Interface DynamicSpatialObject

All Superinterfaces:
SpatialObject
All Known Implementing Classes:
Gtu
public interface DynamicSpatialObject extends SpatialObject
DynamicSpatialObject has two shapes: the shape that is registered in the Map is the shape that indicates where the object can be present for the time frame for which intersections can be calculated. This is, for instance, a contour that indicates the Minkowski sum of the locations of a GTU for the next time step. This contour IS registered in the spatial tree. The getShape(time), however, provides the exact shape of the GTU at a fixed time instant. This contour is NOT registered in the spatial tree.

  • Method Details

    • getShape

      OtsShape getShape(Time time)
      Return the shape of a dynamic object at time 'time'. Note that the getShape() method without a time returns the Minkowski sum of all shapes of the spatial object for a validity time window, e.g., a contour that describes all locations of a GTU for the next time step, i.e., the contour of the GTU belonging to the next operational plan.
      Parameters:
      time - Time; the time for which we want the shape
      Returns:
      OtsShape; the shape of the object at time 'time'

    • transformShape

      default OtsShape transformShape(OtsShape shape, DirectedPoint p) throws OtsGeometryException
      Return the contour of the dynamic object at the right position and in the right direction.
      Parameters:
      shape - OtsShape; the shape to translate and rotate for point p
      p - DirectedPoint; the location and direction of the reference point of the object
      Returns:
      Polygon2d; the contour of the dynamic object at the right position and in the right direction
      Throws:
      OtsGeometryException - on invalid geometry after transformation
