[Soc-2016-dev] Weekly Report #02, Cycles Images

[Sergey Sharybin]

Hi,

Surely having native support of half-float OpenEXR is nice (so yo don't
upscale the storage before downscaling it), but you should in fact be able
to put any texture to a half-float storage.

Answering your question: as far as i concerned, half-float on CUDA is a
storage format which you read as full-float in the kernel.
