The eqHello example is a minimal application to illustrate the basic principle
of an Equalizer application: The application developer has to implement the
rendering method Channel::frameDraw, similar to
the glutDisplayFunc in GLUT applications. It can be run as a
stand-alone application from the command line.
The eqHello redraw function renders six rotating, colored quads around the
origin. The frameDraw method provided by
the eq::Channel can be used as a convience function to setup the
frustum and other OpenGL state. After setting up some additional lighting
parameter, eqHello rotates the scene and render the quads using immediate mode
rendering.
