  • 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:
    • 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
  • commit #1 added placeholder for lableface mged cmd
  • 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

  • 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()

  • commit #1 able to label faceuses at min pt of their bounding box. faceuse index used for label. todo: need to plot label at center of face. also need to find way to show both front / back facing faceuses. right now they are overdrawn. placeholder array causes seg fault when dereferencing empty faceuses in array.
  • 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
  • see:

/**
 * Note: there will always be exactly two faceuse's using a face.  To
 * find them, go up fu_p for one, then across fumate_p to other.
 */
struct face {
    struct bu_list l;		/**< @brief faces in face_g's f_hd list */
    struct faceuse *fu_p;	/**< @brief Ptr up to one use of this face */
    union {
	uint32_t *magic_p;
	struct face_g_plane *plane_p;
	struct face_g_snurb *snurb_p;
    } g;			/**< @brief geometry */
    int flip;			/**< @brief !0 ==> flip normal of fg */
    /* These might be better stored in a face_a (not faceuse_a!) */
    /* These are not stored on disk */
    point_t min_pt;		/**< @brief minimums of bounding box */
    point_t max_pt;		/**< @brief maximums of bounding box */
    long index;			/**< @brief struct # in this model */
};

  • commit #1 now taking avg of min and max bounding extents. works great for label placement.
  • commit #2 rt_label_vlist_faces caught in infinite loop. face list element had forw / back points to itself. todo: fix.

Wed, August 12, 2015

  • added labelface documentation
  • added patch 403 for labelface cmd
  • commit #1 fixed problem with adding same face struct to bu_list - which caused self-referential node (forw/back pointers pointing to node itself) in list
  • commit #2 added help lookup for 'lableface'
  • commit #3 removed accidental redundant error checking
  • todo: implement 'kill F' next, using the indices provided in display by labelface
