This article describes some terms and solutions used in 3D visualization industry.
ATF
Autodesk translation framework, framework for data exchange.
BRDF
Bidirectional reflectance distribution function.
BSDF
Bidirectional scattering distribution function. Used as generalization for reflectance and transmittance, eg BSDF = BRDF + BTDF.
BTDF
Bidirectional transmittance distribution function.
Hydra (HD)
Framework to transport live scene graph data to renderer (originally USD to OpenGL render engine). Open source, developed by Pixar.
OGS
Open graphics system, viewport renderer used in Autodesk software (3ds Max, Maya, AutoCAD, Inventor, Revit, Fusion, Infraworks, Navisworks, Recap, etc).
Not to be confused with OpenSceneGraph (OSG).
Radiance
Radiant flux emitted, reflected, transmitted, or received by a given surface, per unit solid angle per unit projected area. Unit: watt per steradian per square metre (W·sr−1·m−2)
