[Soc-2014-dev] Weekly Report #4: NURBS Modernization

[Jonathan deWerd]

This week's progress:
- About 75% of the way to the trimming code for the UGC tessellator.
-- Details: http://wiki.blender.org/index.php/User:Jjoonathan/Trim_Algorithms
-- Code: https://github.com/jjoonathan/PolyTest/tree/master/PolyTest
- Not sure how I should write up my midterm proposal, but I stated my intention on the wiki page to put up a gallery of imported 3dm files. I anticipate being able to show at least one from an interested artist, a handful from grabcad.com, and a few of my own that really show off trimming (I've gone through the lynda.com tutorials for the corresponding parts of Rhino)

What I want to have done by next friday:
- Finish the trimming code
- Put the UGC+trimming code in blender
- Demos for the midterm to show it off

>> - I can successfully load order 2, 3, and 4 NURBS curves! To be clear: no surfaces yet and I haven't added support for a bunch of .3dm features, from small ones (not-open curves with irregular knots) to big ones (trimming). But I'm not held up on these, I'm hung up on...
>> - Integrating opennurbs into cmake. I got my first result by manually tweaking the Xcode files that came out of cmake but this is no good in general. I've put opennurbs in the "extern" folder and I'm still working out how to persuade cmake to generate the appropriate build files.
>> - Got a stakeholder .3dm testfile. It's not production data but it tests for a specific cut that was needed in production. I have lots of .3dms now: I have 3dms that I made, 3dms from stakeholders, and lots of 3dms from the Rhino example libraries.
