OPath currently supports a variety of features, including but not limited to:
- Spectral rendering
- Rather than the standard RGB component model, OPath uses a full spectral approximation (although this is optional at compile time).
- Multiple rendering algorithms
- Distribution ray tracing, path tracing and Instant Global Illumination are supported. Photon mapping is planned soon.
- Physically based materials
- A variety of BSDFs are supported.
