ISOPTIC relative to the isoptic, condition of equal visibility for the whole audience to an event, which allows viewers to fully visualize a specific area, usually the center of the stage In the case of vertical isoptic we must overcome the difficulty of allowing a correct visibility in contiguous rows of spectators, which is usually achieved by staggering their seats. In the case of the horizontal isoptic, we must worry about the restriction of the viewing angles and potential obstructions that the spectators will have towards the sports space where the show takes place.
