= Mon, August 3, 2015 '''''Week 11 (of 14)''''' =

* Summoned for jury service: Spent entire day at court house in Santa Cruz.
* Dismissed from jury duty but was called to jury box. 

= Tues, August 4, 2015 =

* investigating ways of labelling faces for CLI specification
** looked at: 
*** [[MGED_CMD_E_upper|E]]
*** [[MGED_CMD_e_lower|e]]
*** [[MGED_CMD_ev|ev]]
*** [[MGED_CMD_B|B]]
** none label objects with symbols (only color change, etc. and NOT faces)
** ''ev'' provides some direction
* todo: may have to implement something like ''f_labelvert'' (in mged/overlay.c) but for face index labelling
** OR have users specify verts for face selection (probably not preferable)
* updated design docs reflecting recent integrated patches

non-brlcad expenditures...

* spent time in phone conversation negotiating / considering a job offer

= Wed, August 5, 2015 =

* implementing new mged cmd called ''labelface'' need for kill F
* [https://github.com/behollis/brlcad-svn-rev65072-gsoc2015/commit/cdbe653c24e26fea050289d6f6d9fa220931927f commit #1] added placeholder for lableface mged cmd 
* [https://github.com/behollis/brlcad-svn-rev65072-gsoc2015/commit/db9a7aa52d7d3fc8c8448b99aba2ab9fc7b3aa83 commit #2]  traversing model to collect a list of faces to label. work in progress... 

= Thurs, August 6, 2015 =

* ''labelface'' impl 
** working to get list of faceuses from nmg model
** working to get center coord of face polygons
*** this will allow labels to be displayed at center of faces

non-brlcad expenditures...

* spend much of the day deciding between two employment offers
* chose post-doctoral research over lecturer position

= Fri, August 7, 2015 =

* [https://github.com/behollis/brlcad-svn-rev65072-gsoc2015/commit/35e5931d443219253c223f60e1bcf15a51192723 commit #1]  verified that faceuses are properly gathered in get_face_list. todo: use bu_list instead of array placeholder for faceuse list.
* todo: need to find how to calculate barycenter for face verts (there must be a utility function in brlcad)
* instead: ''very easy as a simple average of coords of face verts''
** where face labels will be placed using ''bn_vlist_3string()'' in ''rt_label_vlist_faces()''

*[https://github.com/behollis/brlcad-svn-rev65072-gsoc2015/commit/9efa36cfadd3e3cc8522f0489c6b4bfcbd3f6224 commit #2] using struct face as replacement to struct faceuse  
* todo: use center of face for face index placement
* since there are two facesuses per face, best to use index of face for label
