Was cache referencing deleted or NULL items.
Reported by Kopias on irc
|
|
|
|
Mistakes in button expressions were previously only printed to the console.
|
|
|
|
|
|
Also enable this for headless builds too.
Calling UI_icons_init would initialize matcaps, brushes etc...
|
|
We want this even without UI, some scripts may use it in a background processing
mode to avoid too heavy process in actual 'user' blender...
|
|
Holds 30 frames in memory. Could make it check memory instead but that
should suffice for now to make sure blender does not crash on me with
movie files.
Previously the system would load eveything in memory so something like
playing caminandes in player would swap after 30 seconds in local
computer.

Some of them are just brain dead code, some are potential bugs.
|
|
|
|
Percentage properties use interaction like factors with number feedback
and easier way to go predict lower percentages.

This commit mainly:
* Exposes PreviewImage struct in RNA, including ways for user to set images data.
* Adds a new kind of PreviewImage, using a file path and IMB_thumb to get image.
* Adds a new kind of custom icon using PreviewImage, unrelated to ID previews system.
* Adds a python API (utils.previews) to allow python scripts to access those custom previews/icons.
Note that loading image from files' thumbnails is done when needed (deferred loading), not
when defining the custom preview/icon.
WARNING: for release addons who would want to use this, please keep it to a strict minimum, really needed level.
We do not want our UI to explode under hundreds of different flashy icons!
For more info, see also the release notes of Blender 2.75 (http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.75/Addons)
and the example/templates featured with Blender.

Another instance of T44376.
Crash where the Python context would access a stale pointer to the active object.
|
|
Removing a scene from the buttons window would crash from a Python operator.
|
|
Assumed the `reference` pointer is an ID, currently true, but may not always be.
Add a callback specifically for this purpose since cleaning up notifiers and space-types are different operations.

on undo due to invalid mem access.
We cannot nuke treestore in readfile's `blo_lib_link_screen_restore()`, because this will
destroy all UI-state data (like opened/closed items, etc.).
Since we cannot know for sure whether an ID pointer from tselem->id is valid here, we
have to ensure they are never invalid, i.e. to always set them to NULL when we delete them.
To do so, this commit uses a similar approach as what already exists for ID references
in WM notifiers - it extends `free_notifier_reference_cb()` to also nullify those IDs in
all outliners.
Note that some ID types are not used(shown) by outliner currently, so `TREESTORE_ID_TYPE` macro
was added, that checks whether an ID is possibly used by outliner. Avoids a few searches
in whole tree whene deleting some IDs.

This is a kind of sloppy-focus,
resolving long standing bug with loop-cut/knife/ruler /w quad-view.
Where activating a tool would lock onto one of quad-views,
especially problematic when activating from the toolbar or menus.
|
|
Term pointer is overloaded already.
|
|
D1031, implement proposal T37478 to give easy access to the online manual.
Use Alt+F1 while hovering over a button/setting.
|
|
Tried a couple of things to trigger an update/redraw for the exact right
moment (sending azone update event, timer, delayed redraw, etc) but this
seems to work rock solid without being *that* ugly.

changes from pageflip to something else
In some cases the graphic card supports quadbuffer, but not the display.
In this case it is nice to go back to a window that does not have
quadbuffer if you change back to anaglyph, interlace, ...
Otherwise you may be stuck with a flickering window
|
|
I'll enable this mode in Release builds once I figure out how to best
handle opening files that are saved with the quadbuffer mode.
In fact I think no display mode should be saved/read from a file.
Tested in Linux with NVidia 3D Vision and NVidia 3D Vision Pro with
NVidia Quadro FX 580 and Quadro FX 4600.
(kudos for the Visgraf Lab at IMPA, for having me around with all those
gadgets ;)
Thanks for Cédric Paille (cedricp) for the code snippets and tests -

Flush edits only when saving global undo. This will stop freeing of PBVH
in sculpt mode, which introduces some pretty severe freezes, especially
in dyntopo. For global undo we flush the contents of the global undo
buffer which does not include localized edits of sculpt/edit mode, so
those data will not get saved anyway.

Also usual minor i18n messages stuff...
|
|
Was included only for initial campaign.

when quadbuffer not supported
This was causing glitches when switching from/to fullscreen modes (e.g.,
side by side to anaglyph).
As for the quadbuffer errors this is part of a more complete solution to
be committed later.
|
|
|
|
Invoke assumed the filepath was never set.
Scripts couldn't invoke save-as at a custom location.
|
|
* WM_window_is_fullscreen() is not the correct test.
* Also, we no longer change window to fullscreen automatically.

Our current keymap doesn't give us enough room to make such changes in
the event system. To fix small issues caused by this, we would need to do
drastic changes in Blender's keymaps and internal handling. It was worth
a try, but it didn't work.
I can write down a more descriptive statement in a few days, but for now
I need a break of this stuff.

Speedup is non-linear, 2x-10x faster is quite normal.
Patch T43678.
- Switched from an Octree to BVH.
- Finding first points of surface no longer "wastes" density function evaluation: every result is cached.
- Use MemArena instead of using own memory management.
- Correct calculation of metaelem bounding box.
- Remove mball_count(): mballs are now counted "on the go".

* Revert 776bfa64a53191b and c3dad7953afccd4 (some X11 systems are doing
stupid things forcing me to do an extra check that completely breaks the
click type handling on other systems using the slightly changed
implementation from those commits - see T44278)
* Fix sample lines in Compositor+VSE
(And yes, this time I tested on both of my systems to make sure
everything is fine)

Implemented Features
====================
Builtin Stereo Camera
* Convergence Mode
* Interocular Distance
* Convergence Distance
* Pivot Mode
Viewport
* Cameras
* Plane
* Volume
Compositor
* View Switch Node
* Image Node Multi-View OpenEXR support
Sequencer
* Image/Movie Strips 'Use Multiview'
UV/Image Editor
* Option to see Multi-View images in Stereo-3D or its individual images
* Save/Open Multi-View (OpenEXR, Stereo3D, individual views) images
I/O
* Save/Open Multi-View (OpenEXR, Stereo3D, individual views) images
Scene Render Views
* Ability to have an arbitrary number of views in the scene
Missing Bits
============
First rule of Multi-View bug report: If something is not working as it should *when Views is off* this is a severe bug, do mention this in the report.
Second rule is, if something works *when Views is off* but doesn't (or crashes) when *Views is on*, this is a important bug. Do mention this in the report.
Everything else is likely small todos, and may wait until we are sure none of the above is happening.
Apart from that there are those known issues:
* Compositor Image Node poorly working for Multi-View OpenEXR
(this was working prefectly before the 'Use Multi-View' functionality)
* Selecting camera from Multi-View when looking from camera is problematic
* Animation Playback (ctrl+F11) doesn't support stereo formats
* Wrong filepath when trying to play back animated scene
* Viewport Rendering doesn't support Multi-View
* Overscan Rendering
* Fullscreen display modes need to warn the user
* Object copy should be aware of views suffix

Seems like a fix that is needed for some X11 systems causes this bug on
others :| Not sure if the systems that needed this fix are now still
fine (since I did a slight change to the click type check procedure),
but I need to check that on my system in the institute in a bit.
|
|
Just add KM_CLICK to the already sent KM_RELEASE, don't send a new one
for this.
This might help us to get rid of quite some glitches and workarounds \o/
(why didn't this come earlier to my mind? :S)
