Vulkan examples

The examples form a practical learning path from a single triangle to complete interactive scenes.

Recommended order

1. GLFWWindowDemo — create a Vulkan-compatible window.

2. DrawTriangleDemo — context, swapchain, dynamic rendering, and indexed draw.

3. DrawTextureDemo — image upload, sampler, and texture descriptors.

4. DepthTestingDemo — depth resources and depth pipeline state.

5. LoadModelDemo — model loading and indexed geometry.

6. MipmapDemo — mipmap generation and sampled textures.

7. MultiSamplingDemo — multisampled rendering and resolve.

8. CubeMapDemo — cubemap images and skybox rendering.

Compute and simulation examples

• ComputeBarycentricRasterizer implements rasterization through a compute shader.

• GalaxyDemo and PhysicsDemo demonstrate animated workloads.

• CarControlDemo and FPSShooterDemo combine several renderers into interactive applications.

Build

./scripts/sync_data.sh
./scripts/run.sh -t macos

Run the selected executable from the CORE repository root so relative shader and asset paths resolve correctly.

# Start with the smallest graphics example.
./build/macos/examples/vk_triangle_demo

# Then exercise textures and model resources.
./build/macos/examples/vk_texture_demo
./build/macos/examples/vk_model_demo

Read an example efficiently

For each example, begin with main.cpp to see object ownership and the frame loop. Then inspect its Render*.h for the VulkanRender specialization and its Render*.cpp for resource upload, descriptor writes, and draw recording.

For example, DrawTriangleDemo separates responsibilities like this:

main.cpp
  window + surface → context → swapchain → frame loop

RenderTriangle.cpp
  staging buffers → descriptor set → graphics pipeline → draw commands

Note

Run examples from the repository root. Several examples depend on relative asset paths, and scripts/sync_data.sh populates assets maintained in the separate core_data repository.
