Re: OSL - branding
Zap Andersson
I agree completely with Larrys opinions (i.e. mostly liking 3, or enjoying saying "the S means hope" about 4), including the "poor me" part if we are gonna reproduce #3 in OSL code, LOL. :P The beauty of my logo - if I may say so myself, LOL - is that it's a pretty short snippet of OSL, generating a "fairly nice" logo, with code that I at least hope some people look at and go "how does this even work". :) Anything not strictly based in math will (as code goes) look a lot less... elegant, full of if-statements and hard-coded numbers for "which thing goes where". While that is fine, it spoils the magic a little bit. But then again, maybe we shouldn't design a logo based on the elegance of the code. Or.... us being us ... should we? :) I am, obviously, 20000% biased, and bow to the wisdom of the group. /Z On Thu, Mar 18, 2021 at 8:06 AM Larry Gritz <lg@...> wrote:

Re: OSL - branding
Larry Gritz
I'm also leaning hard against overlapping or unclear letters, it just doesn't work for me. And I think that after prior discussions, Mario had me convinced that we should go more abstract, not try to make the logo BE the words or the letters.
I think 3 and 4 are my favourites of this set. Is 3 too "busy"? I know that the lines are alluding to the "connection" idea, but to me it reads more as "circuitry" rather than the "shading" that I got clearly from some of the earlier hatching or halftone styles like the middle and upper right examples in section 3 of your Feb 18 email, or Zap's shader. But I could definitely be convinced if people like this variant. (Poor Zap, though, getting those wires exactly right in the shader will be tricky.) 4 also has potential. I'm less bothered than Chris about the missing L, I definitely get the O and S, and I don't mind the superman bit. (And you all know how much we're looking forward to saying "It's not an S" whenever somebody asks us about it.)
5 All I can think of is that the gradients might be hard to reproduce in some media and that it might not be readable small.

Re: OSL - branding
I'm really liking #3 -- ties into the shaded sphere and nodegraph ideas at the same time (and even half-tone dots to some extent). #1 reads a bit too much like CSL for me #2 I like the leftmost one, though its getting a bit abstract and i'm not sure about how well it reads over a dark background #3 Definitely my favorite so far (both color and black&white versions) #4 Without the L it's hard to read the circle as an O - so it feels more like a superman type of S logo. #5 The depth effect is cool, though I'd worry that it would look too different to other industry logos and the "cut out hole" effect might not work in all contexts. The O and L also feel a bit squeezed and off-balance. Overall the designs using the letters never quite click for me. Like you said before, it's a hard combination of letters to make work. But I'm liking where #3 is going. Thanks for these - really nice work! Hey, |

OK, let's talk about this for the first 20 minutes at tomorrow's meeting.
Zap, can you let Jonathan (and anybody else coming *only* for the BSDF discussion) know that it's fine for them to arrive 15-20 minutes after the meeting start if they aren't interested in sitting through the logo discussion? Thanks.

OSL - branding
mariovario@...
Hey,
Since I can't write OSL code and even if I could I think that we should design the logo then transfer it to OSL. I find vector graphics software way faster and nimble with graphics than code... Anyhow... Here is my next iteration of the brand experiments. This time it is all about shading... This is the main idea I was trying to express here. Have look and comment. PDF attached. m |

Re: OSL getmessage/setmessage
elizabeth.bonnefoy@...
Hi Chris Thank you for your answer! To give you more context, we try to read volumetric files from OpenVDB via texture3D(), so we need to provide it some arguments like: - The name of the VDB file, which can hold many grids - The name of the grid we want to read: "Density", "Heat", "LevelSet", ... - Some lookup options, like using multi-resolution or not, some multiplicative scale on the filter size, access to the min/max grid useful for the tracking algorithm... - Eventually the name of some metadata we would like to retrieve from the file
Actually it's ok, because as you said it, there is always an argument of texture3D we can use to provide additional informations, even if this could lead to several call to texture3D() for the same file. Thank you again for your time. Kind regards, Zab |

Re: OCIO via OIIO in OSL (ACRONYM SOUP :) )
Larry Gritz
Um, the texture lookups themselves are not color managed. They are assuming that you have done your color management in the "maketx" process, so the textures themselves are in your canonical linear rendering color space.

OCIO via OIIO in OSL (ACRONYM SOUP :) )
Zap Andersson
So if we compile OIIO with OCIO2 for OSL (normal people are gonna wanter WTH I'm talking about :) ) ... is there some way to pass along paramters to OIIO through the OSL texture() call?
I.e. if I say I want a raw lookup (non color managed), is there a parameter for this? To give the color space? Do something? /Z |

Standardizing OSL Closures - The Topic(tm)
Zap Andersson
So as mentioned on last weeks OSL TSC meeting, there is a desire to have a default set of closures in OSL that can be supported natively, and on the meeting we said that the set used by MaterialX is a good candidate set. I've invited Jonatan Stone (Lucasfilm) and Niklas Harrysson (Autodesk) to next TSC meeting to discuss the topic a bit. Both are key contributor to the PBR stuff in MaterialX and are both excited at this idea. There are some interesting implementation wrinkles to think about, which is why these gentlemen are ideal to help us solve this. Some "light reading" while we await next meeting: http://www.materialx.org/assets/MaterialX.v1.38.PBRSpec.pdf Also this talk by Niklas & Jonathan from SIGGRAPH is relevant viewing https://www.youtube.com/watch?v=6Lz2wq1tA20 (Coming form this course https://blog.selfshadow.com/publications/s2020-shading-course/ )

Re: OSL getmessage/setmessage
Hi Elizabeth,
I think getmessage is probably not the easiest way forward here. Generally we try to avoid calls that require holding onto state as much as possible (the trace call and getmessage being notable exceptions). In fact you probably noticed already that only the "trace" related getmessage calls will make it to render services. There isn't currently a form of setmessage that will invoke anything on the renderer services side. It's a bit hard to say without knowing all the details of your use case - but perhaps you could take advantage of the "firstchannel" or "subimage" arguments to the texture call? This would allow you to return different values for different calls to texture3d. Or is there something about your use case that requires you to perform all the work in a single call to texture3d? Can you give us a few more details about what you would like to pass in and out of the texture3d call? Cheers, Chris On Wed, Mar 3, 2021 at 8:30 AM <elizabeth.bonnefoy@...> wrote:

Re: OSL - branding
Very nice! A possible tweak: Have the dark regions of the sphere form an “S” shape, such as, a crescent in both the lower-right and the upper-left, connecting in the middle somehow. Then you have both an “O” and an “S”, as well as the concept of 3D shading.

Of course, in the spirit of "eat your own dogfood" (or was it "you are what you eat"?), of course the OSL LOGO should be in OSL |
