BSDF Processor is an application for interactive visualization of BSDF (bidirectional scattering distribution function). The user can investigate and edit BRDF (bidirectional reflectance distribution function) and BTDF (bidirectional transmittance distribution function). Basic functions are implemented using libbsdf.
- 3D plot using incoming angles and multiple display modes
- Real-time rendering with directional and environment lighting
- Table view of sample points
- Property and characteristic views
- Simple editor
- File loaders and exporters for multiple formats
- BRDF/BTDF generators using reflectance/transmittance models
BSDF Processor can load the following formats:
| Format | Extension | Measured Data |
|---|---|---|
| Surface Scattering Distribution Data | .ssdd | |
| Integra Diffuse Distribution | .ddr, .ddt | |
| Integra Specular Distribution | .sdr, .sdt | |
| Zemax BSDF | .bsdf | RPC Photonics |
| LightTools BSDF | .bsdf | |
| ASTM E1392-96(2002) | .astm | Cornell University |
| MERL BRDF | .binary | MERL |
BSDF Processor can export the following formats:
| Format | Extension |
|---|---|
| Surface Scattering Distribution Data | .ssdd |
| Integra Diffuse Distribution | .ddr, .ddt |

BSDF Processor uses the following open source libraries:
- libbsdf
- Eigen 3
- OpenSceneGraph (v3.6.4 is recommended instead of v3.6.5 to avoid the issue of osgText::FadeText)
- Qt 5
CMake is used as the build system.
Search paths for libraries are set through CMake variables: LIBBSDF_DIR, OSG_DIR, Eigen3_DIR, and Qt5_DIR.
