                             FilledCircle

    A circular stimulus, typically used as a fixation point.

    (Note, this implementation almost certainly could be made faster
    using display lists.)

    Parameters
    ==========
    anchor        -- how position parameter is used (String)
                     Default: center
    anti_aliasing -- (Boolean)
                     Default: True
    color         -- color (AnyOf(Sequence3 of Real or Sequence4 of Real))
                     Default: (1.0, 1.0, 1.0)
    num_triangles -- number of triangles used to draw circle (Integer)
                     Default: 51
    on            -- draw? (Boolean)
                     Default: True
    position      -- position in eye coordinates (AnyOf(Sequence2 of Real or Sequence3 of Real or Sequence4 of Real))
                     Default: (320.0, 240.0)
    radius        -- radius in eye coordinates (Real)
                     Default: 2.0

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)
