vulkan-examples-rs

Collection of Vulkan examples that I make to learn stuff in Rust using ash.

Examples

You can run one of the following example.

• rt_triangle: Ray-traced triangle.
• rt_shadows: Ray-traced gltf model with simulated sunlight shadow. It has one BLAS with multiple geometries. Light and camera controls with imgui.
• rt_reflections: Ray-traced iterative (not recursive) reflections.
• triangle: Rasterized triangle.
• gpu_particles: Particles simulated on the gpu using a compute shader.
• mandelbrot: Render mandelbrot set on gpu with expensive setting. The goal is to be gpu bound with a simple setup for some tests.
• hdr_skybox: Display a skybox from a environment HDRi image targetting an HDR surface.
• wboit: Weighted, Blended Order-Independent Transparency.

# Powershell example (all scripts have a .sh version)

# Compile all glsl shaders to spir-v 1.4
.\scripts\compile_shaders.ps1

# Enable validation layers and set log level to debug
.\scripts\debug.ps1 <example>

# Compiles with --release and set log level to info
.\scripts\run.ps1 <example>

Controls

For examples with interactive camera you can move the camera with

• WASD to move
• Ctrl and space to go up or down
• Right-click and move the mouse around to look

You can alse press R to cycle through the performance information.

Requirements

• Rust 1.77

All examples use Vulkan 1.3 and the following features:

• dynamic_rendering
• synchronization2

Ray tracing examples use the following extensions and features:

• VK_KHR_ray_tracing_pipeline
  • ray_tracing_pipeline
• VK_KHR_acceleration_structure
  • acceleration_structure
• VK_KHR_deferred_host_operations
• Vulkan 1.2's features
  • runtime_descriptor_array
  • buffer_device_address

RT is only enabled on examples using it, so other examples can run on hardware that does not support it.
