49bc310671 Move guarded objetc allocation to a guardedalloc header
Also made libmv-capi use guarded objetc allocation.
Run into some suspecious cases when it was not so
clear whether memory is being freed or not.

Now we'll know for sure whether there're leaks or not :)

Having this macros in a guardedalloc header helps
using them in other areas (for now it's OCIO and libmv,
but in the future it'll be more places).

32faec1a53 Remplace bunch of annoying ifdefs in tracking.c with a libmv-capi_stub.cc
Makes code in tracking.cc much easier to understand and modify,
without worring to breck compulation with Libmv disabled.

It is still possible compilation will break due to libmv-capi
changes, but that's not happening so much often.

is copying properly to our sources.

b7af3207cc Bye-bye, SSBA!
With new bundle adjustment based on Ceres we don't need
SSBA library anymore. This also means we don't need ldl
library and libmv is no longer depends on colamd as well.

4cf9034f6d Remove extern_ssba workaround
SSBA seemed to be working OK last time i've checked it
with MSVC and optimization enabled.

Also, we'll likely replace it with own BA soon, which
works fine with MSVC anyway.

ea99b9a392 Made ldl code a part of extern_ssba library, otherwise gcc fails to
find ldl symbols because order of libraries seems to be critical
for gcc linker.

A bit stupid, but that's how linker works..

Both CMake and SCons shall work fine on linux now.

1f88ee6213 Fix #34299: Motion Tracking 20x slower under Windows
Root of the issue goes to SSBA library which didn't work
properly when using optimization in MSVC. It was worked
around by disabling optimization for libmv, which is in
fact shame and shouldn't have been done.

It seems after some changes optimization does not affect
on SSBA code, but enabling optimization could be risky so
close to release.

For now solved by splitting SSBA to separate CMake/SCons
library, disabling optimization only for this particular
library and enabling optimization for rest of libmv.

Tested on all files which used to fail with optimization
enabled in SSBA and all of them works the same as before.
Tracking speed is significantly higher now.

After release we'll enable optimization for SSBA as well,
so there'll be no crappy build setup. Later we'll replace
old SSBA library with new BA code based on Ceres.

Bundle script would be broken for until then, so better
not to use it.

59ef51aa27 Initial Ceres integration into Blender
Currently only put sources of Ceres library into extern/libmv/third_party and
setup CMake and SCons building systems.

Integration details:

- Even CMake build files are not re-used from Ceres's trunk: they're using some
  automatic stuff detection like glog, pthreads, protobuf and so and it's not
  so clear how to re-use that files without modifications.
  And IMO it's easier if build files are getting re-generated automatically to
  match Blender-specific setup rather than keeping changes made locally in
  Blender in sync when re-bundling Ceres library. Especially in case when it's
  already needed to support SCons build system.
- Integrated only actual sources, all tests were stripped. Probably it'll be nice
  to have them, but they'll need clear integration with current module test stuff
  in Blender.
- Suitesparse was disabled. It'll help a lot having it, but there are some difficulties
  making cholmod working fine on windows. Would be added in future
- collections_port.cc was also stripped. It's not used by Ceres's upstream and
  it gives compilation error (undefined uint32 -- looks like namespace issue).
- Currently all schur eliminators are included. Not sure if it makes sense,
  also not sure if it makes sense having them switchable on and off -- IMO better
  to have single configuration which works and does not require special tweaks
  after everything was set up.

To bundle updated version of Ceres:
- Go to extern/libmv/third_party/ceres folder
- Run ./bundle.sh

This will checkout fresh Ceres snapshot of Windows branch (which is currently
most interesting from integration into Blender POV), apply all patches listed
in patches/series and copy needed files into Blender's working copy. This will
also re-generate CMake/SCons build rules.

If you'll need extra files from Ceres repository which are not present in
Blender, you'll need to copy them manually and then run ./mkfiles.sh from
extern/libmv/third_party/ceres folder which will update list of files used
by Blender.

Thanks to Leir Mierle and Sameer Agarwal (and all others who helped developing
Ceres) this library and thanks to Keir Mierle with help integrating it into Blender!

ae06ebcd95 Hopefully compilation with MinGW will work again.
Tested with official MinGW and SCons, not sure how ti check it when using CMake.

27d42c63d9 Camera tracking integration
===========================

Commiting camera tracking integration gsoc project into trunk.

This commit includes:

- Bundled version of libmv library (with some changes against official repo,
  re-sync with libmv repo a bit later)
- New datatype ID called MovieClip which is optimized to work with movie
  clips (both of movie files and image sequences) and doing camera/motion
  tracking operations.
- New editor called Clip Editor which is currently used for motion/tracking
  stuff only, but which can be easily extended to work with masks too.

  This editor supports:
  * Loading movie files/image sequences
  * Build proxies with different size for loaded movie clip, also supports
    building undistorted proxies to increase speed of playback in
    undistorted mode.
  * Manual lens distortion mode calibration using grid and grease pencil
  * Supervised 2D tracking using two different algorithms KLT and SAD.
  * Basic algorithm for feature detection
  * Camera motion solving. scene orientation

- New constraints to "link" scene objects with solved motions from clip:

  * Follow Track (make object follow 2D motion of track with given name
    or parent object to reconstructed 3D position of track)
  * Camera Solver to make camera moving in the same way as reconstructed camera

This commit NOT includes changes from tomato branch:

- New nodes (they'll be commited as separated patch)
- Automatic image offset guessing for image input node and image editor
  (need to do more tests and gather more feedback)
- Code cleanup in libmv-capi. It's not so critical cleanup, just increasing
  readability and understanadability of code. Better to make this chaneg when
  Keir will finish his current patch.

More details about this project can be found on this page:
    http://wiki.blender.org/index.php/User:Nazg-gul/GSoC-2011

Further development of small features would be done in trunk, bigger/experimental
features would first be implemented in tomato branch.
