- fix: user pref, window title was reset to 'Blender' on tab usage
- Undo history menu back:
- name "Undo History"
- hotkey alt+ctrl+z (alt+apple+z for mac)
- works like 2.4x, only for global undo, editmode and particle edit.
- Menu scroll
- for small windows or screens, popup menus now allow to display
all items, using internal scrolling
- works with a timer, scrolling 10 items per second when mouse
is over the top or bottom arrow
- if menu is too big to display, it now draws to top or bottom,
based on largest available space.
- also works for hotkey driven pop up menus.
- User pref "DPI" follows widget/layout size
- widgets & headers now become bigger and smaller, to match
'dpi' font sizes. Works well to match UI to monitor size.
- note that icons can get fuzzy, we need better mipmaps for it
blender_add_lib now takes a separate include argument to suppress warnings in system includes (mostly ffmpeg & python).
also only build wm_apple.c on apple+carbon configuration.
for durian we had camera rigs which needed to have the parent transformed rather then the camera, for this reason I made fly mode fly the parent rather then the camera its self.
Make this a preference and use this for view camera/view locking too.
This patch adds adjustment layer tracks to the sequencer and does some cleaning
up of the code.
What's an adjustment layer?
Think of it as an effect track, which takes no explicit input, but alters
the output of everything down the layer stack.
So: you can add several stages of color correction with it.
And: you can even use it with metastrips to group several adjustments together.
- follow rotate/pan/zoom/dolly operators.
- auto-depth preference works.
- smooth view navigation supported.
- view selected, all & numpad operator work too.
TODO
- deal with camera transform locked axis
- find a way to move/zoom the frame while the camera is locked (if it turns out to be a problem).
The main purpose for this is to allow rendering motion blurred blender fluids in external renderers (eg. http://vimeo.com/21870635 ).
Python code snippet for interpreting this data here: http://www.pasteall.org/21577 . Cleaned up some ugly hacks in this area too
* Also added read-only access to scene.subframe to RNA - setting current frame and subframe should still go via scene.frame_set()
Patch to make the radial control more generic with RNA. Patch was
reviewed here: http://codereview.appspot.com/4280080/
Prior to this update, the radial control code in trunk had generic
parts of the radial control implemented as an incomplete operator
within WM. Then each different user of the radial control had to
implement a separate operator to actually pass in specific brush data
-- e.g. sculpt's brush size, vpaint's brush size, etc.
This patch removes all the extra operators and makes the WM operator
do everything. It now takes several RNA path strings as its properties
-- the only required property is data_path, which specifies the data
to be modified by the radial control. The other paths affect display
in various ways, e.g. rotation, color, etc.
In addition to decreasing some duplicate paint brush code, these
updates make it pretty easy to enable radial control for other
purposes (and it can be set up entirely though python or keymaps, no
extra C code needed.)

This adds support for empties to reference images and draw in the 3D view.
Modifications from the original patch.
- use an empty draw 'image' type
- use image aspect ratio for non-square-pixels
- when the image is not found, still draw the frame.
Added new option to find panel of space text which toggles
case-esensitive search.
Additional changes:
- Send NC_TEXT|NA_EDITED when removing markers in find_and_replace modifier
this prevents "sticked" markers which disappears on first redraw when
search text wasn't found
- Do not show "Text wasn't found" error when text to be searched is contained
in the end of buffer and it's selected. Replacing/marking used to happen, but
this popup message was really annoying for this case.
TODO: It's incorrect to use UI_GetThemeColor4ubv from this operator
- Constructive modifiers are enabled by default in sculpt mode.
- There's option to disable all constructive modifiers in the "Options"
panel of toolbox in sculpt mode,
- Use one column in options panel to make strings easier to read
- No modifiers would still be applied on multires
simple modifier, almost like a hook, except it can deform with 2 object source -> target, has option to preserve rotation and use different falloff types.
Made some improvements to the point density texture. Added support
for tweaking the falloff with a custom curve. Also coded new
falloff types based on the age or velocity of particles.
Also added a test break check to the volumetric shade cache code,
to avoid nasty hangups from the preview render (on render, exit,
etc).
- continue zoom now uses the same options as dolly (hoz/vert & invert).
- remove event mouse coord hack to bypass touchpad zoom invert, instead pass invert as an argument.
Actions now get tagged with an ID-code, which is used to determine
what ID-blocks they can be assigned to. This ensures that material
actions cannot be assigned to the object-level for example.
* Action lists in general will now show only the actions that can be
set for that particular slot. This prevents selection of invalid
actions, and helps cut down the list of actions.
** An exception here is the Add Action Clip in NLA Editor, which will
show all actions but will only add where appropriate. This is because
it's not easy/possible to tell in advance which blocktypes to filter
for when building this list. (TODO?)
* The "Action Editor" is now strictly for object-level action
editing+setting now. This avoids repeateded confusion by people who
try using this to view their shapekey actions, which should go to the
Shape Key Editor instead!
** A context switcher for the legitimate times where this capability
might come in handy is still being investigated.
* "Floating" actions (i.e. actions in some action_library.blend) are
NOT able to be automatically tagged until they are assigned to some
datablocks (i.e. loaded onto the rig + played back once). It is
possible to write scripts that check for certain RNA-paths and "guess"
what datablocks they work on, but it is recommended that you load up
the Datablocks Viewer, and go through such actions by hand, setting
the "ID Root Type" property as appropriate per action.
I'm finally yielding to months of feature requesting, and adding
support for filtering F-Curves by name, where the "name" here is the
text which is displayed for each F-Curve in the Animation Editor
channel lists.
