[Soc-2011-dev] weekly progress report #7 - 4th-10th July

[Sergey I. Sharybin]

Hi, Blender Community!

I'm still wirking on camera tracking integration project 
(soc-2011-tomato branch) and here's some small progress for this week
> 1) what you did this week
(big changes only)
- Fixed bug with swapped width/height used for per-pixel cycle when 
disabling color channel to be used for tracking.
- Marker preview is now using sub-pixel precision.
- Tracking stuff uses the same imbug generation function as preview area 
does. Sub-pixel precision should be ok now here too.
- Request from Keir: add command line argument to toggle logging stuff on.
- When libmv fails to track marker for next frame, add marker for new 
frame with old position and set it up as Disabled.
- Improvenments in track path displaying
- Update Properties Editor for SpaceClip during playback.
- Added ActiveClip property to the scene.
- Initial implementation of 3d reconstruction.
- Added constraint "Camera Solver".
- Added "reference" property to "Follow Track" constraint. Now object 
could be "parented" to 2D track position or to 3D bundle position.
- Implemented "Set Origin" operator.
- Added "Specials" W-key menu for SpaceClip.
- Blender's camera affects on reconstructed data.

> 2) what you will do next week
- Improving reconstruction workflow:
   * Easier scene orientation.
   * Camera settings presets.
   * Deeper investigation of sensor size patch from tracker 
(http://projects.blender.org/tracker/?func=detail&aid=24427&group_id=9&atid=127)
   * Some elements could be re-exposed better into ui. I.e. focal length 
in pixels isn't useful. Better to add "chooser" of units.
- Implement such things as displaying bundles near the tracks which 
could help to control if reconstruction was accurate.
- Bug fixing, bunch of improvenments based on artists feedback and so 
and so..
> 3) any problems that will require extra attention and the impact on
> your proposed schedule
Still can't continue workingon proxies integration.But it's not really 
stopper yet.
