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.
Adds a new set of bones to rig types which are to be used for weight paint vgroups, in some these have some more segments to account for twist. also use Aligoriths new copy transform constraint.
* option to roll the delta of the arm rig.
* fix to copy metarig type
* renamed EditBone.align() --> EditBone.align_roll()
* Added EditBone.align_orientation(other)
* Added bone.vector: same as (bone.tail - bone.head)
On ubuntu/debian install these tools...
sudo apt-get install pylint pyflakes python-setuptools python-pip
sudo pip install pep8
then run from blenders source dir...
python release/test/pep8.py
This searches for the comments "# <pep8 compliant>" and "# <pep8-80 compliant>", running the checking tools on these scripts only.
* some minor pep8 corrections too.
* optional default blend argument, use for better leg & arm defaults
* way to define arbitrary options for bones that can then be passed to the generator function, only used to set elbow target parent at the moment.
- use reverse order for palm fingers (pointer first)
- allow copying bone class instances to exclude some bones
- doc generation had a python error (incedently updated online docs linked from the splash)
- Neck example didnt account for some possible problems when linking to the body
- foot IK were referencing the wrong bones
- updated some example rigs
- graph constraint arrow direction was incorrect
- use python malloc's in bpy_array.c
- automatically blending bone locations is disabled if the target bone has locked location
- neck had incorrect roll
also avoids hitting the 255 string limit if you want to add 100's of values. eg.
>>> b05/max(0.001, [globals().update({"LOCALS":locals(), "ADD":float.__add__, "reduce":__import__("functools").reduce}), 0.0][1], max((, [LOCALS["b%.2d" % (i+1)] for i in range(5)])))
Since this more simple expression reaches the limit fairly quick...
>>> b05/max(0.001,b01+b02+b03+b04+b05)
- updated delta not to remove a bone
- spine and neck rigs interpolation bones are now axis aligned to the control bone
- palm tag is expected on the pointer finger rather then the wrist
- operate on bone children first working up the chain (not essential but more pradictable)
original bone names cant be changed anymore but this means the bones can be re-parented without confusing scripts that run after the rig is modified.
support for defining a bone to have multiple types and automatically blending between 2 generated rigs
