[Soc-2006-dev] SoC weekly reporting

[Nicholas Bishop]

a) This week:
This week I've focuses almost entirely on the painting system for
retopo. It now has automatic face generation and a paint mode. The
paint mode adds a whole new level to the tool; it currently has a pen
tool and an ellipse tool, with a line tool in progress.

b) Next week:
Not too many next weeks left, unfortunately, but I feel pretty
comfortable with the overall progress of the project. One thing I'd
like to get nailed down is a persistent bug that usually only shows up
under Windows, which makes it difficult for me to find. The bug seems
to involve uninitialized memory, and it seems to be triggered by undo.
Fixing this bug would fix quite a lot of bizarre problems that some
users are experiencing.

Other than that bug, I plan to continue working on the retopo paint
mode; I hope to have it fairly stable within a couple more days.
