Method Details

__init__(self, **kw)
(Constructor) 

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:
VisionEgg.Core.Stimulus.__init__ (inherited documentation)

draw(self) 

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:
VisionEgg.Core.Stimulus.draw (inherited documentation)

Class Variable Details

constant_parameters_and_defaults

Type:
dict
Value:
{'texture_size': ((64, 64),
                  <VisionEgg.ParameterTypes.Sequence2 object at 0x40f2\
10ac>)}

parameters_and_defaults

Type:
dict
Value:
{'on': (True, <class 'VisionEgg.ParameterTypes.Boolean'>),
 'position': ((320, 240),
              <VisionEgg.ParameterTypes.Sequence2 object at 0x40f1ffac\
>),
 'size': ((64, 64), <VisionEgg.ParameterTypes.Sequence2 object at 0x40\
