A real-time GPU ray tracer implementing Peter Shirley's 'Ray Tracing in One Weekend' using Vulkan's hardware ray tracing extension (VK_KHR_ray_tracing_pipeline). It renders procedural spheres and OBJ geometry at interactive frame rates with a Dear ImGui UI for tweaking renderer parameters.

Use cases

• learn hardware-accelerated ray tracing with Vulkan RTX
• render Ray Tracing in One Weekend scenes in real time on an RTX GPU
• see a reference implementation of VK_KHR_ray_tracing_pipeline in C++
• experiment with path tracing parameters like bounces and samples interactively
• load OBJ meshes like the Stanford Lucy into a real-time ray tracer

When to choose

• you have an NVIDIA RTX (or other hardware ray tracing capable) GPU and want interactive path tracing
• you want a compact, readable C++/Vulkan codebase to study real-time ray tracing
• you're following Shirley's books and want a GPU-accelerated companion implementation

When to avoid

• you need a production renderer with denoising, instancing optimizations, or offline quality output
• your GPU lacks hardware ray tracing support
• you want a general-purpose 3D engine or modeling tool rather than a ray tracing demo
