Also fixes:
* Weight paint subsurf drawing.
* Missing pointer endian conversion in paint brushes.
* Use of unitialized variable in screen version patch.
* Multires modifier without mdisps layer crash.
* Sound strips now respect metastrips for muting. That means they
are muted if the metastrip is muted, and don't play when located
outside of the current metastrip.
* Operators now use notifiers instead of redraw tagging, added a
separate notifier for selection as well, but that is not used to
do less redraws yet.
* Make partial update work again for faster editing.
* Draw parents over children again, nicer for editing.
* Fix crash with remove tools & showing child particles.
* Fix children not disappearing always when setting to None.
* Fix wrong normal for last point in child path.
* Fix a python error in the hair dynamics panel.
After testing and feedback, I've decided to slightly modify the way color
management works internally. While the previous method worked well for
rendering, was a smaller transition and had some advantages over this
new method, it was a bit more ambiguous, and was making things difficult
for other areas such as compositing.
This implementation now considers all color data (with only a couple of
exceptions such as brush colors) to be stored in linear RGB color space,
rather than sRGB as previously. This brings it in line with Nuke, which also
operates this way, quite successfully. Color swatches, pickers, color ramp
display are now gamma corrected to display gamma so you can see what
you're doing, but the numbers themselves are considered linear. This
makes understanding blending modes more clear (a 0.5 value on overlay
will not change the result now) as well as making color swatches act more
predictably in the compositor, however bringing over color values from
applications like photoshop or gimp, that operate in a gamma space,
will give identical results.
This commit will convert over existing files saved by earlier 2.5 versions to
work generally the same, though there may be some slight differences with
things like textures. Now that we're set on changing other areas of shading,
this won't be too disruptive overall.
I've made a diagram explaining the pipeline here:
http://mke3.net/blender/devel/2.5/25_linear_workflow_pipeline.png
and some docs here:
http://www.blender.org/development/release-logs/blender-250/color-management/
- Drivers on added to the 'armature' datablock (i.e. keyframing some settings for a "Bone" as opposed to "PoseBone") now evaluate correctly. Added proper recalcs for this case too.
- Also fixed some memory leaks and loading problems I encountered with the test file provided. After having problems loading the test file, I ended up reproducing and finding the error.
* This is experimental, the file format may change still!
* Helps reduce memory usage, keeps .blend files smaller, and makes
saving quicker when not editing multires.
* This is implemented at the customdata level, currently only the
multires displacements can be stored externally.
ToDo
* Better integration with object duplication/removal/..
* Memory is not yet freed when exiting sculpt mode.
* Loading only lower levels is not supported yet.
* Displacement coordinates are now stored differently, as a grid per
face corner. This means there is duplication of coordinates, especially
at low subdivision levels, but the simpler implementation justifies it
I think.
* ToDo: conversion of existing multires files (2.4x or 2.5x), loading them
may even crash now.
* Editmode preservation/interpolation code also has not been updated yet.
* Multires now works on the CCGDerivedMesh grids instead of CDDerivedMesh,
which should be more memory efficient.
* There are still bad memory peaks (if you're using 32bit) when subdividing
or propagating displacements. Though at least there should be no huge
memory blocks allocated, which windows is now to have trouble with.
* Still found some weird spike artifacts at lower multires levels, some also
happening before this commit. Perhaps computation of tangents needs to be
tweaked more.
* Multires modifier now has viewport, sculpt and render levels. Also the
levels have been made consistent with subsurf, previously the same level
of subdivision was one less for multires.
* Both multires and subsurf modifier now can have their subdivision level
set to 0 for no subdivision.
To insert keys, use I key while hovering over the button for now, rmb clicking on the property to insert a key doesn't work (general bug for all regions except property editor - will investigate).
Doesn't convert over from old fac0 ipos on opening old files though for the time being.
* Made sequence strip names unique while I was at it, to allow strip properties to be animated properly.
* structural can be set to 0
* pre-roll now available through GUI and works like following:
a) Pre rolled frames are NOT cached
b) reset cache + cloth on pre roll setting change
Added a group example
C = bpy.context
ob = C.active_object
bpy.data.groups[0].objects.add(ob)
- add_to_group and rem_from_group now take optional scene and base flags and deal with updating the object & base flags
- operators that add objects to groups were setting ob->recalc= OB_RECALC_OB; looks like its not needed.
- previously add() ignored python args, now add and remove are called like any other FunctionRNA from python.
- made the pyrna api use tp_getset's for collestions active/add()/remove()
Now the rna path to nodes happens via the node name, which is ensured to be unique via RNA.
As part of this, the node->username string has been removed, upon renaming the node itself it takes care of making sure it's unique (like bones, constraints, etc). There's currently no interactive rename tool, but you can do it via the datablocks editor.
- plus a few notifier tweaks, using the newer NC_NODE notifier to refresh graph editor etc.
This commit restores Grease Pencil functionality for the Nodes Editor. Grease Pencil data is now stored at the NodeTree level, which means that annotations remain with the NodeTree they were made for.
Possible TODO's:
* In future, it may be worth investigating attaching Grease Pencil data to individual nodes, to allow annotations to stay attached to nodes as they are moved
* Include the settings for the 'active node' in a panel in the new NKEY region where the Grease Pencil buttons appear.
* Convert all code to use new functions.
* Branch maintainers may want to skip this commit, and run this
conversion script instead, if they use a lot of math functions
in new code:
http://www.pasteall.org/9052/python
Still a few quirks, including redraw issues on multilayer image input nodes, but it's pretty much there.
Would also be good to wrap the input/output sockets, too, will check on it.
