Constructor Details

AbstractFieldOfView

protected AbstractFieldOfView(double margin)

Build a new instance.

Parameters:

margin - angular margin to apply to the zone (if positive, points outside of the raw FoV but close enough to the boundary are considered visible; if negative, points inside of the raw FoV but close enough to the boundary are considered not visible)

Method Details

getMargin

public double getMargin()

Get the angular margin to apply (radians). If angular margin is positive, points outside of the raw FoV but close enough to the boundary are considered visible. If angular margin is negative, points inside of the raw FoV but close enough to the boundary are considered not visible

Specified by:

getMargin in interface FieldOfView

Returns:

angular margin
