Convert the xy coordinates to XYZ, with red being the first column, then green, then blue. That forms a 3x3 matrix for taking linearized RGB to the XYZ domain. From there you would need to perform a c

Hi, This is likely a very old request. I am charged with setting up a global config for a new startup. I am basing the .ocio on aces1.0.3 I'm confused on how to customise profiles, looks etc ... I do

Hi All, I'm a new to both Nuke and OCIO. For some reason, I need to develop a nuke OP similar to OCIOFileTransform. But when I add just one simple line such as "OCIO::GetCurrentConfig()", I got a cras

Hi, For some reason, I need to write a pixelOp similar to OCIOFileTransform with OCIO API. But when I add just one simple line such as "OCIO::GetCurrentConfig()", I got a crash with the terrible "Pure

Hi all, I would like to know if OCIO java public interface is used? and should be maintained ? OCIO currently supports three public interfaces: 1) The native C++, 2) The Python interface (built on top

Hello all, With the help of our lovely contributors, we have just set up the 1.1.0 release branch. This is currently regarded as a Release Candidate since the official 1.1.0 tag has not been assigned

Hello all, With a little bit of movement on the OCIO repo working towards addressing the most egregious image-quality-effecting bugs, we need to look to locking off to a 1.0.10 to help our users, and

I would really like to see OCIO support .cdl files in addition to .cc and .ccc as an direct input for the FileTransform and CDLTransform. Of course there are ways and tools like cdl_convert to convert

FileTransform will attempt to load the specified lut formats, if the initial read fails. I also had to make some of the 3D lut loaders use stricter parsing as they now get called (in error conditions)

The latter mostly, most VFX studios that maintain the project don't actively use After Effects so it's not usually on our minds. So its also a question of, if its broken who cares enough to do somethi

Currently, I am using OCIO with a mixed CPU/GPU pipeline. Luts are 4 float colors which get fed like: // // Compute lutMin, lutMax, and scale and offset // values, lutM and lutT, so that // // lutM *

I have a GL Lut that is not created with OCIO. Instead an initial identity lut is created and this lut is passed on to the gfx card by my own code. So long, so good. However, this lut is not a perf

https://sourceforge.net/projects/mrviewer/files/v3.8.4 This version of mrViewer is the first to add some support for OCIO. Please add this software to the compatible list. Thank you.

Hi there, I'm taking a passing glance at colour management in After Effects and I found the OCIO plugin maintained as part of the OCIO Github project. https://github.com/imageworks/OpenColorIO/tree/ma

For those of you attending SIGGRAPH 2017 (conference pass required) in Los Angeles, we will be hosting a "Birds of a Feather" event for users and developers of OpenColorIO to get together and discuss

Hi, I know it is an old question but I could not find a working solution. Is there a walkthrough to build OCIO including PyOpenColorIO on Windows? Or something precompiled that might work? My current

I'm trying to add a colorspace that is using a $SHOT env. It all works as expected if the shot lut exist. If the shot lut does not exist an error is thrown: The specified file reference '${SHOT}.cube'

Hi folks, A feature that our artists fought long and hard to have is the ability to change shots from within their software, without going back to the shell and doing a "setshot" (which sets up variou

Is it possible to use ocio to crest an icc profile that can fully define a color space with XYZ PCS like a classic srgb or adobe rgb profile? What getting at is that I've defined a device color space

First off, major congrats and thanks for open-sourcing this as it's something I'm very interested in embedding in our studio. That said, I was wondering if there was a way to create an ICC profile dir
