Using acos(dot(u, v)) to find the angle between two vectors is quite
inaccurate, and there's a better way to do it, as explained here:
http://www.plunk.org/~hatch/rightway.php
Also changed the use of atan for computing roll to atan2 in some places,
the latter avoids accuracy and division by zero issues.
steps, making it all look much nicer!
To keep this interactive, no re-calculate event is generated. A user has
to force that by editing nodes or click on a socket.
Composite: Rotate and Scale nodes ignored the translation offset.
I've added rotating and scale of offset vector, but this should become a
nice 2d matrix[3][3].
Also fixed: the call "pass_on_compbuf" now has correct handling for
using duplicate buffer rects. Can be used safely again to migrate input
buffers to the output when no operation happened. This makes translate
node faster again btw.
The sanity check I added for rare 64-bit cases where sizeof(int)==8
wasn't working so well; part of the code wasn't even committed
(the function BLO_test_64bits I wrote specifically) and since 64-bit
systems like those are so rare and since the code seemed kindof bad,
I just cut it all out.
I wonder how this survived so long in Blender... (2005/03/09 commit).
Reason was the call to BPY_free_screen_spacehandlers(sc) in kernel,
which was freeing up scripthandlers in a weird way. That call is
really obsolete. The real freeing should go in the del_area() call,
to prevent copying and deleting area in the UI to go wrong.
(Crash happened in testing timeline markers, and holding CTRL+Uparrow
a while...)
- now draws on correct height
- selection is clipped correctly (did entire height)
- made showing scene markers default
Actually this implementation should have been a patch review... it was
done with entirely duplicating the code from timeline.c, whilst re-use
and generalizing markers has a preference. That way markers can become
supported in any time-based editor.
Will send an extensive review to Joshua Leung :)
IDProperties now have a sanity check to prevent different ID properties
in the same group from having the same name. The appropriate code has been
added to the python bindings to catch this and raise an error.
This commit adds a new constant dict to the top Blender module
called PropertyTypes. This dict represents all the ID Property
constants: STRING, INT, FLOAT, ARRAY and GROUP.
Further python work, including epydocs, are forthcoming.
This commit adds file reading/writing of ID properties to all ID types,
and also adds python access for NMesh, Mesh, Scene and Image. Note
that the file reading code might need some more work for certain
future/planned features to save right. Also I updated a few comments in idprop.c.
This commit adds supports for per-ID properties to blender.
See http://mediawiki.blender.org/index.php/BlenderDev/ID_Property
for more information on how it all works.
ID properties are accesable by python; but note that
bindings have only been added to Object and Material thus
far. However adding more bindings is easy and I plan
on adding several more hopefully within an hour of this inital
commit.
A generic UI panel is also planned, that will go wherever its
needed; for example in the material buttons, editing buttons, etc.
I'll likely submit the initial code for that as a patch, though,
so matt and ton and others can go over it and make sure it's
all good. :)
VERY important, if you intend to use ID properties please
go to http://mediawiki.blender.org/index.php/BlenderDev/PropertyStandards
and start writing the appropriate standards for it.
and also fixes some further segfaults.
Now it is possible to 'surf' (jump) to different markers. This is only
possible through the hotkeys for this:
* Page Up - Next Marker
* Page Down - Previous Marker
These hotkeys match the ones in the timeline. In order to do so,
I've had to reassign two (rarely used/obscure) hotkeys:
* 'Ctrl Page Up' is now move selected action channel up (was Page Up)
* 'Ctrl Page Down' is no move selected action channel down (was Page Down)
I should also mention here that
* 'Shift Page Up' is move action channel to top
* 'Shift Page Down' is move action channel to bottom
Fixes Bug #5239 reported by Anders Gudmundson:
- Sequencer eats memory like popcorn with metastrips
- Crash on gaps in metastrips
Both were introduces by my last patch that added "Speed Control".
I also forgot to add "Speed Control" and "Color" to the "Add"-menu.
(Simply haven't noticed, I use the spacebar all the time...)
Added a less 'strict' solver step size control.
Cuts down needed loops to a 1/5 in 'regular' collision situations.
So why be a maths smartass when we want to do a skirt in a breeze :)
Is on by default, old mode can be turned on with the 'O' button beside the RK-limit.
Some minor fixes to the UI
- Weight paint options now also show in Nkey panel
- added uiNewPanelTitle() in interface API to rename panels. In use now
for the Nkey panel title.
(Note: original name is identifier, do not change that)
Static particle option: maximum length. Button is next to "Vect" in first
particle panel. This allows weird forcefields and wind to act without
extreme long strands.

Bugfix: Beziers in curve didn't calculate the tilt values correctly for
the endpoint and not for all handle types. That way deforming curves didn't
extend the tilted deform either. (IRC report by Jahka)
2)
If you setup a Proxy for Armatures, the protected bones now have an error
pupup for buttons and for some of the tools in 3d window (constraint edit
mostly).
Also the Bones Panel shows a note when the bone is not editable.
The (#ifdef WITH_ICONV) option to draw International Fonts in file window,
didn't set the rasterpos OK for textured fonts.
Also: cleaned up code so it doesn't complain soo much without iconv.

* There is now a feature to (de)select all markers. Can be found in menu or
via the hotkey Ctrl A
* The 'Markers' menu is now not drawn when marker set is 'None'
* Some other minor code cleanups
Additional Notes:
* I'm still trying to track down the cause of a bug which means that you can't
select more than one marker (with RMB clicks) at once. For now, just use
borderselect
* Now Blender doesn't segfault when trying to add a marker to nowhere.
(Missing checks for NULL marker lists)
* Line widths should now not be widened after drawing markers.
Thanks malefico and Plumiferos team for testing
Added a simple check to a number of editing operations. If multires is enabled,
an error is displayed and the operation is cancelled. This includes adding and
deleting verts/edges/faces, and anything that would reorder elements.
Loadsa new compo nodes, most added in new menu "Mattes".
- Seperate into YCC
- Combine YCC
- Seperate into YUV
- Combine YUV
- (Chroma) Difference Matte
- Chroma Key
- Luminance Key
- Color Spill correction
Main problem is missing docs still... Bob is working on it, he'll also
make tooltips for all buttons.
Some UI things might change too, like more clear names.
