# Module Core

source code

    Core Vision Egg functionality.

    This module contains the architectural foundations of the Vision Egg.

Classes

| ProjectionBaseClass Converts stimulus coordinates to viewport coordinates.
| Projection for use of OpenGL PROJECTION_MATRIX...
| ModelView for use of OpenGL MODELVIEW_MATRIX...
| OrthographicProjection An orthographic projection.
| OrthographicProjectionNoZClip An orthographic projection without Z clipping.
| SimplePerspectiveProjection A simplified perspective projection.
| PerspectiveProjection A perspective projection.
| Stimulus Base class for a stimulus.
| Viewport Connects stimuli to a screen.
| FixationSpot A rectangle stimulus, typically used as a fixation spot.
| FrameTimer Time inter frame intervals and compute frames per second.
| Message DEPRECATED Handles message/warning/error printing, exception raising.
