Wed, July 1, 2015: Week 6 (of 14)

• commit #1: filling out vertex info with structures to avoid errors with incomplete data structures
• getting crash in nmg_mvu on line 365: BU_LIST_APPEND(...); need to investigate.
• use case for above: 'make modelname nmg', then 'nmg cmface modelname coords'
• rechecked patch https://sourceforge.net/p/brlcad/patches/387/
• verified by compiling with STRICT enabled. posted build.log to sourceforge.
• problems with compilation apparently not associated with changes. builds fine with STRICT disabled.

• Appointment with retinal specialist from 9:30am to Noon PST.
• Not be able to work today due to pupil dilation.

Fri, July 3, 2015

• Midterm summary located at link
• still investigating nmg_mvu issue for ged_nmg_cmface subcommand:
  • likely that the vertexuse is being improperly treated for loop creation.
  • should there be a vertexuse present in the model for the new loop (prior to nmg_mvu call from nmg_cmface)??

Mon, July 6, 2015: Start of Week 7 (of 14)

• commit #1 fixed issue with missing bu_list in vertex struct
  • while commit #1 provides a "working" call to nmg_cface with three verts, the face is not visible in the render window??
  • ged_nmg_cface appears to make the proper calls...
  • once problem is found with rendered model, need to extend for n verts (should be trivial)
• commit #2 attempt to fix issue with ged_nmg_cmface crash in nmg_info/nmg_findeu(); in loop

Tues, July 7, 2015

• received good direction from brlcad in irc
  • reviewed http://www.google-melange.com/gci/task/view/google/gci2014/5546966268248064
  • reviewed http://brlcad.org/wiki/NMG
  • previously unaware that nmg models could be created with ged_put
• todo: need to plan high-level subcommands after cmface working
• todo: check winding order in cmface, as http://brlcad.org/wiki/NMG mentions potential crashing with incorrect winding order

non-brlcad time expenditures...

• spent some time applying for positions

Wed, July 8, 2015

• investigated put / get database commands.
  • should illuminate sequence of calls needed by subcommands for nmg api calls
  • posted related questions in irc
• todo: use info from above to fix mged calls implemented in libged/ged_nmg_cmface.c
• commit #1: null commit to synchronize to github from nonlocal repos

non-brlcad time expenditures...

• oil changed for car; 3 hour wait!
• wrote essay, etc. for instructor position application

Thurs, July 9, 2015

• investigated get / put nmg object creation...
  • need to follow the code from this sequence of calls using 'put' CLI:
    • ged_put()
    • rt_nmg_make()
    • rt_nmg_adjust()
  • above sequence of calls creates an nmg object and adds verts / faces
• todo: revamp *ged_cmface* using preceding process.
• note: apparently using nmgmodel.c was not the best example of manifold nmg object creation!
• todo: once ged_cmface() properly impl and submitted as patch, can move on the spec for high-level subcommand list; perhaps vert / face removal subcommand CLI routines are the easy to start with??

non-brlcad time expenditures...

• VDA 2016 template and reformat of paper for submission
• 10 job applications submitted

Fri, July 10, 2015

• commit #1 using method from rt_nmg_adjust. still some issues with calls to nmg_cmface. soon to be resolved.
• appears that vert structs are not being filled out correctly and thus crash in cmface; need to test with known "working" args

non-brlcad time expenditures...

• applications
• car in garage again for brake pads
• car will be in garage again next week for air bag recall (ford mustang)

Mon, July 13, 2015: Start of Week 8 (of 14)

• commit #1 cmface now working. using rt_nmg_adjust as model for impl.
• commit #2 added variable number of verts for CLI.
• commit #3 check for minimum number of verts for manifold face
• cmface patch 390 submitted

Tues, July 14, 2015

• mm (make nmg object model) subcommand patch 391 submitted
• updated patch 390 with build fix and code cleanup
• commit #1 cleaned up loop var. removed unused fastf_t declaration
• found potential build problems when BRLCAD_ENABLE_STRICT=YES. noted in patch 390 reply (opennurbs lib)
• todo:
  • impl face kill routine as subcommand
  • design remaining subcommands (will be higher-level than internal nmg api)
  • post usage instructions for simple box creation use case using subcommand 'cmface'
  • will need to determine which routines that have been submitted in patch 354 that need to be removed
