It introduces a new (py-extendable and registrable) RNA type, UIList (roughly similar to Panel one), which currently contains only "standard" list's scroll pos and size (but may be expended to include e.g. some filtering data, etc.). This now makes lists completely independent from Panels!
This UIList has a draw_item callback which allows to customize items' drawing from python, that all addons can now use. Incidentally, this also greatly simplifies the C code of this widget, as we do not code any "special case" here anymore!
To make all this work, other changes were also necessary:
* Now all buttons (uiBut struct) have a 'custom_data' void pointer, used currently to store the uiList struct associated with a given uiLayoutListBox.
* DynamicPaintSurface now exposes a new bool, use_color_preview (readonly), saying whether that surface has some 3D view preview data or not.
* UILayout class has now four new (static) functions, to get the actual icon of any RNA object (important e.g. with materials or textures), and to get an enum item's UI name, description and icon.
* UILayout's label() func now takes an optional 'icon_value' integer parameter, which if not zero will override the 'icon' one (mandatory to use "custom" icons as generated for material/texture/... previews).
Note: not sure whether we should add that one to all UILayout's prop funcs?
Note: will update addons using template list asap.
- Packing .blend files
If you work a lot with dynamic linked .blend files ("Libraries"), it's always hard to
share your work with others (or for bug reports!).
This new option packs all used external .blend files, and - on save - combines it together
in one .blend file. You can save that file on any location.
Loading a packed .blend file then loads all library data usual - not editable.
Just use unpack to save out all linked .blend files. This will only save out the files
according the directory structure as was used on linking - relative to the current .blend.
It will create new directories, so be careful with unpacking when relative paths go up.
This feature also works fine for linked compressed .blend files.
It also works for many levels deep linked .blend hierarchies.
Access is hidden for now - I need to get some people to give it serious testing first.
You can find the options via spacebar search (try pack or unpack).
- Packed data and Undo
Now all packed data is excluded from the Undo buffer storage. Keeps undo memory smaller
and makes faster redo possible.
Now scrollbars correctly hide and show, making space for the actual contents
in a region. It solves several old hacks, and puts view2d code a bit more
back in control as well.
Implementation notes:
- The view2d mask feature is working again
- The #define V2D_SCROLL_HORIZONTAL_HIDE means: "turn on hiding".
- Code for UI_view2d_region_reinit() is enforcing better standard view settings
But... two hack/patches needed to be added:
- Region panel drawing: if after generating the button panels it appears
a scroller hides or reveils, it calls all the generating code again.
(a simple scale doesn't work due to rounding differences in layout code)
- View2d code that maps 'tot' and 'cur' rects: if this code detects that
the mask changes, it calcs the map code again.
Also a bugfix (issue in 2.65)
- The left/bottom area split widget was drawing 1 pixel too large sometimes,
leaving bad trails on moving area dividers.
In case you accidentally link data in a library file from the main file, Blender would crash.
Now it survives, giving error messages to tell what to fix.
- Since 2.50, the .blends have the current file name stored
- In versions up to 2.65.0 this didn't save for files saved from startup
(i.e. files saved without loading a file)
Code now adds the file name after all, except for recovery loads.
This implements AO baking directly from multi-resolution mesh with much
less memory overhead than regular baker.
Uses rays distribution implementation from Morten Mikkelsen, raycast
is based on RayObject also used by Blender Internal.
Works in single-thread yet, multi-threading would be implemented later.
In 2.50 a new convention was added to save the filename in the .blend itself.
This to allow recovery of temp saves.
In current svn, it made old files open as if it was a saved home file (not
storing the name in header, or in file history).
Note: file handling for all recovery, remapping etc is in need for cleanup.
With the view3d 'Render Only' option, grease pencil wouldn't draw, but for OpenGL render it did.
Since grease pencil can be very useful in opengl renders, enable grease pencil drawing with 'Render Only' option in the viewport,
and add a checkbox in the grease pencil header not to draw (unchecking each layer is annoying and applies to all spaces).
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)
This commit makes BKE_image_acquire_ibuf referencing result, which means once
some area requested for image buffer, it'll be guaranteed this buffer wouldn't
be freed by image signal.
To de-reference buffer BKE_image_release_ibuf should now always be used.
To make referencing working correct we can not rely on result of
image_get_ibuf_threadsafe called outside from thread lock. This is so because
we need to guarantee getting image buffer from list of loaded buffers and it's
referencing happens atomic. Without lock here it is possible that between call
of image_get_ibuf_threadsafe and referencing the buffer IMA_SIGNAL_FREE would
be called. Image signal handling too is blocking now to prevent such a
situation.
Threads are locking by spinlock, which are faster than mutexes. There were some
slowdown reports in the past about render slowdown when using OSX on Xeon CPU.
It shouldn't happen with spin locks, but more tests on different hardware would
be really welcome. So far can not see speed regressions on own computers.
This commit also removes BKE_image_get_ibuf, because it was not so intuitive
when get_ibuf and acquire_ibuf should be used.
Thanks to Ton and Brecht for discussion/review :)
Conversion from 2.49 and older files: support for unlimited materials on
objects had an error in conversion.
Effect was that you couldn't re-assign material slots a Material, in case
you were using "link to object" option.
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.
* 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.
reported as [#29376] BMESH_TODO: remove tessface CD_ORIGINDEX layer
for a single mesh there could be 3 origindex mappings stored, one on the polygons and 2 on the tessfaces.
(CD_POLYINDEX and CD_ORIGINDEX).
as Andrew suggests, now tessfaces (which are really a cache of polygons), using origindex to point to polygons on
the same derived mesh, and polygons only store the original index values.
- Added versioning for reading old files with logic saved
- Added two more 'alt backspace' options, for copyright and registered trademark.
(also 'tm' but it's not in our default font)
This was caused by incomplete pointer mapping of the node->internal_links list in r51630, my bad. In intermediate revisions this could lead to corrupted .blend data. This patch adds a do_versions check to remove such bad links. The correct internal_links list will get restored on node update.
