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).
