Development Logs[edit]

Community Bonding Period[edit]

Due to my semester end exams (Apr 26 - May 17), my time spent during community bonding period was less but I still managed to do the following:

  • Week 1
    • Prepared a flowchart to understand how the execution of the rtcheck program works : rtcheck_flow
    • Was introduced to 'gdb' which helped me a lot to analyze the flow.
    • Understood how the front-end portions of rt and back-end portions are connected by linking the view*.c files
  • Week 2
    • Read the documentation to understand the RTUIF API : https://brlcad.org/wiki/Developing_applications
    • Understood the origins of libanalyze functions.
    • Discussed some ideas on how to implement the libanalyze function, all were bad ideas because they all involved calling the rtcheck program using execvp() as they usually end with exit().
    • Was suggested a basic plan on how to proceed.
    • Understood how libanalyze functions were used by an example : libged/voxelize.c and libanalyze/voxels.c
  • Week 3
    • Complied a version of the rtcheck program by just copying the relevant files to libanalyze/overlaps/.
    • Discussed the plan related to rtcheck in detail.
    • Understood the concept of using contexts and callback functions.
    • Tried out callback functions, implementing a basic callback function that alters an int.

Coding Period[edit]

Week 1[edit]
  • 14/05/18
    • trying to build a new rtcheck command by stripping down the non-necessary parts of the front-end, so that the code is easier to understand.
    • discussed a lot of issues with mentor.
  • 15/05/18
    • started working on the design of the libanalyze function
    • all parts of rt/main.c and do_ae() done
  • 16/05/18
    • added do_frame(), do_run() and grid_setup() to libanalyze.
  • 17/05/18
    • added worker() and do_pixel()
    • used a worker_context to pass data to worker using the void pointer for bu_parallel
    • when I ran the command I was getting segfault at rt_gettrees, thought I'd fix it next day
  • 18/05/18
    • figured out the problem but it meant moving a lot of content to libanalyze
    • I did it anyway out of curiosity and it fixed the problem with rt_gettrees still it crashed at rt_shootray!
    • At the end of the day after a lot of debugging and trials, found out that rt_shootray was calling the hit sequence of gqa :O, not sure why.
    • A quick rename of the hit sequence of libanalyze to check_hit solved the problem.
    • Still need to figure out how to call rt_gettrees without moving all function calls to libanalyze.
  • 19/05/18
    • Added code to fill the overlap list passed through callback data.
    • Using `gedp->ged_wdbp->dbip` to get the db name instead of asking it before objects.
  • 20/05/18
    • Fixed printing of the overlap list.
Week 2[edit]
  • 21/05/18
    • Clean-up of the libanalyze function :
      • Fixed a derp with setting default values of width and height in libanalyze instead of libged.
      • Removed redundant header files.
    • Read code for libged/gqa.c
    • Prepare patch for the work done in first week.
  • 22/05/18
    • Submitted the patch:#488
    • Did follow up and submitted v2.
  • 23/05/18
    • Didn't do much today : Read the checker.tcl file for understanding.
  • 24/05/18
    • Updated the patch and submitted v3.
  • 25/05/18
    • Discussed the plans for refactoring rtcheck.
    • Started work on rtcheck.
  • 26/05/18
    • Added plot file output option.
    • Fixed check_overlaps command not showing up in Archer.
    • Submitted patch #491 fixing some minor issues with the accepted patch #488.
  • 27/05/18
    • Added old_way of processing stdin.
    • Added command driven way of processing stdin.
    • Have to test the changes, it compiles fine.
Week 3[edit]
  • 28/05/18
    • Couldn't code in the morning hours. My cousin brother came and played games on my PC all day!
    • Added getting objects from view feature to ged_check_overlaps
    • Tested rtcheck executable for matflag inputs.
  • 29/05/18
    • Trying my best to get the display of overlaps working for ged_check_overlaps.
    • Okay it worked but I used temp file so that I could use two inbuilt functions pdv_3line and rt_process_uplot_value. But using them is not needed. So as suggested by Daniel, I will try to merge them together and remove the file dependency and buildup the list in my overlapsHandler.
    • With it I found one more bug with yesterday's work, that if do draw g4 and do checkover_laps g4 then it would consider g4 twice! :/. To solve this Daniel suggested to not consider visible objects if objects are mentioned with command.
    • Success! all worked out with so much minimal code, just 5 lines instead of my initial work that involved 25 lines.
  • 30/05/18
    • Fixed bug with overlays considered as visible object on second run.
    • while testing matflag for rtcheck:
      • fixed a bug in tree command.
      • added parsing of az/el in degree/radians values for cm_ae.
      • fixed issue with Multiview giving segfault.
    • Added -r, -R flag to rtcheck.
    • Added -d flag to rtcheck and check_overlaps to print some debug information.
  • 31/05/18
    • Fixed a major flaw in the overlapsHandler giving the same data for both reg1 and reg2.

    • Added feature to check_overlaps for getting view information from gedp.
  • 1/06/18
    • Fixed scrambled overlays from check_overlaps.
    • Experimenting with bu_list for overlaps list.
  • 2/06/18
    • Using bu_list for overlaps_list in rtcheck
    • Didn't do much other than that, spent some time with family :)
  • 3/06/18
    • Submitted v2 patch for check_overlaps changes #491
    • Fixed bug with multiview caused by handling overlapList in main, moving to do_frame solved it.
