Thank you for the explanation.

djordje,

Yes, you have understood correctly.

So in first and third example: the criteria was to identify a point on the path with the maximal 2d visibility angle? Those being 28 and 120 degrees measured in horizontal plane?
In second example the criteria was to find the maximal 2d visibility area (123.29...) for the defined visibility distance?
Did I understand that correctly or not?

Thanks djordje,

In the first example ('outdoor') the graph represents the total angle of visibility from the viewpoint in real time. 28 is the maximum value of the path.
In the second example('indoor') 2d visibility areas in square meters from the viewpoint. 123.29.. is the maximum value of the path.
Finally in the third example ('indoor/outdoor') the total angle of visibility from the viewpoint with a distance limits of 20 meters.

Quite interesting project!!
What do the values in the Quick graph represent? The 2d area visible from particular point along the path?
What do "28" in first example and "120" in the second represent? 2d visibility areas in square meters?
