| |
− |
| |
− | ==Week 4==
| |
− | *Weekly milestone:
| |
− | **Have content displayed in the window
| |
− | *9 June:
| |
− | **Solved a issue regarding the cmake build - I forgot to add Qt_INCLUDE_DIRS.
| |
− | **Created a custom window so that it can be easily added content to it.
| |
− | *10 June:
| |
− | **Released memory so that the qt_close function is done.
| |
− | **Started working at content displaying. Since this is the main aspect I want to do as much research as possible on how to represent the backing store and how to display its content.
| |
− | *11 June:
| |
− | **Break day.
| |
− | *12 June:
| |
− | **Created and allocated the backing store for the framebuffer.
| |
− | **Started working at the write function.
| |
− | **Managed to get some content displayed - even though it's far from done, it is a good start

− | **Mostly a break day.
| |
− |
| |
− | ==Week 5==
| |
− | *Weekly milestone:
| |
− | **Finish the write function.
| |
− | *16 June:
| |
− | **Finished a first version of the write function. Also, tested if more complex models are displayed correctly.

| |
− | *17 June:
| |
− | **Started working at the open_existing function.
| |
− | *18 June:
| |
− | **Break day.
| |
− | *19 June:
| |
− | **Searched for the best way on how to create the open_existing function. Since until now, the functions were declared in fb.h and all framebuffers use the same header, after adding the Qt includes a lot of conflicts appear so a new method of dealing with the open_existing functions is necessary.
| |
− | *20 June:
| |
− | **Continued studying how to integrate the open_existing function.
| |
− | *21 June:
| |
− | **Break day.
| |
− | *22 June:
| |
− | **Worked at the open_existing function.
| |
− |
| |
− | ==Week 6==
| |
− | *Weekly milestone:
| |
− | **Finish the open_existing function
| |
− | *23 June:
| |
− | **Worked on raytracing from the display manager.
| |
− | *24 June:
| |
− | **Break day.
| |
− | *25 June:
| |
− | **Created the midterm report that can be found [http://brlcad.org/wiki/User:Vladbogolin/GSoC2014/Midterm here]
| |
− | *26 June:
| |
− | **Processed events so that the output is displayed line by line
| |
− | **Fixed the upside down drawing problem:

| |
− | *27 June:
| |
− | **Break day.
| |
− | *28 June:
| |
− | **Started modifying the fbio interface in order to add a generic open_existing entry.
| |
− | *29 June:
| |
− | **Mostly a break day.
| |
− |
| |
− | ==Week 7==
| |
− | *Time spent preparing my final project
| |
− |
| |
− | ==Week 8==
| |
− | *Weekly milestone:
| |
− | **Finish modifying the interface in order to use the open_existing function
| |
− | *7-8 July:
| |
− | **Had my final paper presentation. Now I can focus only on GSoC for the rest of the summer.
| |
− | *9 July:
| |
− | **Added a new entry in struct dm so that the framebuffer can be opened from libdm. This is necessary in order to avoid using qt code in mged/dm-qt and also can be used for refactoring dm related code from mged folder.
| |
− | **Added the _qt_open_existing function in fb.h. This is a temporary solution until a final form of the function is implemented. In the end a new entry will be added in the fbio interface.
| |
− | **Opened the framebuffer from the display manager, but at the moment there are two different windows.
| |
− | *10 July:
| |
− | **Continued working at the open_existing function. Hopefully it will be done by the end of the week.
| |
− | *11 July:
| |
− | **Struggled more with the embedding of a framebuffer window.
| |
− | *12 July:
| |
− | **More struggle regarding the display of raytraced objects from the display manager.
| |
− | *13 July:
| |
− | **Mostly a break day.
| |
− |
| |
− | ==Week 9==
| |
− | *Weekly milestone:
| |
− | **Finish the embedding of a framebuffer window
| |
− | *14 July:
| |
− | **Worked at the actual embedding of a framebuffer window - still couldn't find a working solution
| |
− | *15 July:
| |
− | **Did a deeper research on how the existing implementation is done. Still couldn't find a way do display content in the embedded window.
| |
− | *16 July:
| |
− | **Break day
| |
− | *17 July:
| |
− | **After a lot of struggle, I have finally found a solution that seems to solve all the problems. Hopefully tomorrow there would be content displayed in the embedded framebuffer window.
| |
− | *18 July:
| |
− | **After using a QPainter to draw the raytraced content in the existing window, content can be displayed so I am on the right track with the embedding. There still are some fixes that need to be done: when the raytracing is done the drawn content disappears and also a few fixes regarding the position of the drawn image are necessary.
| |
− | *19 July:
| |
− | **Tried to solve the problems regarding the embedding so I did a little more research on why the content disappears but with no luck yet.
| |
− | *20 July:
| |
− | **Tried to solve the problem regarding the position of the drawn image.
| |
− |
| |
− | ==Week 10==
| |
− | *Weekly milestone:
| |
− | **Have a working framebuffer.
| |
− | *21 July:
| |
− | **Implemented the configureWindow function.
| |
− | **Continued trying to solve the problem regarding the position of the drawn image - still no luck.
| |
− | **Redesigned the write function in order to solve the display problem - there still are some fixes that need to be made.
| |
− | *22 July:
| |
− | **Continued working at the new write function.
| |
− | *23 July:
| |
− | **Solved the display problem - now correct drawings can be made in the embedded framebuffer window:

− | [[File:Mged_fb.png|500px]]
| |
− | [[File:Mged_fb2.png|500px]]
| |
− | *24 July:
| |
− | **Tried to find out why the image disappears after is drawn in the embedded framebuffer window - more research needs to be done since I haven't found the problem.
| |
− | *25 July:
| |
− | **Break day
| |
− | *26 July:
| |
− | **Break day
| |
− | *27 July:
| |
− | **More research regarding the disappearing of the drawings - found the problem (after the raytracing the dm redraws the entire window and the raytraced content erases in this way) and tried to come up with a solution.
| |
− |
| |
− | ==Week 11==
| |
− | *28 July:
| |
− | **Continued trying to solve the disappearing problem.
| |
− | *29 July:
