Specifies a parallel camera for rendering a scene without perspective correction.
If a scene contains only 2D transforms, then the following details are not relevant. This camera defines a viewing volume for a parallel (orthographic) projection; a rectangular box. This camera is always located at center of the window and looks along the positive z-axis. The coordinate system defined by this camera has its origin in the upper left corner of the panel with the Y-axis pointing down and the Z axis pointing away from the viewer (into the screen). The units are in pixel coordinates.
