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 1.12.6.2:
For details see
https://github.com/AcademySoftwareFoundation/OpenShadingLanguage/releases/tag/v1.12.6.2
* Batch shading: A fully operational "batch shading" support when
using CPUs supporting the Intel AVX2 or AVX512 instruction set
architectures, allows shading 8 or 16 points at a time,
accelerated by using SIMD instructions. (Changes contributed
by Intel.)
* OptiX: A reasonable subset of the OSL language can run on
NVIDIA GPUs for Cuda or OptiX-based renderers.
* Standardized material closures: Synchronize with MaterialX on
a minimum standard set of material closures. This is reflected
in both the OSL spec as well as reference implementations of
those closures in testrender.
- Remove subpackage with MaterialX shaders. These were already
deprecated for some time, instead ones from upstream
MaterialX project should be used.
- Drop upstream 0001-Fix-compatibility-with-LLVM-14.patch
