//in most rendering packages has been presented. If single panoramic pairs can be created
//then stereoscopic panoramic movies are equally possible giving rise to the prospect of
//movies where the viewer can interact with, at least with regard to what they choose to look
//at.These images can be projected so as to engage the two features of the human visual
//system that assist is giving us a sense of immersion, the feeling of “being there”. That is,
//imagery that contains parallax information as captured from two horizontally separated eye
//positions (stereopsis)and imagery that fills our peripheral vision.The details that define
//how the two panoramic images should be created in rendering packages are provided, in
//particular, how to precisely configure the virtual cameras and control the distance to zero
