Coding period
Week 1
===26/05/2012
Compiled Adaptagrams; studied and ran examples provided for libcola and libavoid.
25/05/2012
- Worked on compiling GOBLIN. However, I get a lot of errors. You can find them here. I am assuming it's because of the c++ standard and their latest update which was made in 2010. Submitted a bug on their sourceforge bug tracker and am waiting for a reply.
- Meanwhile, I'm having a look at Adaptagrams source code.
24/05/2012
Made comparisons between Adaptagrams and GOBLIN.
22/05/2012
Discussed with one of the mentors how to approach the implementation behind the command that would launch the GUI.
Talked about the possible locations where command-line functionality can be developed.
As a first step, looked for proper already existent functions in BRL-CAD that would allow me to ge the directed acyclic graph structure of a tree.
21/05/2012
Read about Adaptagrams library.
Community bonding period
General progress
19/05/2012
Studied some aspects of the GOBLIN graph library.
17/05/2012
Commit access was gained. My first commit was for the src/libbu/test_booleanize.c file; it included style and formatting corrections.
16/05/2012
Patch for the file src/libbu/booleanize.c was accepted and applied in the revision r50566.
15/05/2012
I have modified my first patch, the one meant to create a test_booleanize.c with unit tests for the file src/libbu/booleanize.c. At the same time, I found a small bug in the booleanize.c code. The patch can be found here.
14/05/2012
I have created an alternative patch for the one that is meant to separate out LIBNMG from LIBRT. This one 'moves' the files from the src/primitives/nmg location to src/libnmg without being needed an extra help from someone with commit access.
Here is a link to a temporary location for the patch since it exceeds the size limit provided by Sourceforge.
12/05/2012
I have finished a patch meant to separate out LIBNMG from LIBRT. You can find the patch here. Build system modifications have been made in the following files:
- src/librt/CMakeLists.txt
- src/librt/Makefile.am
and the following 2 files have been correspondingly added for libnmg:
- src/libnmg/CMakeLists.txt
- src/librt/Makefile.am
One thing needs to be made by a person with commit access: move the src/librt/primitives/nmg source code into src/libnmg and apply the provided patch.
Reminder: there's also this patch that I've made and needs to be reviewed. It contains unit tests for the src/libbu/booleanize.c file and it fixes a small bug that wouldn't have passed one of the tests.
10/05/2012
I've studied the src/mged, src/librt and src/conv folders, looking for methods that can be used to access the elements of a CSG tree.
Methods that got my attention:
- in the src/librt/db_tree.c file:
int db_tree_list(struct bu_vls *vls, const union tree *tp)
which fills a bu_vls with a representation of a given tree appropriate for processing by Tcl scripts. Could be useful in constructing the interactive graph.
union tree *db_tree_parse(struct bu_vls *vls, const char *str, struct resource *resp)
which takes a TCL-style string description of a binary tree, as produced * by db_tree_list(), and reconstruct the in-memory form of that tree. Could be useful after the structure of the graph is modified and the CSG needs to be updated.
2. Get commit access
08/05/2012
Worked on the patch for the NMG migration task (create a separate library LIBNMG outside LIBRT). This time, because BRL-CAD previously built without errors, things go smoother.
1. Compile & install BRL-CAD
28/04/2012
After discussing my problem with one of the mentors and finding the cause for these errors, BRL-CAD completely built.
27/04/2012
I created my first patch for BRL-CAD by using the virtual machine disk image so now I want to compile and install BRL-CAD from source (from a svn checkout).
I've followed the instructions with respect to the dependencies (the ones from here http://brlcad.org/wiki/Compiling and from the doc/README.Linux). I've used the command
cmake -DCMAKE_BUILD_TYPE=Debug -DBRLCAD_BUNDLED_LIBS=Bundled .
but after using
make
, I kept getting these errors http://pastebin.mozilla.org/1602696.
Afterwards, I decided to try the command
cmake -DCMAKE_BUILD_TYPE=Debug .
but then I encountered another error while running it: http://pastebin.mozilla.org/1602697. I managed to solve the problem by installing itk3 and itk3-dev. However, while running the make command I bumped into the previously mentioned make errors and this one: http://pastebin.mozilla.org/1602700. The first ones refer to fontconfig symbols.
