An OpenEXR Layout for Spectral Images

Alban Fichet, Romain Pacanowski, Alexander Wilkie July 2021 Journal of Computer Graphics Techniques (JCGT) Abstract We propose a standardised layout to organise spectral data stored in OpenEXR images. We motivate why we chose the OpenEXR format as basis for our …
