A small but rich language for programmable shading in advanced renderers and other applications
Open Shading Language (OSL) is a small but rich language for programmable shading in advanced renderers and other applications, ideal for describing materials, lights, displacement, and pattern generation.
OSL was originally developed by Sony Pictures Imageworks for use in its in- house renderer used for feature film animation and visual effects, released as open source so it could be used by other visual effects and animation studios and rendering software vendors. Now it's the de facto standard shading language for VFX and animated features, used across the industry in many commercial and studio- proprietary renderers. Because of this, the work on OSL received an Academy Award for Technical Achievement in 2017.

- update to 1.12.10.0:
+ feat(testrender): Modify testrender so that it correctly sets
raytype to "camera" for camera rays, "shadow" for shadow rays,
and "diffuse" for all secondary rays. Also rerun the shades for
background shader group on the camera rays rather than use the
cached map. This helps the MaterialX project use testrender for
certain unit tests and verification. #1648 #1649
+ feat: Expose llvm groupdata size as a shadergroup attribute
"llvm_groupdata_size". #1642
+ fix: Crash could result from uncaught exception in OpenColorIO
when calling transformc with derivatives for color spaces that
require OCIO. #1646
+ fix: certain uses of fmod() in shaders could fail to generate
LLVM code correctly, due to a missing implementation for the
fmod(triple,float) varieties. #1643
+ build: Change snprintf formatting to satisfy some compilers.
#1640
+ CI: Fix broken Mac ci. #1647
- Force build with LLVM 15 on TW
- Add a BuildIgnore for clang-tools, that would render the llvm15
containment ineffective otherwise (by depending on clang16).
- Add 4G memory _constraints
