I've been reviewing iv as a possible render viewer for the Maya-to-Arnold translator. I came up a this list of requirements for a production-ready render viewer viewer:
[x] pan/zoom [x] handles float data [x] interactively apply exposure/gamma corrections [ ] displays multiple AOVs [ ] streams multiple AOVs [ ] provides a catalog of previous renders [x] performs A/B comparisons (basic toggle) [x] pixel sampler [?] interactively apply LUTs (via OCIO?) the two main requirements that are missing are socket streaming (which I already emailed about and will be looking into) and display of layers for extended formats like openEXR. this will also become important if we intend to stream many AOVs to iv at once. so, from my totally outside perspective, an awesome GSoC project might be multi-layer support in iv ;) -chad
