Story time: Once upon a time, in the green valley of fileselect, BLI_end_threads would get called on an empty threadbase, depending on the result of a previous call to readdir(). The function would then gladly decrement thread_level to -1 which would cause all kinds of fun havoc. THE END.
Made sure thread_level is only incremented and decremented when needed. The caller should never have to make sure of that, especially since it already lets you call with a null threadbase.
Please report any further hang (and how to reproduce, if possible).
* Added a 'rotOrder' parameter for constraint evaluation objects and constraint targets, which describes the rotation mode used for the matrices there.
Todos:
* Constraint targets default to using XYZ only for now. This will need be be addressed eventually.
* Copy Rotation constraint currently cannot use the new rotation order code for the target matrix. What's surprising is that even though it's just using XYZ as the old code did, it doesn't work, and yet everything else works nicely. Silly constraint! (it is almost impossible to improve this constraint further without breaking a rig out there)
* All tools where rotation order matters for armature bones have now been adjusted to use the new code
* Transform now uses the new code for bones too. However, there are some jumping issues here that I'm not too sure how to solve yet. Help fixing this is welcome.
This commit is the start of an implementation of (euler) rotation orders for Bones (later to be extended to Objects too).
Technical details and references can be found at:
http://wiki.blender.org/index.php/User:Aligorith/EulerRotationOrder
In short, I've added a new set of Euler conversion functions (EulO... and ...EulO), coexisting with the old functions for now, which can handle different rotation orders.
Changes have only been made to the basic evaluation code. However, the following places will still need modifications:
* Transform code - needs to be made to use functions which take rotation order into account instead of using XYZ only
* Rotation constraints - same story
* Other rotation editing tools for armatures also need a check up, since there might have been some missing code when I ported eulers earlier
Also, made the Outliner's horizontal scrollbar work better for keymaps view. It's still using an approximation of the width, but at least you can scroll now.
* cache for low res (deactivating high res for now)
* new way of view3d rendering of smoke (no longer 3 axes) -using 3dtexture now (introduced into gpu/intern)
* introducing LZO and LZMA libs into extern (makefiles missing for now)
* reducing memory usage after simulating for the frame ended (freeing temporary buffers)
* splitting smoke into 2 modifier for the cache-sake (it cannot handle more than 1 cache on the same modifier-index)
* no color on gui anymore
* fixing non-power-of-2 resolutions (hopefully)
* fixing select-deselect of domain drawing bug
* fixing drawobject.c coding style (making Ton happy) ;-)
HINT #1: If scons doesn't work -> cmakefiles are up-to-date, couldn't test scons (but i tried to mantain them, too)
CODERS HINT #1: we really need a way to disable adding all modifiers through "Add Modifiers" dropdown!
WARNING #1: before applying this commit, deactivate your SMOKE DOMAIN in your old files and save them then. You can open them then savely after that.
WARNING #2: File and cache format of smoke can be changed, this is not final!
Implementation Note:
* Moved the scene copy/unlink code back into blenkernel, with
the exception of the copy single user stuff which is still in
object_edit.c.
* Uses SCREENDELETE notifier like SCREENBROWSE, seems only clean
way to do this now.
- CMake, use FIND_PACKAGE(Freetype) for unix/linux
- Only link with libdl.so on linux
- use statvfs rather then statfs for netbsd (size of statfs wasnt available)
- add x11 include path with ghost, glu.
Integration is still very rough around the edges and WIP, but it works, and can render smoke (using new Smoke format in Voxel Data texture) --> http://vimeo.com/6030983
More to come, but this makes things much easier to work on for me :)
Not working:
a) rendering (since volumterics branch is not merged yet)
b) moving collision objects of any kind
c) saving of collision objects (because that's what I am working on)
d) pointcache
e) A bunch of other things I already know of
So please do not report any bugs on this one yet :-)
Bugfix: revert to previous behaviour of BLI_rename, is used for safe blendfile saving.
