The problem was flag-enums were being treated as regular enums, a default value of 0 was using the first enum item, whereas with flag enums we want to be able to use 0 as a default value to specify all flags are off.

also rename BVH class for consistency.
|
|
also removed unnecessary NULL checks (where the pointer was used later without checking).

replace NlaTrack.active() function with a property, since this is used everywhere else.
|
|
which caused bugs on index lookups.

Adds:
AnimData.nla_tracks.new(prev)
* (optional) prev -- add new track after this track
AnimData.nla_tracks.remove(track)
AnimData.nla_tracks.active(track)
* (optional) track -- track to set active
* returns active track
NlaTrack.strips.new(name, start, action)
NOTE: fails if the strip can't fit in the track as opposed to the
operator which will create a new track and add the strip to that.
* name -- name for new strip
* start -- start frame of new strip
* action -- action to assign to strip
NlaTrack.strips.remove(strip)

I've resolved the issue (noted in the original patch) regarding the
validation of the created strip by creating and using a "dummy
AnimData" block to solve the missing dependencies.

when using the Numpad0 feature to reset properties to their default
values.
While this implementation here is not a full/proper implementation, as
you cannot truly specify a default value for some pointers that may
require something other than NULL (i.e. nothing), this should be good
enough for the vast majority of (editable) cases which are fine if set
to NULL.
This is most noticeable with the Active Keying Set field in the
TimeLine header, where it's now possible to simply use Numpad0 to
clear it instead of using a confusing click+backspace+enter dance to
do the same thing.

This commit restores some basic functionality for retiming Grease
Pencil sketches. Some of the functionality that existed before still
hasn't been restored (namely snap/mirror tools as well as copy+paste),
though it should be possible to use this for basic retiming and
sketch-frame management again.
- There's still a lot of work required to get this up to the standard
of the rest of the animation editor code, as some of this code was
originally just hacked in based on the old-style code.
- Work is already required to not have to directly access the main db
global to get the list of Grease Pencil datablocks to show, but that
can come along with pending cleanups of the filtering code.

This meant python could do...
mesh.uv_textures[0]
...on a mesh with 1 vertex color layer instead.

when 'id' was set, but not using it.
also comment a few unused vars.
|

These were markers which belonged to an action instead of the scene,
and are used by PoseLib to keep track of where poses are.
To restore this, I've made this only available in Action/Shapekey
Editor modes, and only when an action is being shown and the "Show
Pose Markers" option in the Markers menu has been enabled. Other than
that, all the standard marker operators apply now (instead of using a
separate set of special operators).

* Viscoelastic springs between the fluid particles can simulate all kinds
of viscous and elastic substances, such as jelly and honey. This is
achieved by creating springs dynamically between neighboring particles
and adjusting their rest length based on stretching/compression.
* This nearly completes the currently intended functionality for particle
fluids. The last missing thing is a surfacing extraction algorithm,
which is needed for a proper representation of a sph fluid.
* I also cleaned up and renamed some of the fluid parameters to make the
ui a bit easier to understand.
* One addition to the patch is an option to use "initial rest length" for
the springs, which uses the lengths between the particles at the time of
spring creation as the spring rest lengths instead of interaction radius/2.
This makes the fluid keep it's original shape better (good for very
viscoelastic materials), but can create large density differences inside
the fluid (not really physically correct for a fluid).
* Viscoelastic springs are stored in point cache as extra data.

have makesrna.c omit unused _data definitions for rna funcs with no args.

- Proportional circle size is printed in header
Allows you to find out if you make it smaller when it's large
- Proportional size is clipped with view3d clip-end now
- Added the size to rna, so you can inspect values via UI and py.
|
|
- move GS() define into DNA_ID.h
- add BLI_utildefines as an automatic include with makesrna generated files.
|
|
MAKE_ID, FILE_MAXDIR, moved the generic defines to BLI_utildefines.h.
no functional changes.

we may need to preserve the previous method.

Many thanks to them!
For comparison, see here:

This fixes bugs:
#24591: Artefacts/strange normal mapping when anti-aliasing is on
#24735: Error at the Normal function.
#24962: Normals are not calculated correctly if anti-aliasing is off
#25103: Weird artefacts in Normal
This will break render compatibility a bit, but fixing this bugs would have also
done that, so in this case it should be acceptable.
Patch committed with these modifications:
* Bump method Old/3-Tap/5-Tap option in UI, 3-Tap is default
* Only compute normal perturbation vectors when needed
* Fix some middle of block variable definitions for MSVC

