Open Shading Language Continues Making Progress
Phoronix: Open Shading Language Continues Making Progress
Sony released the Open Shading Language in 2010 as "a small but rich language for programmable shading in advanced renderers and other applications." This simply wasn't a code drop of some no longer useful code to try to spark them some positive publicity, but OSL has kept advancing as an open-source shading language...
Before anyone asks, no, this is not a competitor to OpenGL/GLSL or Direct3D/HLSL. It's a shading language intended for high-fidelity rendering in movies using huge rendering farms comprised of many thousands of full unrestricted CPU cores with terabytes of memory, not for efficient rendering on a (GP)GPU and its thousand of severely restricted cores and a couple gigabytes of memory (and the severe limitations imposed on accessing that memory from those GPU cores).
