*** use-case:
"I have 10 reference images that overlap each other and every time I want to see one, I need to change the transparency of all the others.
therefore it would be nice to have a little button by each menu to allow enable/disabling individual background images"
To avoid subversioning bump I created a define that is negative (DISABLED) and of course a rna that is a boolean_negative.
Talked with Campbell and he actually prefers this way over do_version, so there it goes.
In some cases solving can take a while (especially when refining is used)
and keeping interface locked is a bit annoying. Now camera solver is moved
to job system and interface isn't locking.
Reporting progress isn't really accurate, but trying to make it more linear
can lead to spending more effort on it than having benefit. Also, changing
status in the information line helps to understand that blender isn't hang
up and solving is till working nicely.
Main changes in code:
- libmv_solveReconstruction now accepts additional parameters:
* progress_update_callback - a function which is getting called
from solver algorithm to report progress back to Blender.
* callback_customdata - a user-defined context which is passing
to progress_update_callback so progress can be updated in needed
blender-side data structures.
This parameters are optional.
- Added structure MovieTrackingStats which is placed in MovieTracking
structure. It's supposed to be used for displaying information about
different operations (currently it's only camera solver, but can be
easily used for something else in the future) in clip editor.
This statistics structure is getting allocated for time operator is
working and not saving into .blend file.
- Clip Editor now displays statistics stored in MovieTrackingStats structure
like it's done for rendering.
This commit implements:
- Configurable settings for newly creating tracks
Now it's possible to set tracking algorithm and it's settings for
all newly creating tracks including manual tracks creation and
tracks creation by "Detect Features" operator.
- Moves margin, frames limit and adjust frame inside per-track
settings.
Was request from Francois for this.
- Adjust Frames replaced with menu called Pattern Match where it's
possible to choose between matching pattern from keyframe frame
or from previously tracked frame.
Didn't see somebody used adjust frames values differ from 0 and 1,
and this menu should make things more clear here/
- curve map insert point had a nested loop which used the same value to index different arrays.
- dynamic paint used ternary operator where both outcomes were the same.
This issue it totally related on issue with changing object datablock.
For curves it used to guess object type from curve datablock based on
count of control points in V direction.
This quess fails in case when SurfCircle datablock is trying to be reused
by another surface object or as another sample empty surface databouck used
to be treated as curve.
Store type in Curve when creating new Curve datablock which is used in
this object type quessing function.
Note: Previously saved files wouldn't change behavior at all.
move these checks from creator into BKE's image.c, this way we dont need the defines for creator, scons was missing DDS, HDR & Cineon for example and nobody noticed.
by Gaia Clary.
Rationale: the name was confusing and not always used consistently, and this
map itself is not something that can be layered, rather the map can be used
as texture coordinates in some layered setup.
The original intent was to indicate this contained more than just UV's, but
the game engine settings have already been moved out, and apparently users
didn't really get this from the name anyway.
* Wave simulation speed doesn't anymore depend on surface size, but uses relative distances instead. This change will likely change simulation behavior on existing saves, but can be easily tweaked back using the "Wave Speed" parameter.
* Added a new wave brush type, "Depth Change". It uses the change of brush intersection between frames, giving a better looking "wake" for moving objects. It also doesn't leave any "dent" to the surface while remaining still.
- Changed some names so now people who aren't really familiar with
motion tracking can understand what they exactly means
- Also cleaned up and rephraded some descriptions
- Changed behavior of operator which creates empty for 2d tracks:
now it operates on all selected tracks rather than active track only
- Added checkbox to enable/disable rotation stabilization
- use NULL rather then 0 for pointers
- use static functions where possible
- add own includes to ensure func's and their declarations don't get out of sync.

This patch adds the individual invert options for the turntable mode too. In turntable mode there are only the rotate and roll and no tilt axis to invert.
- Move tracking-related constraints to own section in list
Currently there are only two constraints, so can look a bit odd,
but it'll be other constraints like "Object Solver" and so.
- Move motion-tracking parameters from 3D viewport Display panel
to it's own panel.
- Get rid of "Bundle" in 3d viewport. It's quite obvious that it's
a 3D representation of tracks is used in 3D viewport and it shouldn't
be so confusing for artists now.
- Also get rid of "Bundle" in Follow Track constraint.
Old files can change a bit because of changes in DNA.
- Also get rid of "Bundles" in operator which creates vertices cloud
from 3D position of tracks.
- Rename "Principal Point" to "Optical Center" in the interface.
- Add support for refining the camera's intrinsic parameters
during a solve. Currently, refining supports only the following
combinations of intrinsic parameters:
f
f, cx, cy
f, cx, cy, k1, k2
f, k1
f, k1, k2
This is not the same as autocalibration, since the user must
still make a reasonable initial guess about the focal length and
other parameters, whereas true autocalibration would eliminate
the need for the user specify intrinsic parameters at all.
However, the solver works well with only rough guesses for the
focal length, so perhaps full autocalibation is not that
important.
Adding support for the last two combinations, (f, k1) and (f,
k1, k2) required changes to the library libmv depends on for
bundle adjustment, SSBA. These changes should get ported
upstream not just to libmv but to SSBA as well.
- Improved the region of convergence for bundle adjustment by
increasing the number of Levenberg-Marquardt iterations from 50
to 500. This way, the solver is able to crawl out of the bad
local minima it gets stuck in when changing from, for example,
bundling k1 and k2 to just k1 and resetting k2 to 0.
- Add several new region tracker implementations. A region tracker
is a libmv concept, which refers to tracking a template image
pattern through frames. The impact to end users is that tracking
should "just work better". I am reserving a more detailed
writeup, and maybe a paper, for later.
- Other libmv tweaks, such as detecting that a tracker is headed
outside of the image bounds.
This includes several changes made directly to the libmv extern
code rather expecting to get those changes through normal libmv
channels, because I, the libmv BDFL, decided it was faster to work
on libmv directly in Blender, then later reverse-port the libmv
changes from Blender back into libmv trunk. The interesting part
is that I added a full Levenberg-Marquardt loop to the region
tracking code, which should lead to a more stable solutions. I
also added a hacky implementation of "Efficient Second-Order
Minimization" for tracking, which works nicely. A more detailed
quantitative evaluation will follow.
Original patch by Keir, cleaned a bit by myself.
Warning!
Angles in nodes have just been moved to consistant Radians values (ANGLE subtype of RNA Float property). You will still see them as degrees in the GUI, though, unless you chose otherwise in Scene properties, Units panel.
Conversion from degrees to radians for old files is obviously done at loading time, but if you use a mixed pipeline of trunk and releases, be carefull!
Loading a 2.60.4 file (or higher) into any previous version of Blender, your angles in nodes will have odd values (well, radians interpreted as degrees)!
And if you save such file in a pre-2.60.4 version, the angle node values will be converted again when loaded in Blender 2.60.4 or higher...
This affects following nodes:
* Compo: Rotate, Defocus, ChromaMatte, Glare and DirectionalBlur
* Shader: Mapping
And all future code using the TexMapping struct’s rotation part (its rot memember is now in radians).
* Reuse the placeholder "eModifierType_EmptySlot" for the new Ocean modifier.
WARNING:
DO NOT use Ocean modifier in trunk with a revision below this commit! Files won't load then!!
* Renamed "Sharp" proximity falloff to "Constant".
* Added a new "Negate Volume" option for "Volume + Proximity" brush.
* Possible fix for random particle clipping errors.
