There is a Qt Display Manager which will be used in BRL-CAD. But qt framebuffer is currently not embedded inside the window. This is because the window is created using Tk. So the task would be to create a Qt window and then embed the qt framebuffer inside it.
I compiled BRL-CAD’s qtged branch against qt for checking this out instead of the trunk source.
The first step is to get myself familiar with MGED(Multi-Device Geometry Editor) in BRL-CAD.
I am learning to create models inside MGED using commands as well as GUI.
