Now it's a bit more robust, tagging images with profiles when they're loaded,
which then get interpreted later on by conversion functions. Just Linear RGB
and sRGB profiles at the moment, same as before.
This commit fixes Martin's problem with EXRs and Multilayer images loading/
saving too dark, and it also makes the sequence editor work correctly with it too.
Also fixes:
[#19647] gamma correction with color management is reset when resetting Curve
[#19454] 2.5: Dither does not work when Color management is enabled

Was annoying to use a different editor for cmake only.
theeth says this should be ok with gsoc and merges from branches.

* bring back 'player' libtype, after investigation with ideasman.
scons/mingw works nicely, for some reason msvc fails to link still, will look further into it.
|
|
* further cleaning of 'player' stuff. Now only 3 libs are remaining, of which ideally the stubs lib will be fixed at some point, fading away into the dark history of not-so-nice code. The current blenderplayer part is still a little bit hackish, I'll see if I can find a better alternative, for now it works good enough.

Compiling openexr_api.cpp requires WITH_OPENEXR, to get the right part of the
openexr_multi.h file. Broken since r22739.

Notes:
* Game and sequencer RNA, and sequencer header are now out of date
a bit after changes in trunk.
* I didn't know how to port these bugfixes, most likely they are
not needed anymore.
* Fix "duplicate strip" always increase the user count for ipo.
* IPO pinning on sequencer strips was lost during Undo.

New priorities for most libs, at least core. This is still for Blender proper, BGE and such still to come.

with OpenEXR in the CMake system. This is a compilation fix from
Miguel A. Figueroa Villanueva for building Debug versions of Blender
using OpenEXR (thanks!).

Issues:
* GHOST/X11 had conflicting changes. Some code was added in 2.5, which was
later added in trunk also, but reverted partially, specifically revision
16683. I have left out this reversion in the 2.5 branch since I think it is
needed there.
http://projects.blender.org/plugins/scmsvn/viewcvs.php?view=rev&root=bf-blender&revision=16683
* Scons had various conflicting changes, I decided to go with trunk version
for everything except priorities and some library renaming.
* In creator.c, there were various fixes and fixes for fixes related to the -w
-W and -p options. In 2.5 -w and -W is not coded yet, and -p is done
differently. Since this is changed so much, and I don't think those fixes
would be needed in 2.5, I've left them out.
* Also in creator.c: there was code for a python bugfix where the screen was not
initialized when running with -P. The code that initializes the screen there
I had to disable, that can't work in 2.5 anymore but left it commented as a
reminder.
Further I had to disable some new function calls. using src/ and python/, as
was done already in this branch, disabled function calls:
* bpath.c: error reporting
* BME_conversions.c: editmesh conversion functions.
* SHD_dynamic: disabled almost completely, there is no python/.
* KX_PythonInit.cpp and Ketsji/ build files: Mathutils is not there, disabled.
* text.c: clipboard copy call.
* object.c: OB_SUPPORT_MATERIAL.
* DerivedMesh.c and subsurf_ccg, stipple_quarttone.
Still to be done:
* Go over files and functions that were moved to a different location but could
still use changes that were done in trunk.

Small one: changed the string attribute in multilayer exr files to be:
"2.43 and newer"
To indicate that it's about compatibility of the exr file, not the version
Blender saved it in.
|
|
|
|
|
|
For simple RGB(A) files, the channel names in openexr were supposed
to be simply "R" "G" "B" and "A" too.
Other programs like other names... like lower case, or like "ambient.r"
Tested with file from renderman.
|
|
both file formats crashed on saving images with less than 4 channels.
|
|
blocks that were previously missed; and b) greatly increase my
ohloh stats!
|
|
must be divisible by the number of parts.
- OpenEXR code also has some changes to allow writing mipmapped images,
but that is unused at the moment.

