The solver was mostly implemented by John Mansour at VPAC, with help from me and with funding from the AutoCRC. The SPH formulation is due to Gingold and Monaghan, and the smoothing kernel is due to Wendland.
This solver does not replace the old one; it is available as an option. Note that the new solver uses different units than the old one. The patch page has a couple of attachments that can be used to test the new solver, particularly sphclassical_dam_s0.01_grav.blend (ignore the earlier tests). The simulation in that file compares well with a physical experimental dam break; details in a paper by Changhong Hu and Makoto Sueyoshi, also referred to on that page.
Based on patch [#30837] UV Offset Modifier
by Pawel Kowal (pkowal)
- Allows you to setup a transformation between objects to apply to UV coords.
- Option to select which axis apply to U/V.
- Option to select the UV center (needed for transformations that scale or rotate).
- Uses from/to objects in a similar way to the Warp modifier.
- Vertex group can be used to adjust influence.
Nice formatted version (pictures soon):
http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.66/Usability
Short list of main changes:
- Transparent region option (over main region), added code to blend in/out such panels.
- Min size window now 640 x 480
- Fixed DPI for ui - lots of cleanup and changes everywhere. Icon image need correct size still, layer-in-use icon needs remake.
- Macbook retina support, use command line --no-native-pixels to disable it
- Timeline Marker label was drawing wrong
- Trackpad and magic mouse: supports zoom (hold ctrl)
- Fix for splash position: removed ghost function and made window size update after creation immediate
- Fast undo buffer save now adds UI as well. Could be checked for regular file save even...
Quit.blend and temp file saving use this now.
- Dixed filename in window on reading quit.blend or temp saves, and they now add a warning in window title: "(Recovered)"
- New Userpref option "Keep Session" - this always saves quit.blend, and loads on start.
This allows keeping UI and data without actual saves, until you actually save.
When you load startup.blend and quit, it recognises the quit.blend as a startup (no file name in header)
- Added 3D view copy/paste buffers (selected objects). Shortcuts ctrl-c, ctrl-v (OSX, cmd-c, cmd-v).
Coded partial file saving for it. Could be used for other purposes. Todo: use OS clipboards.
- User preferences (themes, keymaps, user settings) now can be saved as a separate file.
Old option is called "Save Startup File" the new one "Save User Settings".
To visualise this difference, the 'save startup file' button has been removed from user preferences window. That option is available as CTRL+U and in File menu still.
- OSX: fixed bug that stopped giving mouse events outside window.
This also fixes "Continuous Grab" for OSX. (error since 2009)
adding meshes were scaling the user input values so the distance on the button didnt relate to the scale of the object added.
Now use an invoke function that scales unset default values.
- BMO_slot_copy now only copies compatible elements.
other minor changes
- don't use text.format(...), convention for UI scripts is C style string formatting.
- rename bmo_edgenet_prepare --> bmo_edgenet_prepare_exec
- float/double warning in bevel.
* Rename Legacy to Standard, it's not being deprecated as far as I know.
* Make option to toggle off Location solving work with Standard.
* Make it converge a bit better in some cases by enforcing a minimum number of
iterations before giving up.
* Move IK solver choice out of bone panel, it's an armature level setting and
should be set there.
There were two issues in scene strip rendering:
- It will skip rendering if scene doesn't have camera but uses compositor
- G.is_break will cancel preview rendering
Also removed Use Sequencer from scene's strip settings, it's not supported.
DopeSheet/Action Editor Channel menus were not working properly
They were not allowing users to choose which setting they affected, which
resulted in "protect" (i.e. the same setting as the editability toggle handles)
always being used.
Also, set hidden flags on a few internally used properties here...
Useful for bump map baking where a consistent triangulation should be enforced when baking/exporting/importing, to avoid artifacts caused by a different triangulation of the mesh by that which was used for baking by internal/external tools.
documentation is here http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.65/More_Features
Will probably add some pictures too to demonstrate the issue that is solved more clearly.
Currently using the skin modifier icon, will soon change that.
Review by Brecht, thanks!
Code to support it was lying around for long already, but not controlled by UI nicely.