This fixes bug [#19740] INPUT NODE: Cannot load images / motion pictures
* Fixed the handling of the 'draw_active' flag for drawing of armatures. This is now cleared from bones in old files (so one bone always got represented as active in the viewport even when others were selected), and the flag is correctly set temporarily when drawing the bones (only one place had been done).
* Fixed typo with SplineIK that was making the root bone of the bone chains always be ignored. Similar functionality can come back at some point, but in a more useful form.
* Shortened the UI names for the F-Curve colouring modes to increase readability. The old ones were too long to be able to distinguish between entries in the UI.
- rna vars arm.bones.active & rna.edit_bones.active
- needed special undo support.
- readfile.c loads.
- duplicate and copy_armature support.
- keep the draw flag, renamed to BONE_DRAW_ACTIVE, only use for openGL drawing.
Note: it may be better to allow active/unselected as with objects.
Non-ID pointers in DNA can only point to data from own ID block, so
now instead it uses an index into the particle system list, but still
exposed as a pointer through RNA.
* Fixed crash when reloading a file with Spline IK and/or Damped Track constraints. The targets for these constraints weren't getting relinked.
* Fixed problems with removing Spline IK making some bones unable to be manipulated.
* Jotted down some comments in the Spline IK code noting places where additional tweaks will be added.
At last, this commit introduces the Spline IK Constraint to Blender. Spline IK is a constraint that makes n bones follow the shape of a specified curve.
Simply add a chain of bones, add a curve, add a Spline IK Constraint to the tip bone and set the number of bones in the chain to make it work. Or, try the following test file:
http://download.blender.org/ftp/incoming/250_splineik_spine01.blend
Screenshots of this in action (as proof):
http://download.blender.org/ftp/incoming/b250_splineik_001_before.pnghttp://download.blender.org/ftp/incoming/b250_splineik_001_after.png
I've implemented this in a similar way to how standard IK solvers are done. However, this code is currently not an IK plugin, since I imagine that it would be useful to be able to combine the 2 types of IK. This can be easily changed though :)
Finally, a few notes on what to expect still:
* Constraint blending currently doesn't affect this. Getting that to work correctly will take a bit more work still.
* Options for not affecting the root joint (to make it easier to attach the chain to a stump or whatever), and non-uniform scaling options have yet to be added. I've marked the places where they can be added though
* Control over the twisting of the chain still needs investigation.
Have fun!
* AutoKeying was broken after the fix to get automerge working again in 3D view. The 3D-View check was swallowing the processing before autokeying could be done. Separated these out again.
* The error print when some external data couldn't be found for objects was missing a newline.
Internal change to not apply the shape keys to the Mesh vertex coordinates,
but rather use it as part of the derivedmesh/displist evaluation. This only
has one practical advantage right now, which is that you can now make a
linked duplicate and pin it's shape key to a different shape than the first
object.
Further, this makes shape keys correctly fit into the modifier stack design,
which will help implement some other features later. Also it means the mesh
vertex coordinates are now really the orco's.
that completely:
* quit.blend is saved from the undo file, which did not save out library
ID_LI and ID_ID blocks, for quick undo keeping the library datablocks.
However this means library links are lost on reading the quit.blend, so
now instead of not writing them, they are not read on undo.
* Libraries were not not using the right path yet always.
Note the screen setup is still not recovered from the quit.blend if no
auto save happened yet, but that is not important enough to spend time on
now.
Auto save is now working again in 2.5. It will also remember now what
the location of the original file was when recovering it, so that
library links still work and saving the restored file does not save to
the temp directory. There is also a new Recover Auto Save operator
which will open the filebrowser in the temp directory and show the
auto saved .blends.
Implemenation Notes:
* Timer storage was moved from window to windowmanager, so we can have
windowmanager level timers too now, doesn't make sense to have
autosave timer attached to a particular window.
* FileGlobal now has a filename field storing where the file was saved.
Note that this is only used when loading a file through the recover
operators, regular file read doesn't use it, so copying the quit.blend
manually over the original file will still work as expected.
* Jobs timer no longer uses operator now, this seems more like an
internal thing, changing keymaps should not make it possible to break
the jobs manager.
* Autosave is postponed by 10 seconds when a modal operator is running,
e.g. transform or file browsing.
* Moved setting G.sce in setup_app_data before depsgraph updates, these
can use the filename for pointcaches.
Since the deep shadow buffer summer of code project is not actively under
development anymore, I decided to build my own DSM implementation from
scratch, based on reusing as much existing shadow buffer code as possible.
It's not very advanced, but implements the basic algorithm. Just enough so
we can do shading tests with it, optimizations and other improvements can
be done later.
Supported:
* Classical shadow buffer options: filter, soft, bias, ..
* Multiple sample buffers, merged into one.
* Halfway trick to support lower bias.
* Compression with user defined threshold.
* Non-textured alpha transparency, using Casting Alpha value.
* Strand render.
Not Supported:
* Tiling disk cache, so can use a lot of memory.
* Per part rendering for lower memory usage during creation.
* Colored shadow.
* Textured color/alpha shadow.
* Mipmaps for faster filtering.
* Volume shadows.
Usage Hints:
* Use sample buffers + smaller size rather than large size.
* For example 512 size x 9 sample buffers instead of 2048 x 1.
* Compression threshold 0.05 works, but is on the conservative side.
* Fix crash trying to enter particle mode when the particle modifier
is disabled in the stack.
* Fix redraw being very slow due to the draw function causing the
object to be recalculated on each redraw (through PE_draw_object).
* Removed the system where PE_get_current would automatically create
the particle edit, this would run from poll() functions, which gave
all kinds of issues, now it only creates the data on enter/exit
and switching active particle system.
