From BlenderWiki

What I did this week:

• Add keyframe selection in multi-view mode. With keyframe selection and witness camera support, the re-projection error can be as low as 0.3 pixels for the tested video clips. Although re-projection error is not a authentic metric for reconstruction accuracy, it sort of shows the performance of the solver.

• Add new color theme for linked tracks and selected linked tracks. If tracks across clips get linked, they are shown in a different color from normal tracks.

• Discuss the correspondence UI issue with my mentor. We are agreed on making a separate mode for specifying correspondences across clips. Potential benefits of this independent mode in space clip includes: (quoted from Sergey)

- remove hacks of searching for another clip across the whole window 
- you can show only options and buttons which are relevant to correspondence mode (link/unlink tracks) 
- you can visualize with a parenting line what track corresponds to what
- for both clips you'll know where to get list correspondences from

• Work on the UI icon stuff and reading docs about adding icon. Add a new icon for correspondence mode.

• Start the UI work of multi-view reconstruction. It is focused no the correspondence mode in space clip.

What I will do next week:

• The primary goal for the next few weeks is to make a decent UI for correspondence and multi-view reconstruction. I will start by drawing a double-clip view side by side in movie clip editor. The correspondence mode will be simple and solely focused for specifying correspondences.

• A secondary goal is to gather bug reports and user experience from artists about the multi-view solver. So a series of bug fixes and improvements will be done in parallel.