Now you have in user preferences "System" tab an option to set it.
NOTE:
- it only works saving as User startup.blend, and restart Blender.
- your system should support it, no check for it is visible in UI
- tested only on iMac OSX 10.7

This commit allows you to set the RGB <-> XYZ axis colours used for things like
the mini axis indicator, grid axis indicators, manipulators, transform
constraint indicators, F-Curves (when using XYZ to RGB colouring option), and
perhaps something else I've missed. Previously, these places all used hardcoded
defines (220 * i/j/k), but the readability of these colours was often quite
poor, especially when used with certain themes.
The settings for these colours can be found under the "User Interface" section
of the themes (i.e. same set of colours is used across editors). I could have
made these per editor, but since it's unlikely that these will need to be too
different across editors in practice (+ being easier to version patch), they are
stored under the UI section.
Now tile size is setting up explicitly instead of using number of tiles.
This allows better control over GPU performance, where having tiles aligned
to specific size makes lots of sense.
Still to come: need to update startup.blend to make tiles size 64x64.
This fixes some "regressions" introduced in rev50781 which lead to much
worse solution in some cases. Now it's possible to bring old behavior back.
Perhaps it's more like temporal solution for time being smarter solution is
found. But finding such a solution isn't so fast, so let's bring manual
control over reprojection usage.
But anyway, imo it's now nice to have a structure which could be used to
pass different settings to the solver.
* Add "Toggle Full Screen" and "Duplicate Area into New Window" operators to the view menu, was missing in those 2 operators. Patch [#33076] by Harley Acheson, thanks.
* Also moved those two operators to the top in text editor, for consistency.
* Patch [#33073] Remove Extra Menu Level from Object Parent and Track
* Did not commit the icon changes here, separator line should be sufficient.
Patch by Harley Acheson, thanks!
* Add 3 more operators to the Node menu.
node.join [join selected nodes in a new frame]
node.detach [remove selected nodes from their frame]
node.links_detach [remove all links to selected nodes and try to reconnect neighboring nodes together]
Patch by Philipp Oeser, thanks!
* Shader script node added, which stores either a link to a text datablock or
file on disk, and has functions to add and remove sockets.
* Callback RenderEngine.update_script_node(self, node) added for render engines
to compile the shader and update the node with new sockets.
Thanks to Thomas, Lukas and Dalai for the implementation.
- Rename 'mesh.select_nth' operator menu item 'Every N Number of Verts' to 'Checker Deselect',
since its not just de-selecting verts (works on edges and faces too) and the term 'checker' gives a better description of the result.
- Rename 'mesh.select_by_number_vertices' to 'mesh.select_face_by_sides', since this is a face selection tool, which wasnt obvious from its name.
also remove dissolve by type menu since the option has been removed from the operator and was giving an error.
PATCH: [#32989] Activate backup files filter in File Browser
Contributed by Georg Kronthaler, many thanks!
(I just moved the icon to a different place reserved for file browser icons)
* enables the filtering of backup files in the file browser
* adds a 'filter backup files'-icon to the filter buttons
* adds new icons for backup files in list and thumbnail view
* enables file preview for the backup files
shows both title safe and action safe areas following more modern standards.
Patch #32822 by Harley Acheson, full description:
Our current "title safe" camera display option is anachronistic. It shows a
border of 10% on all edges, which used to be the recommended title safe area
for 4:3 content on standard definition CRT televisions. However we are very
unlikely to create new projects that output for SD TV at that aspect ratio.
This patch change the option to "safe areas" with and indicates the
"title safe" area (also known as "graphic safe") as well as the "action safe"
area. "Title Safe" is an area visible by all reasonably maintained sets, where
text was certain not to be cut off. "Action Safe" is a larger area that
represented where a "perfect" set (with high precision to allow less
overscanning) would cut the image off.
The current recommendation for Action Safe is 3.5% on all edges, which is the
maxiumum overscan for TVs now. The recommended title safe is now 5% vertically
and 10% horizontally for content that is of wider aspect ratio than 4:3. The
reason for the difference between horizontal versus vertical margin is because
wider content would be letterboxed on an older 4:3 television, giving it
additional margin.
