采用C++11编写的基于物理的图象渲染器：Tungsten
Tungsten: 一个采用C++11编写的基于物理的图象渲染器。这款软件在2014年早期获得了在苏黎世联邦理工学院图象综合渲染器竞赛中获得第一名。
Feature list
Below is an incomplete list of the features implemented in the renderer. If you're really interested, there is also the detailed (boring, outdated) project report from summer 2014.
Material models
- Smooth coat (varnish on top of configurable material)
- Microfacet dielectric (GGX, Beckmann or Phong)
- Microfacet conductor (GGX, Beckmann or Phong)
- Thin-sheet dielectric
- Oren-Nayar
- Plastic
- Smooth dielectric
- Smooth conductor
- Alpha mapped surfaces
- Bump mapped surfaces
- Mixed (blend between two materials)
- Lambert
- Phong
In many instances, material parameters can also be specified via texture.
Shapes
- Triangle meshes
- Bspline curves (ribbons, cylinders, half-cylinders, camera-facing flats)
- Spheres
- Quads
- Disks
- Infinite spheres (for environment maps)
- Infinite spherical caps (for sun-like emitters)
Camera model
- Depth of field
- Shaped Bokeh (configurable via texture)
- Cateye effect
- Chromatic aberration
- Tone mapping (Filmic, Reinhard, Gamma)
Input formats
- Meshes: OBJ, WO3
- Textures: HDR, JPG, PNG, TGA, BMP, GIF
