As you probably know, some functionality (including pointcloud_search) is implemented by callbacks to the RendererServices object supplied by the renderer itself. Each renderer makes a derived class f

Hi, sorry for letting this sit for a long time without a reply, but I'm still not sure I understand what you're trying to do. If you are tracing rays in some order, when tracing one particular ray, yo

Good news -- ASWF has been accepted into the Google Summer of Code (GSoC) as a mentoring organization. We require student applicants to have an accepted PR to any project they wish to apply to, as a p

Can you tell us more about what you were TRYING to do? Not just the "what", but I really mean the "why." What task were you trying to accomplish, for which you hypothesized that the solution was needi

I think that's the point of confusion. P is one point, it is not a "set of points." The programming model (how you think of the shader operating) is that you are shading one point at a time. That's al

I'm not sure what you mean by the "coordinate of P" or what you mean by "an array from a global variable." Can you explain in more detail, or maybe show a few lines of code illustrating what you want

OK, it is decided. Let's cancel for today. -- lg -- Larry Gritz lg@...

OSL TSC attendees -- I'd like to cancel today's meeting if there are no pressing matters that need a live call today. Chris Kulla has jury duty, and I was going to push on without him, but just this m

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

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 w

Congrats to Sam and team! This was a great keynote this morning, beautiful work. Thanks for the gracious shout-outs to OSL and MaterialX, it is appreciated. -- lg -- Larry Gritz lg@...

OK, the deed is done: OSL's "master" branch has been renamed to "main". There are three things you need to do: 1. If you have a fork of OSL on GitHub, when you visit the fork on the web, GitHub will h

Following in the footsteps of git itself, GitHub, GitLab, OpenColorIO, and likely the rest of the ASWF projects fairly soon, the OSL technical steering committee has decided to go ahead with renaming

There's an OSL mode for SublimeText (https://packagecontrol.io/packages/Open%20Shading%20Language), which is a TextMate-style editor. I don't know how good this language mode is for ST, but I wonder i

Oh yeah, that's a big one, thanks for the reminder. So it looks like, coincidentally, both of our next two scheduled Thursdays are going to be problematic. Let's consider the 25th cancelled for sure,

Our next TSC meeting is scheduled for Nov 11 -- that's a holiday where I live and work in Canada, and maybe other places, too? Basic choices are: 1. Lots of people not working and/or nobody has anythi

Today we tagged "v1.11.16.0" as the latest patch release in the 1.11 family, guaranteed to be back-compatible with both API and ABI compared to prior 1.11 releases. The "release" branch marker has als

When dinosaurs roamed the earth, OIIO's TextureSystem API assumed it might be used for many different types of renderers, and so we had placeholders for shadow mapping calls (and related parameters in

Wondering if anybody would object to the following changes to minimum dependencies -- only for master branch going forward and the NEXT major release of OSL (obviously not dropping support from releas
