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.
In Renderman is OSL also an important module. It is here modified for better Intel AVX2 and AVX-512 advanced vector extension support with doubled performance. SIMD OSL is the product of this Development for Intel SIMD AVX2 and AVX-512 Hardware (Haswell and newer). AMD CPU Hardware with AVX2 support like Ryzen with Zen Architecture can also use this extension. [5][6]
Home of Development is GitHub. Actual Version is 1.11.14 released 2021-05-10. [7]
Future release 1.12 will support C++14 as default. OpenImageIO support will be dropped for 2.0 with support of 2.1-2.3. SIMD Batch shader Mode and OptiX support are in development and experimental. CUDA 11 and OptiX 7.1 are here supported levels.[8]
Movies
Many movies made in 2012 or later have used OSL,[9] including:
