The demo is using libQGLviewer.

See setBackgroundColor()

Hello, I am new to CGAL, and want to develop project using it.

I am using Alpha_shapes_3 demo as my base project and modifying upon it.

I wonder how I can change the background color of the OpenGL viewer?
Currently, it is gray, but I want it to be white. I did not find a place to
change it. I have not learned OpenGL shaders yet, but have knowledge of
OpenGL fixed function pipeline.

Thank you very much.
