void Viewport::draw (  DrawAction *  action  )  [virtual, inherited]
 

Draw the viewport. Restrict the OpenGL rendering to the given part of the window, clear it, draw it using the given DrawAction and add the Foregrounds.

The _sfCamera, _sfBackground and _sfRoot Fields need to be valid, otherwise drawing will fail.

Dev:

Activates scissoring only if the viewport doesn't fill the wholw window, as it significantly slows down some OpenGL implementations.