Press Rkey in compositor for reading back render results and invoke a compo.
This now correctly reads AO (skipped it sometimes) and it makes a correct
composite.
FSA todo:
- hotkey + button for reading all samples back + composite
- solve black border around image
|
|
crashing there now with FSA, if it crashes again this should give
more info.
|
|
* some lib renaming
|
|
|
|
Basically I moved -funsigned-char -fno-strict-aliasing
from individual Makefiles to nan_compile.mk defines for CFLAGS and CCFLAGS

* fix [ #6105 ] Blender crashes when opening multilayer with node in compositor
- Mem_IStream membuf was allocated on the stack, so it caused major troubles when
out of the function scope. Now allocate it on the heap and let OpenEXR deal with
freeing it.
- moved + added delete file;'s for completeness

|
- fix for 3DPlugin compile
- cleanup of bullet path
- removed PHY_ODE project from 3D plugin too, not used anymore
Now all configurations should build again, let me know of any problems!
Not been able to test if the 3DPlugin is actually working,is job for another day ;)
Also the 3DPlugin is compiled without OpenExr, this needs to be looked into once too.

OpenEXR MultiLayer: line order DECREASING_Y (openexr spec) crashes newer
openexr libs in windows... ???
Removed it, since tests reveiled the line order is still bottom-top
|
|
Y coordinate 0 in left-bottom of screen :)
Fun news: cinepaint now reads such files too:
http://www.blender.org/bf/cornelius.exr_sc1.jpg
|
|
tiles in the file, that read back fast as black. This also solves
crashes on partial written files, when trying to read them.
|
|
Without setting anything, it uses ZIP now as default, which gives the best
lossless compression and works nice fast.
|
|
for me of course :)
|

Please read:
http://www.blender3d.org/cms/Imaging.834.0.html
Or in short:
- adding MultiLayer Image support
- recoded entire Image API
- better integration of movie/sequence Images
Was a whole load of work... went down for a week to do this. So, will need
a lot of testing! Will be in irc all evening.

OpenEXR can be linked in DEBUG mode on Windows using the libraries in CVS and stub.
|
|
different platforms will follow soon. This was just tested against current CVS on MSVC 2005 with Verse, QuickTime, OpenEXR, Player all on.

probably causing the leakage issues we have exr in linux.

New option "Save Buffers", in first Output panel of renderbuttons, will not
allocate all render buffers, but instead save the rendered tiles to exr.
For each scene rendered, a single exr file then is created.
After rendering, the files get read, and only then the memory allocation is
done.
The exr files are saved in the temp dir (from user settings), and have
names derived from the filename+scene name. That way these buffers remain
relatively unique, and can be re-used later too.
Saving all render-layers and passes in a single file (as F3 command) will
be done later. Also reading back the current muli-layer exr files is not
supported yet (will read black). The purpose is that these files then can
be used as input for the Compositor.
One fun thing I added; after rendering once with this option, close
Blender, and restart it. If you have a Composite set up press 'R' on an
active RenderResult node. This will refresh the node(s) and load the exr,
so you can composite again without a re-render.

Note: it is currently disabled still... will commit the real version
soon.

passes in single file. Code is currently disabled, commit is mainly to
have a nicer method of excluding OpenEXR dependency from render module.
This should compile with disabled WITH_OPENEXR too.
Reason why EXR is great to include by default in Blender is its feature
to store unlimited layers and channels, and write this tile based. I
need the feature for saving memory; while rendering tiles, all full-size
buffers for all layers and passes are kept in memory now, which can go
into 100s of MB easily.
The code I commit now doesn't allocate these buffers while rendering, but
saves the tiles to disk. In the end is it read back. Overhead for large
renders (like 300 meg buffers) is 10-15 seconds, not bad.
Two more interesting aspects:
- Blender can save such multi-layer files in the temp directory, storing
it with .blend file name and scene name. That way, on each restart of Blender,
or on switching scenes, these buffers can be read. So you always see what was
rendered last. Also great for compositing work.
- This can also become an output image type for rendering. There's plenty of
cases where you want specific layers or passes saved to disk for later use.
Anyhoo, finishing it is another days of work, and I got more urgent stuff
now!