Added guard in file browser though to prevent user from invoking this.
* Side panels now use list widgets.
* Enabled theme colors for side panel.
* Add button in bookmarks panel.
* Operator panel title now uses operator name.
* For unix, added / to system, and home and desktop to bookmarks.
* For opening fileselect with filter, cleaned up the code a bit,
adding WM_operator_properties_filesel instead of duplicating code.
* Also added filter for all operators calling fileselect, only image
and file open did it before.
* Hide . files by default, and also hide files ending with ~.
* Added back .. (but not .) in the file list, I really missed this.
* File highlight now only happens when you're actually over a file,
instead staying after you move the mouse away.
* Fix some redraw/refresh issues.
* operator for create new directory activated (IKEY)
* operator for rename (works on files and directories so far) (CTRL+LMB)
Note: fail to rename is rather quiet, no message popup, just doesn't rename if it can't.
So far checked that (On Windows Vista) rename fails on system directories, which I think acceptable.
Note: I removed the code that (silently) deletes file if I rename file to an existing one. Considered harmful :)
Bugfixes:
* crash when loading file that has filebrowser open
* file size over 2GB/4GB? shows negative number
Other:
* tried to improve drawing speed a bit by only drawing the files actually shown and improving refresh behaviour a bit.
Note: Solution I found so far is to use the non-standard _stat64, as far as I could see, WIN64 should work without that patch (Genscher, please check and if needed you can enable this too by removing the !defined(WIN64) )
This probably needs to be fixed in at least one other place (BLI_filesize), will look into this once this fix proves stable enough)
Various fixes for painting, sculpting and particle edit, still
much to be done...
* Move RNA paint and sculpt structs into rna_sculpt_paint.c,
* Added Particle Edit RNA.
* Some tweaks to existing Paint RNA.
* Put texture paint and particle edit object in context.
* Fix some errors in the brush layout, properly doing None
checks, fixing some wrong property identifiers.
* Added tool enum for texture paint and particle edit in panels.
* Allow editing brush textures in the texture buttons, still with
a stupid toggle, ideas for how to make the connection better are
welcome.
* Fix crash entering particle mode, and particles not showing.
Janne, please check the changes I made in psys_cache_paths,
I'm not confident they are correct.
* Fix some warnings
* Windows fixes for texture filter & bump patches, thanks
Jean-Michel Soler for noting.
* Added sqrtf/sinf/fabsf/... fallback #ifdefs in BLI_arithb.h,
those should be safe to use now. Replacing the double for the
float version throughout the code can be done once, but would
need proper testing.
Patch by Alfredo de Greef. Considerably improves the quality of bump
mapping, and texture filtering for displacement and warp too. Mainly
this is achieved by getting the texture derivatives just right in
various cases, many thanks to Alfredo for figuring this one out, works
great.
This is enabled by default now, but disabled still for existing
textures to preserve backwards compatibility. Can be enabled with
the "New Bump" option in the material texture slot in the outliner.
Also, I made the range for the normal factor a bit smaller since this
gives stronger effects, but note that you can still type in larger
values than the slider allows.
Too many new features to list! But here are the biggies:
- Boids can move on air and/or land, or climb a goal object.
- Proper interaction with collision objects.
* Closest collision object in negative z direction is considered as ground.
* Other collision objects are obstacles and boids collide with them.
- Boid behavior rules are now added to a dynamic list.
* Many new rules and many still not implemented.
* Different rule evaluation modes (fuzzy, random, average).
- Only particle systems defined by per system "boid relations" are considered for simulation of that system.
* This is in addition to the boids own system of course.
* Relations define other systems as "neutral", "friend" or "enemy".
- All effectors now effect boid physics, not boid brains.
* This allows forcing boids somewhere.
* Exception to this is new "boid" effector, which defines boid predators (positive strength) and goals (negative strength).
Known issue:
- Boid health isn't yet stored in pointcache so simulations with "fight" rule are not be read from cache properly.
