From BlenderWiki

First of all, this week I didn't write much code (failed to finish [2, #4] - see "Tasks").

As my project involves porting Wings3D's tesselator to Blender [1], this week I learned about BMesh's and Blender's architecture, Erlang language, and Wings3D. You can check out my notes on those subjects [2]. I'm currently trying to understand their tesselator [4, #4] and make my code snippets [2, #4] work properly.

For the next week I plan to expand my notes [0*, #5], wrap up the functionality of wings_tesselation [1, #5], and write my first patches [1.1, 2, #5].

You can always be up to date with what I'm doing by checking my wiki page, I try to update it frequently.

Trivia: From skimming through ba.org posts I understood that artists (i) like Wings3D's tesselator better and (ii) they'd like a better way to turn ngons to quads.

Tasks for this week (#4):

1. read BMesh, Blender doc
2. (not finished) coding tasks [3]
3. familiarize with Erlang
4. familiarize with Wings 3D tessellation

Tasks for the next week (#5):

1. • expand notes [2]
2. finish my notes about what wings_tesselation [4] does (and how)
   1. start implementing the new scanfill based on that
3. make a prototype for tri/quad-angulation [2, week 4]
   1. • start coding the recursive optimal-ngon-partitioning (ngon poke tool - 3rd method, in my proposal [1])
