[Soc-2013-dev] Weekly Report #5 Mesh Sketch Editing

[Alexander Pinzon Fernandez]

Hi All

Week 7 (jul 15 - jul 21)
Report[edit<http://wiki.blender.org/index.php?title=User:Apinzonf/Gsoc2013/progress&action=edit&section=27>
]What I did this week?

This week I've fixed some problems of the tool:

   - Previously used two contexts SuperLU, Now only used a context of
   SuperLU.
   - The system factorizes the Laplacian matrix only one time, so when you
   modify the vertices only need to calculate the solution without the need to
   factor again.
   - I remove the computation of implicit rotations because not improve the
   solution.
   - I eliminate the use of the library Eigen3 in my system because SuperLU
   library has better performance.


I built one in windows version to download and test.

   - This is a test version has some bugs and console displays debug
   messages.
   - This is a work in progress and the next version will use the grease
   pencil.
   - This system works with meshes composed of triangles or quads. (It is
   not a trivial task, and academic papers solve it only in mesh with
   triangles).
   - The user interface is not finished.
   - I wrote page on the Wiki, on that page explains how to use the tool.

I publish this page in http://www.blenderartists.org/, so that people begin
to test and review

I made a video showing what can be done now with the application at this
time

]What you plan to do next week?

I will analyze the comments received on the website of BlenderArtist, to
propose a design for user interaction.

I will continue investigating the problems with the system when the meshes
are dense.

]Any roadblocks, difficulties, etc.

I have had many problems with the size of the edges and floating point, I'm
still researching how to improve it.
