public class CustomOrbitView
extends gov.nasa.worldwind.view.orbit.BasicOrbitView

This custom class allows the user to specify the near and far clip distances to allow the viewing of objects beyond the Earth's horizon (such as trajectories). The class hierarchy is as follows: BasicView -BasicOrbitView -CustomerOrbitView BasicOrbitView is derived from BasicView which models the view in terms of a geographic position, and a pitch, heading, and roll. It provides a mapping from the geocentric view model to a 3D graphics modelview matrix. BasicView also manages the projection matrix via a Frustum.

Method Detail

setClipDistValues

public void setClipDistValues(double nCD,
                              double fCD)

The purpose is for the user to set the near and far clip distances to be stored in this class.

Parameters:

nCD - The "near" clip distance.

fCD - The "far" clip distance.

computeNearClipDistance

protected double computeNearClipDistance()

The purpose is to set a custom near clip distance so that trajectories don't get "cut off" on the other side of the Earth. This method is inherited from base class BasicView and modified (Overridden).

Overrides:

computeNearClipDistance in class gov.nasa.worldwind.view.BasicView

Returns:

The near clip distance value.

computeFarClipDistance

protected double computeFarClipDistance()

The purpose is to set custom far clip distance so that trajectories don't get "cut off" on the other side of the Earth. This method is inherited from base class BasicView and modified (Overridden).

Overrides:

computeFarClipDistance in class gov.nasa.worldwind.view.BasicView

Returns:

The far clip distance value.
