-metal

How to run

./Build/<preset>/01-HelloWorld/01-HelloWorld
./Build/<preset>/Tests/Tests

External dependencies

• Vulkan builds require the Vulkan SDK (VULKAN_SDK or VK_SDK_PATH set). MoltenVK on macOS.
• Metal builds on macOS require the Metal toolchain (install with xcodebuild -downloadComponent MetalToolchain).
• Shader tools: glslc is used for shader compilation; spirv-cross is used on macOS for Metal shader translation.
