- Sony Pictures Imageworks open sourced Open Shading Language, Field3D, Alembic and OpenColorIO.
- Pixar opensourced OpenSubDiv
- Disney opensourced Ptex, BRDF Explorer, SeExpr and Partio
- Dreamworks open sourced OpenVDB
I wouldn't be too suprised if we would see an open source renderer within the next 10 years, especially if SPI is going to replace their in-house version of the Arnold renderer, as open source software has been extremely successful for SPI.
The open sourcing of C and C++ libraries in CG is awesome. But that is skewing the original point. Studios aren't going to replace their interfaces with blender and they aren't going to open source their own creation software. Most studios use a combination of maya, katana, 3ds, houdini and vray.
What you listed are mostly formats that are beneficial to everyone to share (and don't forget OpenExr). OpenSubdiv lets others match renderman's subdivision. Also Imageworks' open source push can largely be traced back to Rob Bredow I believe.
