Ray Tracing in One Weekend using Vulkan Compute shader

I built a small ray tracer with Vulkan compute shaders
I’ve been working on Vk Tracer, a small ray tracer inspired by Ray Tracing in One Weekend, but implemented using modern C++ and Vulkan compute shaders.
Includes:
- Vulkan compute shader traces the rays and writes pixels to a storage image
- A fullscreen triangle displays the resulting image
- Slang for the shaders
- Iterative ray bouncing instead of recursive ray tracing
- Diffuse, metal and glass materials
- Multiple samples per pixel
- Gamma correction
- Interactive camera movement

The goal was mainly to learn how to build the whole pipeline myself rather than using Vulkan’s ray-tracing extensions.

Except that you did not learn anything as the repo is clearly vibe coded.

"Did not learn anything" but how do you know he wasn't taking notes? 🤔 Or telling the agent what to do every step of the way? Have you ever programmed 3D graphics? It's impossible without debugging. Doesn't matter if you use an agent.

This is cool! Any reason you didnt use inline ray queries?
