Now's the time to make better ICC profiles ?!

The current set of ICC profiles (I looked at the ones created for ACES
1.0.3) has some short-comings in current workflows and that we should
consider addressing. Here's my list:

- The PCS space is Lab. This is too small for current projects. Lab is
smaller than Rec. 2020. Several corners of the 202 cube get clipped by Lab.

Whilst I'm don't think OCIO has perfect ICC support, I'm not sure
what you propose is even possible. Last time I read the ICC
specifications the only options for profile connection space are
L*a*b* and XYZ, neither of which have any limits which prevent you
using 2020 gamut - I certainly have profiles using ACES AP1 which is
wider than 2020. Could you describe what you are trying to do?

As a random guess are you perhaps relying on the inbuilt sRGB display
profile, when really you need a wider one?

ACES 1.0.2 and 1.0.3 configs in the Sony repo

Haarm-Pieter Duiker <li...@...>
 

Hello OCIO-ers,

The ACES 1.0.2 and 1.0.3 configs were accepted into the main OCIO repo this weekend.

The 1.0.3 config includes the latest 1.0.3 transforms, including the sRGB Output Transform, some updates to organization that should be helpful to newcomers and updates to the Input Transforms for ARRI, Canon and Red.

One thing to note, the names of a few colorspaces changed as follow:
  • 'ADX - ADX10' became 'Input - ADX - ADX10'
  • 'ADX - ADX16' became 'Input - ADX - ADX16'
  • 'Input - ARRI - Linear - ARRI Wide Gamut' became 'Input - ARRI - Linear - ALEXA Wide Gamut'
  • The 'logc3eiXXX_arriwide' spaces became 'logc3eiXXX_alexawide'
Please post OCIO-specific issues here and ACES-specific issues on acescentral.com

Thanks!
HP

Thanks, yeah I should have linked the PR in the post. I'll try and get more eyes on that to test, though I'm sure it's fine, then we can pull that through to get things kicked off.

As for Labels, I'd just like to get a better organizational structure that guides users attention a little better. My gut feeling is pushing towards a slimmed down version of this: https://medium.com/@dave_lunny/sane-github-labels-c5d2e6004b63#.3kx74xshg


Re: OCIO - Path Forward

dbr/Ben <dbr....@...>
 

This all sounds good to me!

I would be happy to help out auditing/tagging the issues in GitHub. 

The current labels seem fairly reasonable to me - "feature" for new things, "bug" for bugs, internal for non-user-impacting things, a label to flag API breaking changes, and "deferred" for future things. I'd probably add tags for performance improvements, docs, and build related issues. Then along side these, maybe tags for tag "easy" quick-to-fix issues, low/high priority tags)

Regarding CI, There is a pull request to fix up the TravisCI config (#415). It would also be worth investigating Appveyor to test on Windows also

Hello all, and happy new year!

I'd like to start a formal discussion around the steps we will take to give OCIO a breath of life. Hopefully we can work to make 2017 a year of progress. So in that spirit I'd like to layout a general game plan for comment and discussion.

General Notes:
  • Reading through our last discussion I found it troubling that due to the stalled public development, conversations and progress seemed to have moved behind closed doors. To facilitate openness I advise all contributors to relegate conversation to either the GitHub issues or this forum. I have created an OpenColorIO Slack channel if there needs to be quick group conversation among contributors, but the majority of conversation should be relegated to this forum.
  • I have been granted ownership to the GitHub repo, and can accomplish administrative tasks as necessary. I do not intend to accept Pull Requests in isolation, both due to the need for public discourse and my unfamiliarity with the codebase.
  • Development should continue in a "master-only" fashion, based on the previous branch/merge patterns and at the suggestion of Larry Gritz

Game Plan:

  • Organization
    • Project Owners
      • This is no slight to the current owners of OCIO, but would it be worth it to revisit the current owners and identify their level of involvement moving forward (based on interest and free time available)? It could be beneficial to add vocal / active developers to the helm of the project. Discussion welcomed.
    • Issues
      • Need to create a better issue labeling scheme, and need to maintain it's use. Suggestions welcome.
      • Are issues irrelevant / duplicates?
      • Do PRs solve specific issues?
      • Asses difficulty in solving
    • Pull Requests
      • Are they still relevant?
      • Rank in order of usefulness
      • Determine order of integration
  • Repository
    • Continuous Integration
      • In order to begin pulling a larger volume of Pull Requests, we need to update the CI system in use.
      • Alongside this is a reevaluation of the OCIO unit tests
    • Make private forks public
      • Address private forks with additional features (Dennis Adams, Mark Boorer, etc.)
      • Get them posted publicly, work into pull request
  • Road to 2.0
    • What are the dream requests?
    • How do we want to interact with OCIO in 5 years?
    • What movements on the horizon do we need to begin working towards?
    • What features would improve adoption in modern software?
Order of Attack:
  • Issue Labels
  • Easy PR with greatest image quality impact
  • Website + Documentation
    • Up to date? Documentation still relevant?
    • Website on version 1.0.8
  • Continuous Integration
  • PR review
  • Issue solving
  • Live, Long and Prosper

Please join me in conversation about the future of OCIO! All of the above is open to suggestion and critique.

