Hello Raweiss99,
Thank You for accepting my proposal.
I want to discuss some points about my project with you.
1. I have brlcad-7.20.2 installed in my computer. And Installation
directory is /usr/brlcad/
2. As I couldn't completed my patch earlier before results, I have worked
on a trial patch. Attached file is the C Program for patch.
What I did is the following :-
a.) I checked brlcad/usr/libbu/ directory. Selected function bu_image_save
for testing from image.c.
b.) Using below command I confirmed that image.c has been compiled.
$ nm -D /usr/brlcad/lib/*.so | grep bu_image_save
c.) Later I set the LD_LIBRARY_PATH variable.
d.) Now I compiled test file using command given below
$ gcc -I /usr/brlcad/include/ test.c -L /usr/brlcad/lib -lbu
3. As the output of the program, I was able to write a png image. I had an
array of size 400 which I had initialized to zeros. I create a png image
of size 20x20. Now, this program generates a black 20x20 image.
4. I would like to work on following tasks before 21st may :-
a.) I want to try some more functions for test patch and compile manually
with method described above. Later I would try corresponding
CMakeListes.txt build file.
b.) I will work on compiling and running BRL-CAD. I will work on being
familiar with basics of subversion.
c.) I will be working on small succinct patches to engender trust with
existing developers. So that I can start coding at right time.
d.) And I will follow some other steps from
http://brlcad.org/wiki/Summer_of_Code/Checklist.
5. I want to know, on what kind of design documents I will have to work on
before coding.
6. As I described in my proposal I have my end-semester examination until
May 6. So I'll be little busy in this duration. I hope you will understand.
After this I assure you to be available as promised in my proposal.
7. If you have any suggestion or want share any Linux command (or link)
useful for this project, please share I would be delighted.
8. Once Again Thank You very much. I'm really grateful for your trust.
regards
