Development Logs

Community Bonding Period

• Forked github repo and compiled working version of BRL-CAD
• Made the pages for project plan and dev logs
• Ideated various ways to implement undo and set constraints

Weekly update - Coding Period

• Week - 1
  • Day 1-2
    • Working version of undo command implemented in mged which prints name of database when command is given.
    • Understood how commands use wrapper functions and function of cmd_ged_plain_wrapper()
    • Set flags -n and -h aimed to execute multiple undos and show usage respectively
    • Understood how hidden objects work, have to explore temporary file alternative to save backup objects
    • Stuck, trying to iterate over all objects in database but not finding the right function
    • Finally found way to iterate over all objects from move_all.c
    • Converted undo.c to undo.cpp so that code can be more functional
  • Day 3-4
    • Had a discussion with my mentor how to proceed further on the undo
    • Data accesible over all processes stored in _GLOBAL as name, value pairs
    • Name of the last added object and last killed object stored in _GLOBAL
    • Wrappers of make and kill modified to add the labels
    • Introduced 3 variables in undo.cpp to keep track of latest_change and then take necessary action to undo