To use, just enable the magnifying-glass toggle on the DopeSheet
filtering settings, and enter a snippet of text to find within the
names of channels you wish to filter. This is case insensitive, and
currently doesn't support any wildcard/regrex fanciness.
Some examples:
loc <--- location curves only
x loc <--- x location curves only
x eul <--- x rotation curves only
rot <--- rotation curves only
etc.
restore, would not get their dependencies updated when they became visible.
It happend with a shrinkwrap modifier in these reports, but could happen with
other modifiers too.
Now we keep track of which layers have ever been updated since load, and tag
objects on them to be recalculated when they become visible.
* Separate out selection flags from file type flags, was bothering me since forever ;)
* Also renamed ACTIVEFILE to SELECTED_FILE to better reflect actual usage in code.
* Fix crash introduced with last commit, better check for valid selection
Patch from Alexander Kuznetsov: Real-time File Selection, thanks for the contribution.
Still made a few minor changes from latest patch:
1. Rename SELECTEDFILE to HILITED_FILE, since we are not actually selecting the file, but previewing/highliting the possible selection.
2. Also made this clearer by not drawing the files as selected, but just highlight them.
3. Removed the Select/Deselect toggle when clicking on file, will be committed separately soon.
* The old collisions code detected particle collisions by calculating the
collision times analytically from the collision mesh faces. This was
pretty accurate, but didn't support rotating/deforming faces at all, as
the equations for these quickly become quite nasty.
* The new code uses a simple "distance to plane/edge/vert" function and
iterates this with the Newton-Rhapson method to find the closest particle
distance during a simulation step.
* The advantage in this is that the collision object can now move, rotate,
scale or even deform freely and collisions are still detected reliably.
* For some extreme movements the calculation errors could stack up so much
that the detection fails, but this can be easily fixed by increasing the
particle size or simulation substeps.
* As a side note the algorithm doesn't really do point particles anymore,
but uses a very small radius as the particle size when "size deflect" isn't
selected.
* I've also updated the collision response code a bit, so now the particles
shouldn't leak even from tight corners.
All in all the collisions code is now much cleaner and more robust than before!
In addition don't store unfinished links in the nodetree->links list any more. This makes code a bit safer because all links in that list can be considered valid now. The temporary bNodeLinkDrag structs used by the modal linking operator are now also stored in a list in SpaceNode, so these links can be drawn too (this separation also allows different display of temporary links, e.g. currently they are drawn on top of all nodes).
the same, but big changes have happened both on the outside and on the inside.
New UI:
* The old parameters were quite true to the underlying algorithm, but were quite obscure
from a users point of view. Now there are only a few intuitive basic parameters that
define the basic fluid behavior.
** By default particle size is now used to determine the interaction radius, rest
density and spring rest lengths so that it's easy to get stable simulations by simply
emitting particles for a few frames and adjusting the particle size (easy when the
particle size is drawn) so that the fluid appears continuous (particles are touching
eachother).
** Stiffness - in reality most fluids are very incompressible, but this is a very hard
problem to solve with particle based fluid simulation so some compromises have to be
made. So the bigger the stiffness parameter is the less the fluid will compress under
stress, but the more substeps are needed for stable simulation.
** Viscosity - how much internal friction there is in the fluid. Large viscosities also
smooth out instabilities, so less viscous fluids again need more substeps to remain
stable.
** Buoancy - with high buoancy low pressure areas inside the fluid start to rise against
gravity, and high pressure areas start to come down.
* In addition to these basic parameters there are separate advanced parameters that can
either be tweaked relative to the basic parameters (or particle size) or defined
independently.
** Repulsion - the stiffness parameter tries to keep the fluid density constant, but this
can lead to small clumps of particles, so the repulsion keeps the particles better
separated.
** Stiff viscosity - the normal viscosity only applies when particles are moving closer to
eachother to allow free flowing fluids. Stiff viscosity also applies smoothing to
particles that are moving away from eachother.
** Interaction radius - by default this is 4 * particle size.
** Rest density - by default this is a density that the particles have when they're packed
densely next to eachother.
** Spring rest length - by default this is 2 * particle size.
* There are also new options for 3d view particle coloring in the display panel to show
particle velocity and acceleration. These make it easier to see what's happening in the
fluid simulations, but can of course be used with other particles as well.
* Viscoelastic springs have some new options too. The plasticity can now be set to much
higher values for instant deletion of springs as the elastic limit is exeeded. In addition
to that there is an option to only create springs for a certain number of frames when a
particle is born. These options give new possibilities for breaking viscoelastic fluids.
New in the code:
* Most of the fluids code is now thread safe, so when particle dynamics go threaded there
will be a nice speed boost to fluids as well.
* Fluids now use a bvh-tree instead of a kd-tree for the neighbor lookups. The bvh-tree
implementation makes the code quite a bit cleaner and should also give a slight speed
boost to the simulation too.
* Previously only force fields were calculated with the different integration methods, but
now the fluid calculations are also done using the selected integration method, so there
are again more choices in effecting simulation accuracy and stability. This change also
included a nice cleanup of the whole particle integration code.
As the internals are pretty stirred up old particle fluid simulations will probably not
work correctly straight away, but with some tweaking the same level of control is still
available by not using the "relative versions" of the advanced parameters (by default these
are not used when loading old files).
Option for tagging creases (Ctrl+RMB) to also re-unwrap the mesh.
In 2.42 this could be done by setting rt==8 (very hidden), now its a little less hidden (in the toolbar).
