Report Week 6[edit]

The cmake errors has solved by adding UNKNOWN and IMPORTED files in cmake files.
I have added dm-qt.c in libdm and mged, dm-qt.h in include. dm-qt.c in libdm contains the empty functions for the display manager. The dm-qt.c file in mged connects the display manager with mged. In CMakeLists.txt (root/libdm/mged) I have added a option for qt and included the added files for compiling. In dm.h, dm-generic.c and attach.c i have added macros for dm-qt. BRL-CAD will compile with Strict=off.

Now it is possible to attach a new dm with the command:

attach qt

After attaching a qt window I have gotten a memory leak. Through implementing the Qm_dm_init() function the problem get solved and attaching will cause no error and nothing happens.

Report Week 5[edit]

I have used the functions in dm_X.c and deleted all function bodies and renamed them to qt_function. In dm-generic.c I have changed X_open to qt_open for testing. I have to implement a cmake macro for qt, add it to dm-generic.c and remove X_ changes.

After that I have tried to built BRLCAD. Through Warnings I couldn't compile it. So I have changed to Un-Strict Mode in cmake and successfully compiled libdm.

In the next step I have tried to link Qt with BRLCAD. After I added only find_package in CMakeLists.txt I have gotten following error:

I have tested many approaches for the Display Manager and tried to change the default Qt Application structure to encapsulate it in the qt_open() function. So every Qt display manager will work as a own application.

The main goal is to get a working structure of the C++ Display Manager Class with the dm Structure in "dm.h".

Report Week 3[edit]

I started with the structure of the Qt Display Manager. I have realized, that it is not possible to use the OO approach directly. The function pointers in the structure "dm" can't be used for pointing on member functions (methods).
So I decided to encapsulate a drawing class and instantiate it as a global variable in the qt_dm.cpp. The functions are used as interfaces to this class.

Report Week 2[edit]

I have built BRL-CAD successfully on Linux and Windows.

I have released two Patches in this week:

- Refactor and manage libbn tolerance uses by providing an interface default (e.g., an init macro) and making everyone use that where it is hardcoded to 0.0005 presently.

-I have added a relative float check (following to: and fixed some FIXME section with it. I am not certain about it. If the algorithm is suitable for brlcad, i could change the rest of vmath.h.

On both I am waiting for Feedback.

Report Week 1[edit]

I have built BRL-CAD from svn on ubuntu (12.04).
I have installed and built all depencies on Windows, but I get following build errors (only a few of them, the errors repeating):