* Renamed children to "simple" and "interpolated" as this is
easier to explain and more descriptive than "from particles"
and "from faces".
* Also shuffled the child ui around a bit to make it clearer.
* Child seed parameter allows to change the seed for children
independent of the main seed value.
* Long hair mode for interpolated children:
- Making even haircuts was impossible before as the child
strand lengths were even, but their root coordinates were
not similar in relation to the parent strands.
- The "long hair" option uses the tips of the parent strands
to calculate the child strand tips.
* Hair parting options:
- Hair parting can now be calculated dynamically on the fly
when in 2.49 there was a cumbersome way of using emitter mesh
seams to define parting lines.
- For long hair parting can be created by a tip distance/root
distance threshold. For example setting the minimum threshold
to 2.0 creates partings between children belonging to parents
with tip distance of three times the root distance
((1+2)*root distance).
- For short hair the parting thresholds are used as angles
between the root directions.
* New kink parameters:
- Kink flatness calculates kink into a shape that would have
been achieved with an actual curling iron.
- Kink amplitude clump determines how much the main clump value
effects the kink amplitude.
- The beginning of kink is now smoothed to make the hair look
more natural close to the roots.
* Some bugs fixed along the way too:
- Child parent's were not determined correctly in some cases.
- Children didn't always look correct in particle mode.
- Changing child parameters caused actual particles to be
recalculated.
* Also cleaned up some deprecated code.
All in all there should be no real changes to how old files look
(except perhaps a bit better!), but the new options should make
hair/fur creation a bit more enjoyable. I'll try to make a video
demonstrating the new stuff shortly.

Auto-texture space now is more responsive and correct.
- on transforming it, the buttons get redrawn to show option was reset
- on enabling option, texture space is recalculated/reset
|

|
|
Object color option now is incorporated in preview render, and
in display in 3D window.
Note that Object-color is "modulating" the render result, it just
multiplies... which is very limited for practical use. This was
added for Apricot game project. The original meaning however was
to replace diffuse only... so specular and light work still correct.
ALso made header for properties editor start on top, to reflect
default (report in tracker).

bpy.data.meshes.tag = True
But this was only useful for setting so make it a function for 2.5x.

Due to popular request and usability considerations, this commit
reintroduces functionality similar to 2.4's "Draw Mode" for Grease
Pencil.
In the toolbar under the Draw/Line/Eraser buttons, you can find the
"Use Sketching Sessions" toggle, which enables this feature. This is a
per-scene setting, and defaults to off, so that the current 2.5
behaviour is still the default (i.e. the Grease Pencil operator will
only do a single stroke at a time).
With this option enabled, drawing with Grease Pencil will enter a
semi-modal state where you can draw multiple strokes without needing
to keep holding the DKEY throughout (though you'll still need to do so
to start the strokes, unless you use some toolbar buttons), while
still being able to manipulate the viewport. Header help-text prints
show the appropriate keybindings (i.e. press ESCKEY or ENTER to end
the sketching session).
Notes:
- To aid maintainability of the 3D-View toolbar code, I've taken the
liberty to factor out the groups of widgets which commonly occur in
most of the toolbars into separate functions (namely "Repeat" and
"Grease Pencil"). Perhaps it might make it slightly harder to newbies
to the toolbar code to grasp, though the physics panels are far worse
;)
- I've reshuffled some code in the Grease Pencil code to separate out
the various states of operation again more clearly, though some more
work is still needed there (TODO)
- There can now be only one Grease Pencil operator running at a time
- Redoing Grease Pencil operations where sketching sessions was
enabled still needs work. Namely, a way of delimiting the set of
points recorded into strokes is still needed (TODO)
- Ultimately, it should be possible to switch tools midway through a
session. Currently sessions are limited to only being able to be used
with a single drawing mode (TODO)
- After ending a drawing session, the titlebar contols may not work on
Windows without manually making the main window lose focus and then
regain (i.e. click on some other window in toolbar, then come back).
This may be related to (bug #25480)

Drag/drop now has a User preset for dragging threshold.
Noticed this was set to 3 pixels even, made it 5 as default.
Tablet owners can put it larger too :)
Note: the tweak-threshold (3d win) is 10 pixels now, I think
this needs another preset too, leave this for now.
Also: fixed crash in filewindow: drag .blend icon and drop it.
You can't test anything in Blender or you get a bug :)

This commit partially fixes the problems with Shapekeys from older
files, as seen from the Regression suite (relative.blend and
dolphin.blend in particular).
In older files, keyblock->slidermax was never truly set to 1.0 even
though the UI may have shown such a value (which was bizzarely being
sourced from somewhere else). Hence, after loading the files in 2.5,
the shapekeys wouldn't animate, as the value would get clamped between
0 and 0.
To fix this, I've added a version patch which corrects these
situations in old files, and I've adjusted the slider-RNA code so that
it is not possible to set up such clamping anymore.
TODO:
The fixes detailed here only make it possible for these files to work
again in 2.5. However, I haven't been able to find a way to get the
files to actually work in 2.5 without manually changing the active
shapekey (per object) after loading the files with these patches
applied. Possibly it's just some depsgraph magic needed, unless
there's still some other evil voodoo in the shapekey code

move Object.update(...) to ID.update(). since depsgraph update function can now be called on ID types.
also changed how update flags work.
obj.update(scene, 1, 1, 1)
... is now
obj.update({'OBJECT', 'DATA', 'TIME'})
Don't pass scene anymore. This was used for recalculating text but I think this is better dont in a different function.
|
|
other formats, calling operators should suffice.
