This commits merges object tracking implementation from tomato branch.
Summarized changes from branch:
- Added list of objects to be tracked. Default there's only one object called
"Camera" which is used for solving camera motion. Other objects can be added
and each of them will have it;s own list of tracks. Only one object can be used
for camera solving at this moment.
- Added new constraint called "Object Tracking" which makes oriented object be
moving in the save way as solved object motion.
- Scene orientation tools can be used for orienting object to bundles.
- Object has got scale to define "depth" in camera space.
- All tools which works with list of tracks or reconstruction data now
gets that lists from active editing object.
- All objects and their tracking data are available via python api.
- Improvements in witness cameras workflow,
For premultiplied alpha images, this makes any color space conversion for the image
or render output work on color without alpha multiplied in.
This is typically useful to avoid fringing when the image was or will be composited
over a light background. If the image will be composited over a black background on
the other hand, leaving this option off will give correct results.
In an ideal world, there should never be any color space conversion on images with
alpha, since it's undefined what to do then, but in practice it's useful to have
this option.
Patch by Troy Sobotka, with changes by me.
- Enable bicybic filtering fir image displayed in track preview
- Option to show grayscale content of track preview
- When some channels are disabled, display exactly the same
content of preview image which is sending to tracker library.

This was a test drive to see how painful the merge will be.
Next batches are:
- use desktop option for fullscreen
- multisampling option
- bullet collision mask
- python
- storage (vbo, dl, ...)
- lighting
[lighting still needs review]
[python could use review, although it should be straightforward]
[storage should be tested more I think]

36991:
==UI==
* Made some options available in Blender Game that were only available in Blender Render (camera resolution, animation fps)
* Created a panel for the embedded player
* Renamed the FPS option for the standalone player to Refresh Rate
* Moved framing options to display
* Made a button to launch the blender player from within blender (only tested on windows for now)
37059:
==UI==
* Added the option to change the exit key for the BGE. The UI currently just sets a number, and this feature most likely does not work for blenderplayer yet. More work on this to come.
* Removed the physics settings from the scene panel for the BGE.
* Added an Add menu in the logic brick header.
37157:
Making the bake options available in Blender Game
37416:
Making the exit key UI element accept key presses instead of numbers. It still does not work for the Blenderplayer, and it does not limit the input to key presses (other events don't work for exiting)
37497:
Some more work on getting the exit key to work in the Blenderplayer.
Input is now restricted to keyboard events only for the exit key UI.
37498:
Some clean up from the last commit.
The exit key setting affects the Blenderplayer now.
37499:
Cleaning up some duplicate code. Now the reverseTranslateTable for converting blender key codes to ketsji key codes is only defined in BL_BlenderDataConverter.
37501:
Centralizing the exit key methods to the keyboard devices. This should make it easier to get exit key control to the python API.
[37517: committed previously]
37522:
Moved control of the exit key away from the keyboard devices, and moved it to ketsjiengine.
Added setExitKey and getExitKey to the python API
39036:
A couple of the doversions were in the wrong spot. This should fix some issues with the exit key not being set.

Object *ob;

ob->col_group = ob->col_mask = 1;
}
Added slider to define scale of object solution which is used to define
"depth" of object relative to camera position. This slider effects on all
"users" of object solution such as bundles display, constrained objects and so.
Added new operator called "Set Solution Scale" to set real scale for object
solution based on real distance between two bundles reconstructed for this object.
New slider and operator can be found on "Object" panel in toolbox when in
reconstruction mode and active tracking object isn't a camera.
Object used to be parented to active camera which isn't very convenient when
working with witness cameras.
Now parent camera can be specified in constraint (if it's not specified, active camera is used)
- Bundles selection is now available for object's bundles
- If bundles selection wasn't changed in 3D viewport, fallback to regular
object selection, so objects behind bundles can be selected
- Snap cursor to selection now respects object's bundle selection
- Object and rack name now can be selected from list in constraint settings
- Added preset for tracks used for object tracking
Made Object Solver operator parent object to scene's camera. Behavior is pretty much
familiar to Child Of constraint -- it stores inverted transformation matrix which gives
constant offset in parent's space.
Current files would open incorrect, to make object aligned well again, just press
"Set Inverse" button in Object Solver constraint.
Fixed orientation operators so now they should work in all cases.
Also changed behavior of Set Origin operator which now sets origin to the median
point of all selected tracks/
This commit introduces bicubic bump map capabilities for the viewport for OpenGL 3.0+ capable GPUs.
To use the functionality change the bump mapping method to "best quality"
Previous "best quality" setting becomes "medium quality" now.
For non OpenGL 3.0 GPUs this becomes the same as "medium quality"
Also:
* added tooltip descriptions to the bump method settings.
* modified the shader to ommit extraneous matrix multiplications for matrices already provided by OpenGL.
Bicubic shader by Morten Mikkelsen. Thanks a lot!
Oh...and FIRST!
* even offset, uses same shell distance method as solidify to give even with beveled faces.
* distance offset, this is mostly for compatibility with the modifier in trunk which uses the bevel width as a distance rather then a percentage. at the moment this is awkward for the operator since it makes percent act differently where the 0-1 range doesnt make sense.
still need to bring back more options from trunks bevel modifier.
- Rotation now happens around initial stroke location rather than around scene origin
- Added slider for rotation strength which helps in cases only few rotation is needed
to be to increase the precision of such strokes
Fix based on Brecht's idea: use Blender's conversion from quat or axis angle to euler and back. Euler rotations are left alone so their rotation order is respected
Keir's comment:
Add support for detecting tracking failure in the ESM tracker component of
libmv. Since both KLT and Hybrid rely on ESM underneath, KLT and Hybrid now
have a minimum correlation setting to match. With this fix, track failures
should get detected quicker, with the issue that sometimes the tracker will
give up too easily. That is fixable by reducing the required correlation (in
the track properties).

