Hello John,
For typical high ceiling room 9 feet and AoV 360 with most comment camera resolution 1080 the width of scene = 6.28 x 9 = 56.5 and PPF =34. Also same result of Aov 180 when we increase the resolution and same data input just the PPF will increase
The question what is the dimension of each wall in the room (square, rectangular). For example, we have room with dimension of 12L x 12W x 9H it is covered.
