Method Details

### __init__(self, **kw) (Constructor) | source code
    Instantiate and get ready to draw.

    Set parameter values and create anything needed to draw the
    stimulus including OpenGL state variables such display lists
    and texture objects.
Overrides: Core.Stimulus.__init__ (inherited documentation)

### draw(self) | source code
    Draw the stimulus. (Called by Viewport instance.)

    This method is called every frame.  This method actually
    performs the OpenGL calls to draw the stimulus.
Overrides: Core.Stimulus.draw (inherited documentation)