(NOTE: new include dependency in Render module, might need MSVC update!
It has to include the imbuf/intern/openexr/ directory in search path)
-> New Composite node: "Hue Saturation".
Works like the former 'post process' menu. There's no gamma, brightness or
multiply needed in this node, for that the Curves Node functions better.
-> Enabled Toolbox in Node editor
This now also replaces the SHIFT+A for adding nodes. The nodes are
automatically added to the menus, using the 'class' category from the
type definition.
Current classes are (compositor examples):
Inputs: RenderResult, Image
Outputs: Composite, Viewer
Color Ops: RGB Curves, Mix, Hue Saturation, AlphaOver
Vector Ops: Normal, Vector Curves, Map Value
Filters: Filter, Blur, VectorBlur
Convertors: ColorRamp, RGBtoBW, Separate RGBA, Separate HSVA, Set Alpha
Generators: RGB, Value, Time
Groups: the list of custom defined nodes
-> OpenEXR tile saving support
Created an API for for saving tile-based Images with an unlimited amount
of layers/channels. I've tested it for 'render result' now, with the idea
that this can (optionally) replace the current inserting of tiles in the
main result buffers. Especially with a lot of layers, the used memory for
these buffers can easily go into the 100s of megs.
Two other advantages:
- all 'render result' layers can be saved entirely in a single file, for
later use in compositing, also for animation output.
- on each render, per scene, a unique temp file can be stored, allowing
to re-use these temp files on starting Blender or loading files, showing
the last result of a render command.
The option is currently disabled, needs more work... but I had to commit
this because of the rest of the work I did!
-> Bug fix
The Image node didn't call an execute event when browsing another image.

+ 'scons blenderplayer' builds blender AND blenderplayer now (tested on Linux
only, but was only linking issue, so should work on other platforms too).
NOTE: I noticed some compileflags for GE specific libs that were left out -
I re-enabled them in the SConscripts, but I'm going to do a test build my-
self now, so if there are problems with them on win32, I probably already
know about them :)
|

* This commit is all of the rewrite work done on the SCons system. For
documentation see doc/blender-scons.txt and doc/blender-scons-dev.txt.
Also http://mediawiki.blender.org/index.php/BlenderDev/SconsRefactoring
contains valuable information, along with what still needs to be done.
- linux, os x and windows compile now.
- files are compiled to BF_INSTALLDIR (see config/(platform)-config.py)
- NOTE: Jean-Luc P will commit sometime during the weekend proper
appit() for OS X. For now, copy the resulting binary to an
existing .app bundle.
- features:
- cleaner structure for better maintenance
- cleaner output during compile
- better handling of build options
- general overall speed increase
- see the wiki for more info
Cygwin, FreeBSD and Solaris systems still need work. For these systems:
1) copy a config/(platform)-config.py to ie. config/cygwin-config.py
2) set the proper defaults for your platform
3) mail me at jesterking at letwory dot net with you configuration. if
you need any modifications to the system, do send a patch, too.
I'll be giving first-aid today and tomorrow, after that it'll be all
regular development work :)

Until now, the zbuffer was written straight from the internal zbuffer,
which has values that are inverse-proportional (like 1.0/z) which makes
it very hard to use it for postprocess, like zblur or other composit effects
that require Z.
Based on info from ILM, the values stored for Z in exr files is the
actual distance from a camera. I think that's about time to migrate to that
convention!
By default now, after render, the z values are converted to floats. This
saves in exr files now, but not in the Iris Z files. That latter was a
blender-only anyway, so might be not a real hassle to drop. :)
You can see the difference in the image window, but notice the range now
is linear mapped from camera clipstart to clipend.
Note; I just discover that ortho Z values need a different correction...
|
|
- images with a so-called "data window" (have negative start coordinate)
did not read correctly
- negative colors were not clamped yet in imbuf
Now there's still some compliancy issues with zbuffers... you can save
it either as unsigned int or as float, whilst blender renders zbuffer in
signed int. :)
