Sightline Analysis

Challenge:
Proof of concept for creating a sightline analysis. Which is a way of showing the field of view for a pedestrian in a simulation

Solution:

The algoritme creates a number of marks (Shaperectangles) in the place of Walls and ShapLines. These are used to graphically display how "visible" that area is.
every few seconds the pedestrian will calculate which marks are visible based on the which marks are within the view (the three arcs) and not shadowed by another object.

Results:

The result is used to help improve wayfinding by showing where pedestrian are most likely looking.

Still need some tweaking regarding how different marks are prioritised. eg. walls parallel to the walking direction should be priotrized less than it currently is.
