Path-tracing in Godot 4 using vulkan compute shaders

godot-path-tracing

Simple pathtracing implementation in Godot 4. With free look camera at 20-40 fps (gtx 1050 mobile)

You can use godot editor to describe scenes: place the camera, add sphere/plane, set their colors etc.

Ported c++ code from https://www.kevinbeason.com/smallpt

Incorrect rendering on 4.0.rc1

OS: Fedora 37
GPU: NVIDIA GeForce RTX 4090 (NVIDIA 525.85.01)

Rendering appears mostly green, even though pathtracing does work technically:

Ray depth 5 (default)

Ray depth 1

Note that I've also had to make an array of RDUniforms untyped and change class_name Plane to class_name Plane2 to get the GDScript code to work without errors.
