[Soc-2012-dev] GSOC 2012 Texture/UV tools development week 12 report

[Antony Riakiotakis]

What you did this week:
=====================
* Improved Djikstra algorithm for isomap
* Investigated geodesic distance calculation algorithms
* Managed to put two of them into Isomap unwrapping. The second one finally
gives a correctish result. However, it doesn't look better than ABF. I
think the reason is that the quality of the algorithm relies heavily on the
quality of the calculated distance. Since the current algorithm is an
approximation, we get errors that are cumulative with distance and the
algorithm relies on a few assumptions about the mesh that do not always
hold.

TODOS
==========
Wrap up todos:

* bugs with maintain image on seams/boundary edges
* add support for texture angle in 2d texture painting
* fix view mapped overlay of brushes
* Add Mask texture access from properties panel.
* Do docs/video of features.

Especially for texture paint I have a proposal in mind to unify brush and
tool code in a better way since I regard the current implementation of my
features more of a patchwork than a product of good design. Especially the
way 2D painting code is mixed with 3D painting code and the way various
tools and paint modes are being handled at different places is quite
obfuscating.
