=== PROJECT SUMMARY ===
 
 
This year's GSoC was my first and most exciting projects given the fact that I'm working on my first opensource project and contributing for my first time to a great software and organization like BRL-CAD.
 
 
For the past three months I worked on implementing a pull routine which reversed the effects of a push on a CSG tree. This project focused on reversing the effects of the push command available in BRL-CAD and also pulling up and unpushed node. While following my implementation outline as described in my [http://brlcad.org/wiki/User:NyahCh3ck20/GSOC13/Design_Document Design Document], I kept modifying the plan as needed and tried updating my [http://brlcad.org/wiki/User:NyahCh3ck20/GSoc2013/Coding_Report logs] daily especially when I initially had no stable Internet access.
 
 
Before the Mid-term Evaluations, I studied the push and xpush routines seeing how the matrices were pushed down the tree in respective commands and started implementing and finished implementing the pull_comb() routine which pulls the matrix transformations in a combination node. Submitted patches on sourceforge for review. I tested various parts of the routine and made sure routine works perfectly will continue testing and fixing bugs if any post GSoC to make sure command is complete. Also, I wrote tests for the poly.c routines and submitted patches on sourceforge; tested the bn_mat_inverse() routine implemented for BRL-CAD and proposed new routine  which are still awaiting review by mentors.
 
 
Post Mid-term evaluations, I studied the various primitives trying to figure out how to implement the pull_leaf() routine for each primitive which was later disproved by Sean as a bad design choice which led to my implementing of the pull_leaf() using the AABB's of primitives which enabled me to pull translation components successfully. I also developed the pull interface, wrote regression tests, created the man pages and other documentation which will integrate command fully into BRL-CAD.
 
 
During Final Days and Post-GSoC I plan to finish implementing the pull_leaf routine which pulls both the scale and rotation components of primitives for BRL-CAD completing the pull routine and any other new projects as needed.
 
 
This was one of the most exciting summers of my life.
 
 
Cheers!

== Sept 16 - Sept 22  ==
  
Monday Sept 16,
 
 
*Started re-testing the pull routine starting from the pull_leaf which pulled correctly.
 
 
*Discovered a bug with the pull_comb() routine which pulls matrices which are not symmetric;so will fix bug tomorrow.
 
 
*Started stubbing pull to archer but had an error will try to fix problem tomorrow or post question on mailing list and see what comes up.
 
 
 
Tuesday Sept 17
 
 
*Continued testing the pull_leaf and realised NAN values were being pulled from the primitives which are to be set to zero in such cases.
 
 
*Started fixing bug.
 
 
Wednesday Sept 18
 
 
* Continued fixing pull_leaf routine but realised pull_comb() routine pulled matrix transformations having NAN as values. to ask mentors about this problem if it persists.
 
 
* Was in a meeting with the Vice Chancellor as Google Student Ambassador and explained my Vision for the University during my tenure.
 
 
Thursday Sept 19
 
* Started preparing for my upcoming exams next week; and had a meeting with the Public relations Officer of the University concerning my recent appointment as Google Student Ambassador and plans for the University community.
 
 
 
Friday Sept 20
 
* Attended the Interview at the University Media House( Chariot FM) where I explained my GSoC experience and current work as Google Student Ambassador.
 
 
Saturday Sept 21
 
*Wrote the Project summary and continued preparing for my exams next week.

#Monday Sept 23
 
 
Started looking at the BRL-CAD documentation spreadsheet posted by Harmanpreet and summarising all documents on the list. Requested for the script from Harmanpreet that automates the summary of the documents.
 
 
@Will finish summarising documents tomorrow; since I have to prepare for some of my exams coming up from tomorrow.
