Correct hierarchy of terminology should be:
* Window (OS level window with borders)
* Area (top level subdivision in Blender UI), containing an
* Editor (actual UI functionality such as 3D View, Properties)
* Region (subdivision of an area, i.e. a header, a properties panel or toolbar)

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.
Rotation operator now saves axis of rotation (when not using a constraint). Better for operator redo and tweak (would use a Z axis because of matrix init)
Also fix crash in Translation operator redo and tweak (rv3d is not always available).
* Fix#20482: grab brush + size pressure sensitivity don't work
together, disabled the pressure sensitivty for that case now.
* Fix for smooth brush messing up mesh sometimes, smooth factor
is now clamped to reasonable range.
* Fix#20449: smooth brush + mirror modifier could crash.
utility functions to find the groups and scenes this object is used in.
button to set the group location from the cursor (UI is horrible but not any nice place to add?)
smarp project would fail if there were linked meshes in the scene, made ID.tag ignore the library, so you can tag linked data since its only for tools to use.
normalize the vertex normal before setting and use inline vector functions.
Better solutions could be...
- use a tool to set mirror locations (did a script for this in 2.4x), then run this if locations get messed up..
- find the closest mirror vertex, would be slower
- have a configurable threshold.
Testing a new method that hopefully will be faster to use than finicky socket
selection - now just select multiple nodes and press F - available output sockets
on the selected nodes will get automatically connected to the active node.
It works for one socket type each time, to avoid getting lots of extra connections
when you join up, but as a shortcut you can easily press F again to connect up
other socket types. For example, to connect a render layer node (with vector pass)
to a vector blur node, select the render layer then the vector blur, and press F
three times to connect up the Image, Z and Vector sockets. It now also
preferences sockets with the same name to connect up first.
There's also another option (ctrl F) which will replace existing input links, rather
than only connecting up links to available input sockets.
* Also changed socket link knife cut to a more convenient shortcut - Ctrl LMB tweak
Also: Changed 'Spread' value to be proportional to the light cache voxel grid
(i.e. 0.5 spreads half the width of the grid), so that it's independent of light
cache resolution. This means that results should be similar as you increase/
decrease resolution.
* added some new variables (mostly the same as with scons):
- USE_COCOA: use Cocoa for ghost (defaults to true)
- MACOSX_ARCHITECTURE: can be ppc, ppc64, i386, x86_64. By default this is the host architecture
(ppc for PowerPC Macs, i386 for Intel Macs). In theory this allows to cross compile blender for
a different architecture, though cross compilation only works on Intel Macs, because makesdna
and makesrna are built for the target architecture.
For a 64 bit build, set MACOSX_ARCHITECTURE to x86_64 (Intel) or ppc64 (PowerPC).
- MACOSX_MIN_VERS: minimum OS X version to run blender on (10.4 for 32 bit builds, 10.5 for 64 bit builds)
- MACOSX_DEPLOYMENT_TARGET: needed by the linker to create an Application targeted for a specific
OS version (defaults to 10.4 for 32 bit builds, 10.5 for 64 bit builds)
- MACOSX_SDK: path to a specific SDK. currently not used
- USE_QTKIT: use QTKit instead of QuickTime (defaults to true for 64 bit builds, as using QTKit
is mandatory in that case))
* use the same compiler flags as scons
* default compiler now is gcc-4.0 when building for 10.4 and gcc-4.2 when building for 10.5
* extract $(LCGDIR)/release/python_$(MACOSX_ARCHITECTURE).zip to Application bundle. This might
break building on 10.4, to fix that, rename $(LCGDIR)/release/python.zip
When compiling blender, only MACOSX_ARCHITECTURE might be of interest, as it allows doing 64 bit
builds (or 32 bit PowerPC builds on Intel). All other variables are then set to reasonable defaults.
For current users of the Makefile system, this commit shouldn't change much.
This changes how textures are accessed from Brushes, with the intention of simplifying
the workflow, and reducing the amount of clicking. Rather than the previous texture slots
(which didn't work as a stack anyway), brushes now have a single texture linked. Rather
than taking time having to set up your slots in advance, you can now select and change
textures directly as you sculpt/paint on the fly. For complex brushes, node textures can
be used, or for fast access, it's easy to make a duplicate of your brush with the texture
you like and assign a hotkey.
Brush textures can now be chosen from a new Textures panel in the brush tool
properties - click on the thumbnail to open a texture selector. This is done using a new
variation on the ID template - the number of rows and columns to display in the popup
can be customised in the UI scripts.
- remove console zoom operator, use WM_OT_context_cycle_int instead.
- use WM_OT_context_cycle_int for text editor zoom also (Ctrl +/- and Ctrl+MouseWheel)
from bpy.app import binary_path, version, version_string, home
can add constant variables from blender here as needed (maybe functions too... bpy.app.memory_usage() ?)
- fixed slice assignment.
- fix for slowdown where getting a slice would get the entire array and free it for every item in the array (malloc and free for arrays >32).
- fix for thick wrapped returning an array referencing the original pointer when coercing into a mathutils type failed.
TODO
- slice assignment currently only sypports lists.
- dimensions are ignored for multidimensional arrays.
Python Example.
hit_location, hit_normal, face_index = object.ray_cast(ray_start, ray_end)
- first rna func to use multiple return values
- currently casts in object space, may want to cast in worldspace too.
patch from Elia Sarti, (vekoon) with some modifications mainly for the python api.
- multiple values are returned as a typle in the order that are defined.
- added support for registered types returning multiple arguments (untested).
- renamed func->ret --> func->c_ret, since this only defines what the C function returns.
