Fig. 1. (A) Illustration of the space around a signalling lizard, divided into
45° sectors and three concentric circles at distances of 1, 3 and 6 m. We
created stimulus sequences of each motor pattern by recording at points given
by the intersection of the concentric circles and at angles of 0, 45 and
90° (filled circles). The empty circles represent views that were not
sampled but which are not likely to be different to the positions chosen. The
space behind the lizard was not included, as lizards do not typically display
when oriented in a direction away from an intended receiver. (B) A schematic
illustration of how the different viewing angles were generated by shifting
the location of the camera object in the animation software. The drawings show
how changing the location of the camera influenced the view of the tail-flick
(top panel), foreleg wave (middle panel) and push-up (bottom panel) for the
three camera locations shown in (A).
