OSL v1.11.17.0 release
Larry Gritz
We have tagged v1.11.17.0 and updated the "release" branch marker to this point, as the latest supported production release of OSL. This is guaranteed to be API, ABI, and link backward-compatible with prior 1.11.* releases.
Release 1.11.17.0 -- 7 Jan 2022 (compared to 1.11.16.0) ------------------------------------------------------- * Fix in runtime optimizer where tracking of messages and unknown messages relied on uninitialized variables. #1447 * Minor changes related to OpenColorIO changing their master branch name to "main". #1431 * Testing: Get texture3d tests operational again. #1437 * Docs: Fix missing "errormessage" explanation for environment() and texture3d(). #1442 * Build/cmake fixes: Make PROJECT_VERSION_RELEASE_TYPE and OSL_SUPPORTED_RELEASE be cache strings, so they can be overridden; change OSL_IS_SUBPROJECT to PROJECT_IS_TOP_LEVEL (and change its sense) to match CMake 21+ behavior; add a TIME_COMMANDS option to help debug performance of the build. #1443 -- Larry Gritz lg@larrygritz.com

Re: Vector property missing when translating RSL to OSL
Larry Gritz
In the original RSL, there were no structures, and "." was appropriated to be the dot product operator! (We later came to regret that once the utility of structures was evident.) So I think what you want is thOutPrime = asin(dot(ssOutDir, axis)); (This was the second response I wrote to your email, the first being just totally perplexed and begging to see the declaration ofssOutDir. Then I started thinking about the "asin" and why anybody would ever take the component-by-component asin of a vector, that made no sense. Then just before I hit "send", I realized that asin is useful for computing the angle between two vectors from their dot product... and it all fell into place.)

Vector property missing when translating RSL to OSL
anders.steen98@...
This was originally posted in the RenderMan forum, but I think someone here might know the answer, so I'll try posting here.
where ssOutDir is a vector and thOutPrime is a float.

Re: u,v barycentric coordinates vs. map coords
philippe.groarke@...
It seems OSL is a bit less renderer agnostic than I was expecting. Is cross-DCC eval a goal of OSL, or are these differences expected/accepted? I couldn't find any info on an official way to get the current renderer, but that would help if OSL is expected to have these kinds of discrepancies. I'm thinking a standardized way to ifdef according to renderer (not sure how that would be standardized). Or even a runtime call would help for these edge cases. @Chris To answer your question. Currently I'm experimenting with interpolating tangents in screen space (tbd if it ever works). This may be an Arnold thing, but its tangents (dpdu, dpdv) are per triangle. I need this to compute a surface curvature map using the jacobian eigenvalues. Overall I'd say barycentric coords are very useful for any type of screen space interpolation.
