Embedding a framebuffer window[edit]
The project can be split into two main parts:
- Creating a new Qt framebuffer
- Embedding a framebuffer window
I started by creating a new cross-platform Qt framebuffer which was implemented almost completely until midterm evaluation. More information about my work in that period can be found here.
In the second part I worked at embedding a framebuffer window in the existing Qt display manager. Even though I encountered quite a lot of unexpected problems (bad drawings, drawings that disappeared) in the end I managed to successfully embed a framebuffer window. I can say that when I saw correct and permanent drawings made in mged I was really relieved and also really excited.
Apart from embedding a framebuffer window, I also added support for keyboard and mouse events and for using, reading and writing a colormap to the framebuffer.
When it comes to the actual code, it can almost all be found in libfb/if_qt.cpp and libdm/dm-qt.cpp. As I predicted in the first part, in order to embed a frambuffer window another 800 lines of code were necessary.
Results[edit]
As you can see from the below pictures the framebuffer is integrated with the raytracer and it can successfully display raytraced models.
When it comes to embedding a frambuffer window, I tested the behavior in both mged
and archer
More infos about the development process can be found on the log page
