addPoints

public void addPoints(double[] points)

Adds the given vector to the current points. The vector is of the form [x0, y0, z0, x1, y1, z1, ..., xn, yn, zn]. If the size of the vector is not a multiple of 3, no points are added

Parameters:

points - The points to add to this point cloud

addPoints

public void addPoints(java.util.ArrayList points)

Same as addPoints(double[]) but with an array list

Parameters:

points - The points to add to this point cloud

addPoint

public void addPoint(Vector3d point)

Adds a single point o this point cloud

Parameters:

point - The point

addPoint

public void addPoint(double x,
                     double y,
                     double z)

Adds a single point to the cloud

Parameters:

x - The x component

y - The y component

z - The z component

loadPoint

public void loadPoint(Vector3d v,
                      int index)

Loads the data point at the index in the vector in the Orbit reference system

Parameters:

v -

index -

Loads the data point at the index in the vector in the world reference system

Parameters:

v -

index -

loadPoint

public boolean loadPoint(Vector3d v,
                         java.time.Instant instant)

Returns a vector with the data point at the given time. It uses linear interpolation. The time instant must be within the bounds of this point cloud's times

Parameters:

v - The vector

instant - The time as an instant

Returns:

Whether the operation completes successfully

loadPoint

public boolean loadPoint(Vector3d v,
                         long timeMs)

Returns a vector with the data point at the given time. It uses linear interpolation. The time instant must be within the bounds of this point cloud's times

Parameters:

v - The vector

timeMs - The time in milliseconds

Returns:

Whether the operation completes successfully

getWrapTimeMs

public long getWrapTimeMs(java.time.Instant instant)

getIndex

public int getIndex(java.time.Instant instant)

Gets the bounding indices for the given date. If the date is out of range, it wraps.

Parameters:

instant - The date

Returns:

The two indices

getIndex

public int getIndex(long wrappedTimeMs)
