QGLViewer allows people programming in OpenGL to play around with three dimensional scenes or to write software that uses OpenGL. It provides a set of classes for camera control, as well as comfortable user interface that allows you to control your viewing parameters via mouse and buttons.

QGLViewer is object oriented and programmed in C++ such that the programmer simply instantiates a viewer and connects it to their own render routines.
