    • goToObject

      Warning: This method is not deterministic. It is implemented as a loop that sends 'camera forward' events to the main thread, running in a separate thread. If you need total synchronization and reproducibility, look into the parkRunnable(String, Runnable) family of calls.

      Parameters:

If waitTimeSeconds is positive, it indicates the number of seconds to wait (block the function) for the camera to face the focus before starting the forward movement. This very much depends on the turn velocity of the camera. See setTurningCameraSpeed(float).

      Warning: This method is not deterministic. It is implemented as a loop that sends 'camera forward' events to the main thread, running in a separate thread. If you need total synchronization and reproducibility, look into the parkRunnable(String, Runnable) family of calls.

      provider - The coordinate provider instance.
    • removeObjectCoordinatesProvider

      void removeObjectCoordinatesProvider(String name)

    • addTrajectoryLine

      void addTrajectoryLine(String name, double[] points, double[] color)

This is a very similar call to addPolyline(String, double[], double[]), but in this case the line can be rendered with higher quality polyline quadstrips.
      Parameters:
      name - The name to identify the trajectory, to possibly remove it later.
      points - The points of the trajectory. It is an array containing all the points as in [x0, y0, z0, x1, y1, z1, ..., xn, yn, zn] in the internal reference system.
      color - The color of the trajectory as an array of RGBA (red, green, blue, alpha) values in [0,1].
    • addTrajectoryLine

      void addTrajectoryLine(String name, double[] points, double[] color, double trailMap)
      Adds a new trajectory object with the given name, points and color. The trajectory is rendered using the 'line renderer' setting in the preferences dialog. This is a very similar call to addPolyline(String, double[], double[]), but in this case the line can be rendered with higher quality polyline quadstrips.
      Parameters:
      name - The name to identify the trajectory, to possibly remove it later.
      points - The points of the trajectory. It is an array containing all the points as in [x0, y0, z0, x1, y1, z1, ..., xn, yn, zn] in the internal reference system.
      color - The color of the trajectory as an array of RGBA (red, green, blue, alpha) values in [0,1].
      trailMap - The bottom mapping position for the trail. The orbit trail assigns an opacity value to each point of the orbit, where 1 is the location of the last point in the points list, and 0 is the first one. This mapping parameter defines the location in the orbit (in [0,1]) where we map the opacity value of 0. Set to 0 to have a full trail. Set to 0.5 to have a trail that spans half the orbit. Set to 1 to have no orbit at all. Set to negative to disable the trail.

    • cameraOrientationTransition

      void cameraOrientationTransition(double[] camDir, double[] camUp, double durationSeconds, String smoothType, double smoothFactor, boolean sync)

      Creates a smooth transition from the current camera orientation to the given camera orientation {camDir, camUp} in the given number of seconds.

      This function accepts smoothing type and factor.

      Optionally, this call may return immediately (async) or it may wait for the transition to finish (sync).

      This function puts the camera in free mode, so make sure to change it afterward if you need to. Also, this only works with the natural camera.

      Parameters:
      camDir - The target camera direction in the internal reference system.
      camUp - The target camera up in the internal reference system.
      durationSeconds - The duration of the transition in orientation, in seconds.
      smoothType - The function type to use for the smoothing of orientations. Either "logit", "logisticsigmoid" or "none".
      • "logisticsigmoid": starts slow and ends slow. The smooth factor must be over 12 to produce an effect, otherwise, linear interpolation is used.
      • "logit": starts fast and ends fast. The smooth factor must be between 0.09 and 0.01.
      • "none": no smoothing is applied.
      smoothFactor - Smooth factor for the orientations (depends on type).
      sync - If true, the call waits for the transition to finish before returning, otherwise it returns immediately.

      durationSeconds - The duration of the transition, in seconds.
      smoothType - The function type to use for smoothing. Either "logit", "logisticsigmoid" or "none".
      • "logisticsigmoid": starts slow and ends slow. The smooth factor must be over 12 to produce an effect, otherwise, linear interpolation is used.
      • "logit": starts fast and ends fast. The smooth factor must be between 0.09 and 0.01.

      Be careful with this function, as it probably needs a cleanup before the script is finished. Otherwise, all parked runnables will keep running until Gaia Sky is restarted, so make sure to remove them with unparkRunnable(String) if needed.

      void backupSettings()

      Creates a backup of the current settings state that can be restored later on. The settings are backed up in a stack, so multiple calls to this method put different copies of the settings on the stack in a LIFO fashion.

      This method, together with restoreSettings(), are useful to back up and restore the settings at the beginning and end of your scripts, respectively, and ensure that the user settings are left unmodified after your script ends.

    • restoreSettings

      boolean restoreSettings()

      Takes the settings object at the top of the settings stack and makes it effective.

      This method, together with backupSettings(), are useful to back up and restore the settings at the beginning and end of your scripts, respectively, and ensure that the user settings are left unmodified after your script ends.

      WARN: This function applies all settings immediately, and the user interface may be re-initialized. Be aware that the UI may be set to its default state after this call.

      Returns:
      True if the stack was not empty and the settings were restored successfully. False otherwise.
    • clearSettingsStack

      void clearSettingsStack()
      Clears the stack of settings objects. This will invalidate all previous calls to backupSettings(), effectively making the settings stack empty. Calling restoreSettings() after this method will return false.
    • resetUserInterface

      void resetUserInterface()
      Forces a re-initialization of the entire user interface of Gaia Sky on the fly.
    • setMaximumSimulationTime

      void setMaximumSimulationTime(long years)

      Parameters:
      years - The maximum year number to allow.
