It seems like the OCIOLookTransform node mentioned on this page: http://opencolorio.org/userguide/looks.html Is missing from the OCIO bundled with Nuke 7.0v4. Has the LookTransform node been deprecate

It looks like Nuke 7.0v6 ships with the OCIOLookTransform node, though it's not exposed in the menus by default. Quoting the release notes... BUG ID 24785 - OCIOLookTransform was missing from the Othe

Hi, In my application, images are split into their separate channels, and operations are performed per channel. I have individual float arrays for each channel (obtained via openimageio), and I would

If your image is packed separately per channel (ex: RRRRRRR... GGGGG... BBBB.... ), the Planar ImageDesc is probably what you're looking for. Give that a try? PlanarImageDesc(float * rData, float * gD

Hi All, I am looking to build the core lib with the -D OCIO_NAMESPACE=foo option. Whilst this builds just fine, I see that the SONAME is unchanged with the above. So, how do you resolve ambiguities he

Not sure exactly what you are asking, but.. The P3 to XYZ transform is typically done as a colour matrix and gamma adjustment, which could also be baked into a 3D LUT There is a description of the spi

Hi, I'm trying to convert the S-Log2/S-gamut 10-bit 422 XAVC footage coming out of my Sony F55 camera to a sequence of Linear ACES RGB OpenEXR files. I would like to validate the assumptions I make th

Are you running make with parallel jobs enabled (e.g. "make -j 4")? If so, the real error is likely buried further back in the build output.

Hi, The convert utility seems to only convert a given image from one color space to another. How can I convert the LUT itself? Specifically, I am trying to convert Iridas .CUBE to Lustre .3dl Plz help

For those of you attending SIGGRAPH 2013 in Anaheim next week, we will be once again holding an event for developers and users of VFX-specific open source projects. It's a great chance to meet in pers

Hi guys, I noticed there is an issue with getting the active Views list when it has been overridden in the environment using OCIO_ACTIVE_VIEWS. I've attached a patch that will fix this. Also I noticed

Hello ! I wrote a python script to plot 1D and 3D LUTs. It uses pyOpenColorIO to read and process LUTs and matplotlib to plot them. For the moment, I have to specify manually if the LUT is 1D or 3D to

Folks, As you may have noticed, ASC-CDL was selected for Sci-Tech consideration this year under the category of "Digital workflow specifications for managing color". http://www.oscars.org/press/pressr

Not directly. The issue that makes this complex is that some lut files (such as csp) can contain both 1D and 3D luts together. So the distinction between what should be considered 1-D, vs 3-D isn't al

I've resumed looking into integrating OCIO into RV, now that RV's Python support is non-beta \o/ (I should qualify that with "thirdparty OCIO integration, as my affiliation with Tweak is no more than

Hi! In a scenario where the LUT name consists of some known variables and an arbitrary string I would like to use something like regular expressions to match the LUT file. For example, ./001/0001/from

Hi Ben, My example where a 1D lut would be insufficient is where the source image is already in float linear, and a grading operation is to be applied in log (like saturation). Here negative values ar

Hey all, I hope I'm not spawning a duplicate discussion thread; I did some searching around, but couldn't find anything. I'm wondering if there has been any discussion about allowing multiple config f

Hi, I'm currently looking at moving our existing color pipeline tools over to OCIO, and I'm wondering if anyone can see a place for such a feature. In our current setup, some of our log to lin convers
