Integrated Network Rendering
- Render a single image efficiently across multiple machines - Needs only a TCP/IP network, such as a typical Local Area Network. (LAN)
Participating Media
- Sub-Surface Scattering (SSS)
- Unbiased multiple scattering - for the ultimate in realistic SSS.
- Wavelength dependent scattering and absorption coefficients.
- Henyey-Greenstein, Uniform, Rayleigh phase functions.
- Atmospheric scattering model including Mie and Rayleigh scattering.
Full Spectral Rendering
- All light transport calculations use spectral colour instead of RGB colour.
- Rendering parameters, such as material colours, accept arbitrary spectra instead of RGB triplets.
Support for Complex Geometry
- Support for large meshes. (Tested with 28 million triangle model)
- Instancing support - A mesh can be repeated in a scene thousands of times with only minor additional memory usage.
Physical Camera Model
- Realistic aperture for accurate depth-of-field simulation.
- Focal distance - automatic or manual.
- Can set sensor width and exposure time.
Advanced Tone Mapping
- Multiple methods for tone mapping a HDR image to a LDR image.
- Reinhard tone mapping for fully automatic tone mapping.
- Camera tone mapping for accurate simulation of real camera films.
