Nuance is a simple path tracer for nim. It is currently in development.
I built this to learn about both Nim and path tracing!
- Material support for glass, metal & lambertian materials
- Primitive support for spheres, triangle meshes, cylinders and dics
- Texture support, including images
- Parallelised rendering pipeline
- Scene definition via a .toml style file
- Basic model support through .obj files
- Simple bounding volume hierarchy for collision detection speed up
nuance is run as a CLI:
