Constructor Detail

Ilv3DExtrudedPolygon

public Ilv3DExtrudedPolygon(double[] lonCoords,
                            double[] latCoords,
                            double baseElevation,
                            double topElevation)

Constructs an Ilv3DExtrudedPolygon from the specified parameters.

Parameters:

lonCoords - An array of longitude coordinates in radians.

latCoords - An array of latitude coordinates in radians.

baseElevation - The elevation of the base of this Ilv3DExtrudedPolygon, in meters.

topElevation - The elevation of the top of this Ilv3DExtrudedPolygon, in meters.

Method Detail

pathUpdated

public void pathUpdated()

A method that recomputes internal variables when the path of the corridor changes. It must be called whenever the arrays passed to the constructor change to avoid drawing garbage.

getCenterLongitude

public double getCenterLongitude()

Returns the longitude of the center of this component.

Specified by:

getCenterLongitude in interface Ilv3DComponent

Returns:

The longitude of the center in radians.

getCenterLatitude

public double getCenterLatitude()

Returns the latitude of the center of this component.

Specified by:

getCenterLatitude in interface Ilv3DComponent

Returns:

The latitude of the center in radians.

getCenterElevation

public double getCenterElevation()

Returns the elevation of the center of this component.

Specified by:

getCenterElevation in interface Ilv3DComponent

Returns:

The elevation Of the center in meters.

display

public void display(GL2 gl,
                    Ilv3DCoordinateConverter converter)

Draws this component inside the specified OpenGL GL context object. The context is centered on the center of this component. Any drawing must be done in 3D space coordinates, which are computed through the use of the Ilv3DCoordinateConverter provided.

Specified by:

display in interface Ilv3DComponent

Parameters:

gl - The OpenGL context.

converter - The Ilv3DCoordinateConverter that converts from geographic coordinates to 3D coordinates.

Returns:

The java.awt.Color of this component.

setColor

public void setColor(Color color)

Sets the color of this component.

Parameters:

color - The java.awt.Color to set.
