A computational model of stereoscopic prey capture in praying mantises
Fig 8
Top-down view (not to scale) of a mantis viewing a computer screen at a distance S.
To simulate an object at distance D from the mantis, the left and right eye’s images (labelled L, R) need to be separated by a distance P on the screen. The angle subtended by the distance P at the mantis is the screen disparity α; the retinal disparity Δ of the virtual object is the angle subtended by the interocular distance I at the virtual object.
