This article describes some terms and solutions used in 3D visualization industry.

ART

Autodesk RayTracer, physically-based render engine for 3ds Max, AutoCAD, Revit, etc. Uses path tracing on CPUs for rendering.

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, e.g. 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.

Irradiance

Radiant flux received by a surface per unit area. The unit of irradiance is the watt per square metre (W⋅m−2).

Mental Ray

Deprecated ray tracing renderer by NVIDIA. Were used in older versions of 3ds Max, Maya, Revit, Softimage, etc. Replaced by Arnold.

MetaSL

Outdated shading language which were used in 3ds Max (before 2016) and Mental Mill software.

Nitrous

3ds Max viewport system.

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. The unit of radiance is watt per steradian per square metre (W·sr−1·m−2).

RapidRT

Render engine, aka Autodesk RayTracer (ART).

Stingray

A discontinued 3D game engine. Also used as 3ds Max Interactive plugin for older 3ds Max. Node system based on Stingray PBS is supported in 3ds Max, Maya (created via ShaderFX editor).