- Object/Group visualization object's animation is not played in "particle time". This is definately the wanted behavior, but isn't possible with the current state of dupliobject code.
Other new features:
- Particle systems can now be named separately from particle settings.
* Default name for particle settings is now "ParticleSettings" instead of "PSys"
- Per particle system list of particle effector weights.
* Enables different effection strengths for particles from different particle systems with without messing around with effector group setting.
Other code changes:
- KDTree now supports range search as it's needed for new boids.
- "Keyed particle targets" renamed as general "particle targets", as they're needed for boids too. (this might break some files saved with new keyed particles)
Bug fixes:
- Object & group visualizations didn't work.
- Interpolating pointcache didn't do rotation.
Constraints:
* Adding constraints with targets should now work.
-- (When no target is provided, the code to create a new target is not yet in place again yet)
* Constraints can be added in Object and PoseModes again using the Ctrl-Shift-C hotkey.
* All constraints can now be cleared from the active Object or selected Bones using the Ctrl-Alt-C hotkey.
* Added warnings when adding constraints invalid for the current context, and removed the old add_constraint() function.
* Buttons window updates correctly after adding keyframes now
Keyframes Drawing:
* Removed un-necessary extra function-call for RB-Tree implementation, by inlining a special one-off case.
* Keyframe diamonds which are not within the viewable area are now not drawn (but filtering will still need to find them).
- BLI_add_slash returns the new string length.
- BLI_where_am_i() would often have /./ in the path (not incorrect but annoying, got into python exceptions)
- release/ui/space_image.py, py error referencing invalid keyword args.
Keyframes are now prepared for drawing by being added to a binary-tree structure instead of using insertion-sort on a Double-Linked List. This gives rather significant improvements on a few bad cases (*).
I've implemented a basic Red-Black Tree whose nodes/data-structures can also be used as a simple Double-Linked List (ListBase) for this purpose. The implementation of this tree currently does not have support for removing individual nodes, since such capabilities aren't needed yet.
Stats (using keyframes from an imported .bvh animation file):
* When only the keyframes are drawn (i.e. long keyframes are not identified), the time needed to draw the DopeSheet region 10 times went down from 4000ms to about 300ms.
* When long keyframes are considered as well, the same test has gone from 6000ms to 3000ms. There is still a bottleneck there that I haven't been able to remove yet (an attempt at this made the runtimes go through the roof - 32000 ms for the test done here).
Assorted Notes:
* Added missing headers for some files
* Fixed profiling flags for mingw. There was an extra space which prevented the sound-code from compiling.
- 1st stage: Linear Workflow
This implements automatic linear workflow in Blender's renderer. With the
new Colour Management option on in the Render buttons, all inputs to the
renderer and compositor are converted to linear colour space before
rendering, and gamma corrected afterwards. In essence, this makes all
manual gamma correction with nodes, etc unnecessary, since it's done
automatically through the pipeline.
It's all explained much better in the notes/doc here, so please have a look:
http://wiki.blender.org/index.php/Dev:Source/Blender/Architecture/Colour_Management
And an example of the sort of difference it makes:
http://mke3.net/blender/devel/rendering/b25_colormanagement_test01.jpg
This also enables Colour Management in the default B.blend, and changes the
default lamp falloff to inverse square, which is more correct, and much
easier to use now it's all gamma corrected properly.
Next step is to look into profiles/soft proofing for the compositor.
Thanks to brecht for reviewing and fixing some oversights!
* Objects now support up to 32767 material slots. It's easy to
increase this further, but I prefer not to increase the memory
usage of mesh faces, it seems unlikely that someone would
create 32767 distinct materials?
* Forward compatibility: the only thing you can potentially lose
reading a 2.5 file in 2.4 is object linking (instead of default
data), though usually that will go fine too. Reading files with
> 32 material slots in 2.4 can start giving issues.
* The ob->colbits variable is deprecated by the array ob->matbits
but I didn't remove the ob->colbits updates in very few places
it is set.
