Credits go to Gernot Ziegler, who originally coded EXR support, and to Austin Benesh for bringing it further. Kent Mein provided a lot of code for integrating float buffers in Blender imbuf and ImBuf API cleanup, and provided Make and Scons and static linking. At this moment; the EXR libraries are a *dependency*, so you cannot get the Orange branch compiled without having OpenEXR installed. Get the (precompiled or sources) stuff from www.openexr.com. Current default is that the headers and lib resides in /user/local/ Several changes/additions/fixes were added: - EXR code only supported 'half' format (16 bits per channel). I've added float writing, but for reading it I need tomorrow. :) - Quite some clumsy copying of data happened in EXR code. - cleaned up the api calls already a bit, preparing for more advanced support - Zbuffers were saved 16 bits, now 32 bits - automatic adding of .exr extensions went wrong Imbuf: - added proper imbuf->flags and imbuf->mall support for float buffers, it was created for *each* imbuf. :) - found bugs for float buffers in scaling and flipping. Code there will need more checks still - imbuf also needs to be verified to behave properly when no 32 bits rect exists (for saving for example) TODO: - support internal float images for textures, backbuf, AO probes, and display in Image window Hope this commit won't screwup syncing with bf-blender... :/
