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)
