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... :/
To enable dynamic tiff support.
I had to fix some of the logic in the fileselect box for icons,
I also expanded the patch to look in various default locations for
a dynamic libtiff.so/libtiff.dll
and look at the env variable BF_TIFF_LIB if it can't find it automatically.
If unable to load the library it prints a message about setting BF_TIFF_LIB
to the console.
I haven't been able to test it on a lot of platforms but hopefully it
will just work ;) I added the files to scons but have not had a chance to
test that as well.

This adds Radiance HDR image file support. So now at least we can save
the 'fbuf' (4x32 bits float colors) in Blender.
It doesn't change anything for internal support in imbuf for floa colors,
so when reading .hdr files it still converts it to 32 bits RGBA.
As an extra I've added that saving images with F3 now also adds the
optional extension, when the F10 "Extensions" option is set.
One important note; I don't know the proper license for the code, it was
provided without... will await feedback from Alfredo about it. For now
I've added the standard Blender GPL header.
removed leftovers from Freeimage/Imagemagick experiments
and removed stuff from a Quicktime for linux implementation.
Also removed the (win32) Fullscreen button from the UI and
disabled the corresponding commandline option. The code is
still present to reenable the option whenever the ATI issues
get solved.
This code allows you to load Quicktime images and movies as textures
and render animations to Quicktime movies.
Note that the selected output codec is *not* saved in the blendfile.
To enable Quicktime functionality you need the SDK from Apple:
OSX: ftp://ftp.apple.com/developer/Development_Kits/QT6SDK_Mac.hqx
Win: ftp://ftp.apple.com/developer/Development_Kits/QT6SDK_Win.hqx
Add the \QTDevWin\CIncludes and \QTDevWin\Libraries directories
from this SDK to your build environment.
Enable the WITH_QUICKTIME compile flag in the following directories:
bf\blender\source\blender\imbuf
bf\blender\source\blender\src
bf\blender\source\blender\render
bf\blender\source\creator