Moved tweak threshold value to user preferences
This threshold might be needed to be tweaked when working with tables, i.e.
to prevent tap+slight movement be treated as tweak event.
This commit implements basis stuff needed for object tracking,
use case isn't perfect now, interface also should be cleaned a bit.
- Added list of objects to be tracked. Default there's only one object called
"Camera" which is used for solving camera motion. Other objects can be added
and each of them will have it;s own list of tracks. Only one object can be used

Comment from Keir's commit:
Add a new hybrid region tracker for motion tracking to libmv, and
add it as an option (under "Hybrid") in the tracking settings. The
region tracker is a combination of brute force tracking for coarse
alignment, then refinement with the ESM/KLT algorithm already in
libmv that gives excellent subpixel precision (typically 1/50'th
of a pixel)
This also adds a new "brute force" region tracker which does a
brute force search through every pixel position in the destination
for the pattern in the first frame. It leverages SSE if available,
similar to the SAD tracker, to do this quickly. Currently it does
some unnecessary conversions to/from floating point that will get
fixed later.
The hybrid tracker glues the two trackers (brute & ESM) together
to get an overall better tracker. The algorithm is simple:
1. Track from frame 1 to frame 2 with the brute force tracker.
This tries every possible pixel position for the pattern from
frame 1 in frame 2. The position with the smallest
sum-of-absolute-differences is chosen. By definition, this
position is only accurate up to 1 pixel or so.
2. Using the result from 1, initialize a track with ESM. This does
a least-squares fit with subpixel precision.
3. If the ESM shift was more than 2 pixels, report failure.
4. If the ESM track shifted less than 2 pixels, then the track is
good and we're done. The rationale here is that if the
refinement stage shifts more than 1 pixel, then the brute force
result likely found some random position that's not a good fit.

Talked with Brecht and Campbell and they both agreed that bpy.types should match bpy.props
In the ideal world we would rename bpy.props to BooleanProperty. This would break scripts though. So we go for a compromise and at least have some consistency.
*** 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.
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/
Also replace adjust frames integer slider with menu to choose between matching
pattern from keyframe position of from previous frame. think this settings
wouldn't be so confusing now.
This operator does needed changes to
- 3D viewport
- Scene settings
- World settings
- Compositor
- Scene objects
in a way scene becomes ready to be composited into footage.
Known issue: preview doesn't work "out-of-box" after running this script,
selecting View node and hitting Tab helps. Not sure it can be solved
in nicer way at this moment.
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.
- UV's were not being calculated if there were too many VColor layers.
- precalc (omd->size * omd->spatial_size) was being called in a loop.
- use vector functions to avoid pointer indrections on each access which the compiler wont optimize - eg: och->ibufs_disp[f]->rect_float[4*(res_x*j + i) + 1]
- dont call abs() on ints (converts to double and back to int in this case).
also unrelated render buttons change. move saving options directly under the file path since these were easy to confuse with image format options like zbuf, ycc, preview.. etc.
- Fixed incorrect memory access on distoritons more than 128 pixels
- Do not use UNDO operators flags for delete proxy operator (files can't be restored form disk),
and also do not use UNDO for set as background operator (background images are storing in
3d viewport which isn't getting re-loaded on undo which can lead to incorrect users count
of movie clip user).
This should fix an error with generated qtcreator projects.
also replace decoded bytes for unicode escape sequences in the VIEW3D_MT_edit_text_chars menu.
- 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

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.
if a value other than 1/0 was given it would use an uninitialized pointer too (compiler warning, review should pick up this stuff).
also renamed some RNA attrs:
output_name --> output_name_a
output_name2 --> output_name_b
do_output1 --> use_output_a
do_output2 --> use_output_b
do_smudge --> use_smudge
max_velocity --> velocity_max
- 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.
* Changed the user interface for the Ocean modifier, to use less space and look better.
* Changed rna name cachepath to filepath for consistency (fluid cache path also uses "filepath")
* Renamed "Sharp" proximity falloff to "Constant".
* Added a new "Negate Volume" option for "Volume + Proximity" brush.
* Possible fix for random particle clipping errors.
* Code cleanup, changed some splits to row's, much nicer when you only use 2 properties in a row.
* if > elif
* Removed some duplicated code for an if/elif/else check
Did some minor separator() changes too.
to enable from python:
bl_options = {'REGISTER', 'UNDO', 'PRESET'}
from C:
ot->flag= OPTYPE_REGISTER|OPTYPE_UNDO|OPTYPE_PRESET;
- added context member 'active_operator'
- enable this for 'Add Torus' for testing.
