* The test is now only done when some object that uses cache has actually changed.
* The added scene->physics_settings->quick_cache_step is only an internal counter, not a user changeable value.
dupliverts. The flag mode & OB_MODE_EDIT only indicates that
this object is being edited by the user, not if the mesh is
in editmode or not, it should check for the existence of
me->edit_mesh. Also corrected two other places for this.
This commit removes the Old Track method (used to be found under Object -> Animation -> Track), with all existing instances of this being converted to Track To Constraints. In fact, while performing this removal, I found that this was supposed to have happened in version 2.27 already, but for some reason the options were left in, and this function managed to survive for a further decade.
I've left the tracking axes around still, since it seems some curve tools still use that. However, that usage should probably get faded out in future too?
Misc notes:
* Fixed compiling error with constaints from harkyman's Maintain Volume patch.
* Subversion of 2.52 now bumped up to .2
Note that users should not be doing this anyway (and to some degree, I wish that they have to learn this the hard way - i.e. a crash as was before) since it is always bound to cause troubles of various sorts.
Having said this, the old tracking code was previously crashing if this sort of setup was created since a stack overflow would happen while bouncing between each object being recursively recalculated. I've fixed this by commenting out that recursive recalculation (solving the cyclic problems for n >= 2, while n=1 should still be fine without this pre-depsgraph hack), and also removing such cyclic dependencies in the n=2 case.
(PS: Perhaps this is just a good opportunity to just remove this old feature instead ;)
This commit restores fluid sim baking functionality in 2.5, it's been on the todo for
a while, and was previously almost completely non-functional. The old
code was quite complicated and specific to the 2.4 animation system, so I've
pretty much rewritten most of it.
This includes:
* Animated variables work again - just key them in the UI. Non-animateable values
should be already set non-animateable in RNA, hopefully I got them all.
Available are: Domain Gravity / Domain Viscosity / Object loc/rot/scale /
Object initial velocity / Deforming meshes / Fluid control Attract strength /
Fluid control Attract radius / Fluid control Velocity strength /
Fluid control Velocity radius / Object Active status (checkbox next to fluid type)
The Domain time scale is still not yet implemented.
* Fluid sim now use global scene units data by default - when enabled, the
scene's global gravity value is used and when units are set (metric/imperial)
the simulation real world size is taken from the object's actual measurements.
* The baking process is now done in the background, using the nifty threaded
Jobs system. It's non-blocking and your domain object will show the simulated
fluid as it becomes available for that frame.
A nice extra thing for the future would be to improve the visualisation of the
object's state while baking, and also the jobs system/ui could do with some
touchups - currently it has to share a bit from the 'render' job, and appears as
'Render' in the header. Progress bars for jobs in the header would be great too.
- use render mesh settings rather then view settings.
- fixed bug with brush size being overwritten and allowing non mesh objects to be projected onto.
- made the paint loop less messy & minor cleanup
Used approach with creating DerivedMesh for curves whet they've got such modifiers.
Available modifiers are: array, edge split, mirror, solidify, subsurf.
from reading all places dynamic hair is used I think these changes are correct (cloth seems to share pointcache with the psys) but its not obvious.
jahka: please check this is ok.
problem is that where_is_object is being called from multiple threads
but is not thread-safe, added a note about this problem, this commit
only solves the crash. Also remove the pushdata/popdata mechanism
that was being used here, using this kind of system is bound to give
problems with threading.
transforming, due to the evaluation of the object transform without
constraints, and the driver not finding the property.
Constraints are now disabled in a way that should avoid this problem
Highlights:
* Support for Multi-Target Variables
This was the main reason for this recode. Previously, variables could only be used to give some RNA property used as an input source to the driver a name. However, this meant that effects such as Rotational Difference couldn't be used in conjunction with other effects and/or settings to achieve the powerful results. Now, a variable can take several input targets, perform some interesting operations on them, and spit out a representative value based on that.
* New Variable Types
With the introduction of multi-target variables, there are now 3 types of variable that can be used: single property (i.e. the only type previously), Rotational Difference (angle between two bones), and Distance (distance between two objects or bones).
* New Driver Types
In addition to the existing 'Average', 'Sum', and 'Expression' types, there is now the additional options of 'Minimum' and 'Maximum'. These take the smallest/largest value that one of the variables evaluates to.
* Fix for Driver F-Curve colouring bug
Newly added drivers did not get automatically coloured in the Graph Editor properly. Was caused by inappropriate notifiers being used.
Notes:
* This commit breaks existing 2.5 files with drivers (in other words, they are lost forever).
* Rigify has been corrected to work with the new system. The PyAPI for accessing targets used for the variables could still be made nicer (using subclassing to directly access?), but that is left for later.
* Version patching for 2.49 files still needs to be put back in place.
This commit sets up some of the groundwork necessary to extend the animation visualisation capabilities, previously only available for bones in PoseMode, to Objects as well. Also, some of the other goals of this refactor is to make future visualisation goodies (i.e. editable paths) more feasible...
(There's really nothing to see here yet. The following log notes are really just for my own reference to keep track of things.)
Currently, the following things have been done:
* New datastructures + settings have been tidied up, ready for usage
* Added these new types into the Object and PoseBone code as necessary, with freeing/adding/copying accounted for
* File IO code for the new data, including version patching to convert the old system to the new one.
* Set up the drawing system for motionpaths based on the old armature path drawing code. Armatures still draw using the old system, since the two systems use different storage systems.
* Started setting up the motionpath 'baking' code, but the core of this still needs to be coded...
Next Steps (after some semi-urgent Durian Driver changes):
* Port the ghosting/onionskinning code over too
* Finish motionpath baking code
* RNA wrapping for the new types
* Hooking up all the new code into the operators, etc.
* Mesh data/settings can now be animated. It is not recommended that geometry be animated directly, but other settings such as autosmooth, etc. can be...
* Code cleanups for depsgraph, making sure that drivers get included for all object data types.
- Camera to 3D view didnt check for rotation order.
- Fly mode didnt check for rotation order.
added util functions.
- object_apply_mat4(ob, mat4); applies a 4x4 matrix to an objects loc,scale,rot (accounting for rotation modes)
- object_mat3_to_rot(ob, mat3, use_compat); apply a 3x3 matrix to the objects rotation, option to use a euler compatible with the existing euler.
Currently access by selecting a marking and binding with the active camera from the view menu.
Note:
after long discussion we decieded there is no nice way to do this.. animate pointers? animate multiple camera visibility?, use sequencer? use NLA?.... have a kind of event system (like framechange scriptlinks)... etc
so this is ifdef'd with DURIAN_CAMERA_SWITCH
- Offset parameter of the path constraint has no effect on the animation
- Path animation was being repeated multiple times even though it was not supposed to
This is still a bit dodgy, the issue of accessing scene data from nodes needs to be solved better, but this at least fixes it up to previous capabilities, and prevents writing any data to scene/objects either.
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:

and some docs here:

* Increased the number of Armature and Bone Layers from 16 to 32. Please note that older versions of Blender may not correctly resolve the layers that bones are on when loading new files.
* Newly added objects are now made by default to allow locking of 4-component rotations using 4 separate locks (i.e. one by component) instead of requiring the obscure 'W' toggle (renamed '4L' now) to be enabled first. The objects in the default scene need modifying manually though.
- 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.
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()
