Raytracer

A GPU raytracer created to explore Vulkan, compute shaders, and the basics of ray tracing. It uses Vulkan’s compute shaders to accelerate ray tracing computations on the GPU, enabling real-time rendering of scenes with realistic lighting. The project also integrates ImGui for a simple user interface that allows interactive control over the camera and rendering settings.