A) Providing metadata on the chromaticities for each Display cluster, or possibly per View?
B) Providing metadata on the reference chromaticities.
C) Provide some form of metadata that differentiates the transfer function portion of a view transform from any other colorimetric transforms. This would be needed for colour pickers and other things, where one needs to know the colorimetry of the reference and the destination, as well as how to apply *only* the transfer function to the UI element, post transform. Gradient UIs, color pickers, coloured sliders, etc.

Troy, would you be able to wrap this into an Issue on GH? With the coming addition of labels, this will be classified as a feature request.

On a practical "get things done with the library" sense, it would be excellent to deal with OCIO for colour managing UI elements.

Having spent plenty of time ramming into the problems, I believe that can be elegantly accomplished by:

A) Providing metadata on the chromaticities for each Display cluster, or possibly per View?
B) Providing metadata on the reference chromaticities.
C) Provide some form of metadata that differentiates the transfer function portion of a view transform from any other colorimetric transforms.

Gradient UIs, color pickers, coloured sliders, etc.

Many transforms are going to be of the transfer function variety, and it makes sense to tackle UI in the least invasive manner possible, hence limiting the metadata to the fewest possible areas makes sense? Per transform seems overkill unless a sane metadata structure can be arrived at that wraps up the needs.

Re: LUT for linear exr to rec709

Sean Cooper <se...@...>
 

Hi Meiwa,

It's a bit hard to remotely debug from the info you've provided, but the general answer is that you'd want to bring your Linear source (presumably in Arri Wide Gamut primaries) into a V3LogC space. Depending on the tools at your disposal you should be able to do this in most grading applications and in Nuke's native "colorspace" node, or uses OCIO's ACES 1.0.1 config. Then use the ARRI Lut Generator, but coming from LogC source instead of Sensor Linear.

If you give a little more info I could try to shape my answer a little better.

Is that because there is difference between "scene linear" and "normalized sensor linear"?

The problem that we currently have is that 3D software ( in our case Maya rendering with Vray) renders out linear exr files. In order to use any of the LUT that are generated by the Arri LUT generator, (https://www.arri.com/camera/alexa/tools/lut_generator/) I need to apply a "pre" LUT to convert my linear renders into logc images that the arri LUT is expecting. Does anyone know how I can go about doing that?

Any advice greatfully recieved.

No, 64 bit only.

I used the default cmake settings, though I did run cmake and build with cygwin in my path (so "patch" would work when building tinyxml).

I'll look into the v0 vs v1 issue - that looks like it may be the culprit.

Are you using the proper generated headers? Are you overriding so
version in CMake?

All the symbols are in OpenColorIO::v0, and I would expect them to
be in v1 (corresponding to the major version).

See https://github.com/imageworks/OpenColorIO/blob/master/export/OpenColorIO/OpenColorABI.h.in
<https://github.com/imageworks/OpenColorIO/blob/master/export/OpenColorIO/OpenColorABI.h.in>

set(SOVERSION ${OCIO_VERSION_MAJOR}CACHESTRING "Set the SO version
in the SO name of the output library")

I'm in the twilight zone today. After a bad merge from
Mac->Windows, my application will no longer link against the
shared OpenColorIO.lib on Windows, using Visual Studio 2012.
This is the exact same set of headers and .lib I've been using
for over a year.

The link errors are all like this one:

error LNK2019: unresolved external symbol "__declspec(dllimport)
public: static int __cdecl
OpenColorIO::v0::FileTransform::getNumFormats(void)"
(__imp_?getNumFormats@FileTransform@v0@OpenColorIO@@SAHXZ)

and there seems to be an error for every OCIO function or
definition I make use of, including:

error LNK2001: unresolved external symbol "__declspec(dllimport)
char const * const OpenColorIO::v0::ROLE_DATA"
(__imp_?ROLE_DATA@v0@OpenColorIO@@3PEBDEB)
error LNK2001: unresolved external symbol "__declspec(dllimport)
char const * const OpenColorIO::v0::ROLE_COLOR_PICKING"
(__imp_?ROLE_COLOR_PICKING@v0@OpenColorIO@@3PEBDEB)
error LNK2001: unresolved external symbol "__declspec(dllimport)
char const * const OpenColorIO::v0::ROLE_SCENE_LINEAR"
(__imp_?ROLE_SCENE_LINEAR@v0@OpenColorIO@@3PEBDEB)

Just for fun I cloned the current OCIO master branch, ran cmake
on it, and rebuilt. I did have to make one change to
OpenColorABI.h, and that is to get it to use <memory> and
std::shared_ptr instead of boost or the tr1 stuff:

#elif defined(_LIBCPP_VERSION) || defined(WIN32)
#include <memory>
#define OCIO_SHARED_PTR std::shared_ptr
#define OCIO_DYNAMIC_POINTER_CAST std::dynamic_pointer_cast

But that's a minor change.

I'm linking with OpenColorIO.lib, but the linker is acting like
nothing is being exported from it.

Has anyone else experienced anything like this?
