How to check all spectators' view in the Hakataza theater by using PC

I confirmed whether all spectators saw the actors on the stage and the elevated passageway leading to the stage of the Hakataza theater while using PC. (cf. photograph) Photographs were taken in 1996. PC was NEC98. OS was MS-DOS. Modeling software was ARM. I was checking it by models of spectator such as ritual images of warriors and horses. (The date of the photograph is wrong.)