* I hope I changed all the relevant things, various places just
hardcoded the number 16 instead of using the MAXMAT define.
* Join Objects operator back. This is using the version from the
animsys2 branch coded by Joshua, which means it now supports
joining of shape keys.
* Fix for crash reading file saved during render.
* bugfix: parent on linux didn't account for first slash
* added some BLI_cleanup_dir to prevent weird directory names
* revert to old directory if user types bogus text.
* bugfix: don't allow parent dir to go beyond root
* bugfix: only attempt to change directory if it exists
New (WIP) feature: autocomplete for directory
* works on TAB
* so far only one level (in current directory)
Monthly cleaning round to make it compile warning free.
Mostly it was const stuff (strings, Context), but also
a couple useful fixes, like wrong use of temp pointers.
Only Mathutils callback struct I left alone... design issue.
* show only name of the last directory for the bookmark
* small fix of projectfile: header BLI_fileops.h was moved
Note: full path should appear in tool tip later, also for renaming bookmarks later on.
Mostly harmless ones, except for one about "gzopen64" being
undeclared. This needs some defines in BLI_storage.h to be set
before <unistd.h> is included. Might fix a crash in compressed
file reading, though I'm not sure since it's hard to repeat
the crash consistently.
* removed radiosity render code, DNA and RNA (left in radio render pass options), we'll get GI to replace this probably, better allow baking to vertex colors for people who used this.
* removed deprecated solid physics library, sumo integrations and qhull, a dependency
* removed ODE, was no longer being build or supported
* remove BEOS and AMIGA defines and references in Makefiles.
* Added support for additional file types in the voxel data texture. I added
support for 8 bit raw files, but most notably for image sequences.
Image sequences generate the voxel grid by stacking layers of image slices on top
of each other to generate the voxels in the Z axis - the number of slices in the
sequence is the resolution of the voxel grid's Z axis.
i.e. http://mke3.net/blender/devel/rendering/volumetrics/skull_layers.jpg
The image sequence option is particularly useful for loading medical data into
Blender. 3d medical data such as MRIs or CT scans are often stored as DICOM
format image sequences. It's not in Blender's scope to support the DICOM format,
but there are plenty of utilities such as ImageMagick, Photoshop or OsiriX that
can easily convert DICOM files to formats that Blender supports, such as PNG or JPEG.
Here are some example renderings using these file formats to load medical data:
http://vimeo.com/5242961http://vimeo.com/5242989http://vimeo.com/5243228
Currently the 8 bit raw and image sequence formats only support the 'still'
rendering feature.
* Changed the default texture placement to be centred around 0.5,0.5,0.5, rather
than within the 0.0,1.0 cube. This is more consistent with image textures, and it
also means you can easily add a voxel data texture to a default cube without
having to mess around with mapping.
* Added some more extrapolation modes such as Repeat and Extend rather than just clipping
http://mke3.net/blender/devel/rendering/volumetrics/bradybunch.jpg
* Changed the voxel data storage to use MEM_Mapalloc (memory mapped disk cache)
rather than storing in ram, to help cut down memory usage.
* Refactored and cleaned up the code a lot. Now the access and interpolation code
is separated into a separate voxel library inside blenlib. This is now properly
shared between voxel data texture and light cache (previously there was some
duplicated code).
* Made volume light cache support non-cubic voxel grids. Now the resolution
specified in the material properties is used for the longest edge of the volume
object's bounding box, and the shorter edges are proportional (similar to how
resolution is calculated for fluid sim domains).
This is *much* more memory efficient for squashed volume regions like clouds
layer bounding boxes, allowing you to raise the resolution considerably while
still keeping memory usage acceptable.
* Missing changes to release/windows/installer
* Sequencer fixes in source/blender/src/seqaudio.c dont apply to 2.5
* brechts fix for #18855 r20763 wasnt merged, does this apply to 2.5?
