Finally in 2.5 branch :)
Still things to do, but will continue working in here. I won't bother
repeating the commit messages from the last year or so, however I've
written up some technical docs to help Ton/Brecht/etc review and find
their way around the code:
http://wiki.blender.org/index.php/User:Broken/VolumeRenderingDev
That above page has some known issues and todos listed, but I'm still
interested in bug reports.
Credits for this code:
* Matt Ebb
(with thanks to Red Cartel/ProMotion Studios)
* Raul Fernandez Hernandez (Farsthary) for patches:
o Light cache based multiple scattering approximation
o Initial voxeldata texture code
o Depth Cutoff threshold
* Andre Susano Pinto for BVH range lookup addition
* Trilinear interpolation adapted from pbrt
* Tricubic interpolation from libtricubic
New Actions can now be added again from the Action Editor.
There are no guarantees that this works totally safely yet (reference counting may be quite off), so you've been warned.
Wrapped the Keying Sets API with RNA Functions so that they can now be called from Py-Scripts. This will ultimately be useful for riggers to create Keying Sets which can get loaded up/created for animators to use after importing their rig.
I've created a demo for this, which can be found at:
http://www.pasteall.org/blend/552
Notes:
- Kazanbas, I've had to create a rna_scene_api.c here to hold some of the relevant functions. Hopefully this won't cause you too much pain when you do your next merge from 2.5 to your branch ;)
- I've noticed that there seem to be a few cases mentioned in the demo which don't totally work yet. I'll commit some fixes for those later.
* F-Modifiers on F-Curves can now taken into account when calculating the extents of actions. This is used when there are some NLA strips and some action with some F-Modifiers is being played back on top of those.
* The toggles in the NLA channels list now respect the width of the list instead of using a hardcoded position. This means that clicking on these toggles when the list is resized works again.
* Inserting keyframes now takes into account whether the F-Curve was editable or not.
* Editing keyframes in animation editors now sends proper depsgraph updates instead of just tagging the relevant objects.
Thanks JiriH for reporting these bugs.
*enable non-2^n textrues for all gfx cards which support it.
* try to enhance the visual quality under linux a bit when gfx card doesn't support it (still errors visible)
The 'Show Sliders' option for DopeSheet and Graph Editors now works again. When this option is enabled (it is disabled by default), a slider (or combobox) is shown beside the mute/lock toggles for F-Curves. Editing the slider will result in a new keyframe being added on the current frame.
So, for all the (ex)-Maya animators out there, you can now animate in a channelbox-like way. :)
Also in this commit:
* Fixed some warnings in modifier.c from previous commits there
* Fixed some refresh problems with DopeSheet channel list (which were only obvious after adding back the sliders)
* Removed the old/unrestored and nasty slider code used in the past by the Action Editor only.
Made toggle buttons less wide, with less extra space around them
Made number widgets wider to allow larger numbers, such as the current frame field in the timeline.
Patch by Lorenzo Pierfederici (lento). Many thanks!
* Ported some more menus to python (Pose, Particle...)
* Some cleanup and reorganization in the python file to reduce code. :)
* Cleanup of old C buttons code.
Changed the rounding of action buttons. The round style looked pleasing when they were isolated, viewed by themselves, but looked terrible when grouped, or at small sizes with icons as it was often used. The old Filebrowse or Render This Window buttons were examples of how badly they looked with an icon, and the rounding in the tools area made for some weird visual shapes. When combined in groups of widgets, such as the datablock selectors it looked even weirder, because one side of the group would be square and the other would be round, causing some spatial clashes.

Also tweaked the tools sub-area color which stood out as being much brighter than the rest of the UI. When the tools area was open in the default layout, the overall impression was asymmetrical, non-harmonic.
Previously the only way to detect if the mouse moved over a different object was to enable true-level-triggering and have a python script detect the change.
When the Pulse option is set, focusing on a different object pulses true.
Python attribute is focusSensor.usePulseFocus.
This is similar to the collision sensors pulse option where changes in the set of collision objects generates an event too.
Found this functionality missing when trying to make a logic demo that used mouse-over with overlapping objects.
This solves one of the last remaining hurdles for
volume rendering. Previously it always used ray
tracing to shade other objects inside or behind the
volume. This meant that said objects would look
aliased, unless you used Full OSA on the volume
(which is slow!). As well as this, it meant that you didn't
get a good alpha channel out of the volume to use for
compositing, similar to ray refracting materials.
This commit enables z transparency for volume
materials. Although it can be potentially less
physically correct, in most situations there's no
difference, and you get the benefit of nice sampling for
other objects and an alpha channel for compositing too.
For now have pyrna_struct_as_srna look in the dict first for __rna__ before using PyDict_GetItemString.
Somehow __rna__ is not calling the pyrna_struct_getattro function, python find it first.
The only relyable way to get the rna from python currently is.
bpy.types.SomeType.__dict__['__rna__']
Fixed some typos made in previous commit. Hook Modifier should now work correctly again (and also for newly added Hook relationships)
Notes:
* To add a hook, you currently need to perform the following steps
1) add modifier from menu (no operator in EditMode)
2) specify the object (and/or bone to use as the hook target)
3a) in EditMode, select the vertices you wish to be affected by the hook, and press 'Assign'
3b) alternatively, fill in the vertex-group field for the Vertex Group which contains the vertices to be affected
4) press 'Reset' (to make sure hook will behave correctly)
5) optionally, also press 'Recenter' if the hook position isn't right...
* BUG ALERT (Brecht/Ton): it is impossible to clear the vertexgroup/bone fields once you have assigned some value. Doing backspace+enter (or any other variation) will always result in the first item in the search menu being used.
Moved WeightPaint/VertexPaint toggling hotkeys to the same place that the ones for PoseMode/EditMode are defined. This means that the hotkey for toggling PoseMode works again (instead of being overwritten by WeightPaint).
* Disabled multires subdivide button in editmode (again)
SVN weirdness:
I already did this in r22447. Somehow it got changed back -- but I can't find any log of it getting reverted, either in my email or on p.b.o. This is extremely weird!
