Open Shading Language

Open Shading Language (OSL) is a shading language developed by Sony Pictures Imageworks for use in its Arnold Renderer. It is also supported by Illumination Research's 3Delight renderer,[1] Otoy's Octane Render,[2] V-Ray 3,[3] and by the Cycles render engine in Blender (starting with Blender 2.65).[4] OSL's surface and volume shaders define how surfaces or volumes scatter light in a way that allows for importance sampling; thus, it is well suited for physically-based renderers that support ray tracing and global illumination.

Not to be confused with OpenGL Shading Language.

Movies

Many movies made in 2012 or later have used OSL,[5] including

gollark: I live in the Britainian realms, though, which are reasonably temperate most of the time, so I have the door open and stuff now.
gollark: Doesn't mean not having those is nice.
gollark: Humans have lived without... air conditioning, indoor toilets, reasonably reliable food supplies, shoes, and a lot of other things.
gollark: None of this "working for days without compiling".
gollark: When I work on webthings, I have autoreloading set up so I can change something and instantly see the difference, and my changes are immediately reflected.
