Constructor Detail

Ilv3DSphere

public Ilv3DSphere(double centerLongitude,
                   double centerLatitude,
                   double elevation,
                   double radiusInMeters)

Constructs an Ilv3DSphere from the specified parameters.

Parameters:

centerLongitude - The longitude of the center of this component in radians.

centerLatitude - The latitude of the center of this component in radians.

elevation - The elevation of the center of this component in meters.

radiusInMeters - The radius of this Ilv3DSphere in meters.

Method Detail

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.

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.

Ilv3DCoordinateConverter

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.

getColor

public Color getColor()

Returns the color of this component.

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.

getElevationSteps

public int getElevationSteps()

Returns the number of steps along the elevation axis used to draw the sphere (that is, stacks). The higher this number, the smoother the aspect of the sphere, but the longer it takes to draw.

Returns:

The number of steps along the elevation axis.

setElevationSteps

public void setElevationSteps(int elevationSteps)

Sets the number of steps along the elevation axis used to draw the sphere (that is, stacks). The higher this number, the smoother the aspect of the sphere, but the longer it takes to draw. Default value is 20.

Parameters:

elevationSteps - The number of steps along the elevation axis to be set.

getLonLatSteps

public int getLonLatSteps()

Returns the number of steps about the elevation axis used to draw the sphere (that is, slices). The higher this number, the smoother the aspect of the sphere, but the longer it takes to draw.

Returns:

The number of steps along the elevation axis.

setLonLatSteps

public void setLonLatSteps(int lonLatSteps)

Sets the number of steps about the elevation axis used to draw the sphere (that is, slices). The higher this number, the smoother the aspect of the sphere, but the longer it takes to draw.

Parameters:

lonLatSteps - The number of steps about the elevation axis.

getRadius

public double getRadius()

Returns the radius of this Ilv3DSphere.

Returns:

The radius in meters.

setRadius

public void setRadius(double radiusInMeters)

Sets the radius of this Ilv3DSphere.

Parameters:

radiusInMeters - The radius in meters.
