Method Details

__init__(self, left=0.0, right=640.0, bottom=0.0, top=480.0)
(Constructor) 

Create an orthographic projection without Z clipping.

Defaults to map x eye coordinates in the range [0,640] and y
eye coordinates [0,480] -> [0,1].  Therefore, if the viewport
is 640 x 480, eye coordinates correspond 1:1 with window
(pixel) coordinates.
Overrides:
VisionEgg.Core.Projection.__init__
