3-D cockpit simulator displays-achieving precise depth placement of objects in graphic images

The authors have developed software routines to produce 3-D images that can be used with any application. Each graphics application tends to have unique features such as the size of objects being drawn or the coordinate system in which these objects are displayed. For example, one application may display objects such as aircraft in a situational display while another displays aircraft system status information. Clearly, coordinate systems and object sizes will differ between these two applications. The stereographic software techniques described are compatible with any coordinate system or size of object and are also compatible with other graphic transformations such as rotation and translation. Stereographic theory is explained in the context of these software procedures as applied in a study of a 3-D situational display. Ultimately, the combination of this software and respective explanation will enable any user to develop and display 3-D images, reliably placing graphic objects in space
