As result of previous BRL-CAD Alternative GUI tasks a reference version of an alternative BRL-CAD GUI was created and submitted to the rt^3 branch of the BRL-CAD subversion repository. This task is about improving QtGUI.

As a prerequisite for this task you should have fulfilled the following steps:

• Compile and install BRL-CAD
• Download the rt^3 source tree (see https://brlcad.org/wiki/SVN)
• Set up the build environment by using the top level CMakeLists.txt file
• Build the QtGUI target
• Run the QtGUI program and test it

To perform this task, improve the input of rotation angles. Currently, these angles can be given by turning dials. But, this could be too imprecise. Accompany these dials with controls where the user may put in the exact numbers.

When you are done, please submit

• A patch file with your changes to the source code and
• A screen shot of the QtGUI program window
