My name is Joshua Jackson. I'm writing a custom configuration with ocio and have a quick question: Can I apply Matrix Transforms in a different order than RGB x MTX x etc... ? For Chromatic Adaptation Transforms, it is neccessary to apply a matrix in a different order to the given RGB/XYZ/etc. ( MTX x RGB x etc.) Thank you so much for your time!

Looking at the code OCIO implements Matrix*RGBA (column vector). In matrix operations RGBA*transpose(matrix) = matrix*RGBA. If you feel you are getting the wrong multiplication order then try using the transpose of the matrix. On Wednesday, June 11, 2014 6:40:33 AM UTC-7, Joshua Jackson wrote:
