# User Interface files ...
#
# Despite their ".cel" file extension, these are not CEL scripts, but
# rather data files that populate controls such as menus and dialog
# boxes.
#
# FavoritesFile
# -------------
# This is where Bookmarks data are stored. The file does not exist until
# you save a Bookmark from within Celestia. You can view this file with
# a plain text editor and if you write CEL scripts, it contains some
# useful information.
#
# DestinationFile
# ---------------
# This is the list of Destinations used in the Tour Guide dialog box,
# accessed via the Navigation Menu. You can edit this file with a plain
# text editor to add your own destinations to the dialog box. The order
# in which the items are listed in the file is the order in which they
# will be listed in the Tour Guide dialog.
#
# Cursor
# ------
# This parameter allows you to select from three cursors, but currently
# only in the Windows version of Celestia ...
#  * White crosshair ("crosshair") --> default cursor
#  * Inverting crosshair ("inverting crosshair")
#  * Standard Windows arrow ("arrow")
#
# The inverting crosshair can be a better choice because it's more
# visible on bright backgrounds. However, should you decide to try this
# cursor, TEST IT CLOSELY. Not all graphics chipsets support an inverting
# cursor, which will cause Windows to fall back to software emulation.
# The emulated cursor interacts with OpenGL applications in unfortunate
# ways, forcing a lot of extra redrawing and cutting by half the frame
# rate on a GeForce2-equipped laptop. So, if you change this, check your
# FPS rates to make sure you haven't kicked Windows into software
# emulation mode.
#------------------------------------------------------------------------
  FavoritesFile    "favorites.cel"
  DestinationFile  "guide.cel"
  Cursor           "crosshair"


#------------------------------------------------------------------------
# Included CEL script files.
#
# The following CEL script files are included in the basic Celestia
# distribution. These script files may be viewed and edited with a
# plain text editor. They may both be modified or replaced to suit your
# specific needs.
#
# InitScript is the CEL script that is automatically run each time
# Celestia is started. The default script (start.cel) travels to Io, one
# of Jupiter's moons.
#
# DemoScript is the CEL script that is run when you select the "Run Demo"
# option in the File menu in Celestia. The default script (demo.cel)
# takes you on a short tour of some interesting places in our solar
# system.
#
# To learn more about how to use and write CEL scripts and Lua scripts
# in Celestia, please visit the Celestia Scripting forum at:
#   https://celestiaproject.space/forum/viewforum.php?f=9
#------------------------------------------------------------------------
  InitScript  "start.cel"
  DemoScript  "demo.cel"


#------------------------------------------------------------------------
# The 'extras' directory is located under the celestia root directory
# and is used for storing third-party add-ons to Celestia. To learn
# more about Add-Ons for Celestia, visit the Celestia Add-Ons forum at:
#   https://celestiaproject.space/forum/viewforum.php?f=6
#
# You may specify additional add-on directories by adding additional
# entries, such as the following example shows:
# ExtrasDirectories  [ "extras" "myextras1" "myextras2" ]
#
# To specify absolute paths on windows, you either have to use "/" or
# double backslashes to seperate path components. Example:
#   ExtrasDirectories  [ "D:/celestia-extras" ]
# or
#   ExtrasDirectories  [ "D:\\celestia-extras" ]
#------------------------------------------------------------------------
  ExtrasDirectories  [ "extras-standard" "extras" @CELCFG_EXTRAS_DIRS@]


#------------------------------------------------------------------------
# Addons in 'extras' directories can be skipped. For example, if you have
# an addon which provides a better version of ISS spacecraft you might
# want to use it instead of the default one shipped with Celestia. But if
# you load it you will have two spacecraft rendered in the same place. So
# you can either remove the default one but it will be reinstalled on
# Celestia upgrade or you can it to the skip list. Example:
#   SkipExtras "extras-standard/iss/iss.ssc"
# or
#   SkipExtras ["extras/wostars.stc" "extras-standard/iss/iss.ssc"]
#
# Please note that 1) only relative paths work, 2) directories are not
# accepted in the list only catalog file names.
#------------------------------------------------------------------------
#  SkipExtras [ ]

#------------------------------------------------------------------------
# Font definitions.
#
# The following entries define the fonts Celestia will use to display
# text on the display screen. To view the list of fonts available with
# your distribution of Celestia, look in the fonts directory located
# under the Celestia root directory. The default fonts are UTF-8
# compatible in order to display non-English characters. Font size is
# measured in points to ensure the same sizes on all DPI configurations.
#
# Font:      Used to display all informational text.
#            Default: "DejaVuSans.ttf,9"
#
# LabelFont: Used to display all label text (objects, locations, etc.).
#            Default "DejaVuSans.ttf,9"
#
# TitleFont: Used to display object names, messages, and script text.
#            Default "DejaVuSans-Bold.ttf,15"
#------------------------------------------------------------------------
  Font       "DejaVuSans.ttf,9"
  LabelFont  "DejaVuSans.ttf,9"
  TitleFont  "DejaVuSans-Bold.ttf,15"


#------------------------------------------------------------------------
# LogoTexture defines the graphic file to be displayed when Celestia is
# started. The default filename is "logo.png"
#------------------------------------------------------------------------
  LogoTexture  "logo.png"


#------------------------------------------------------------------------
# FaintestVisibleMagnitude defines the lowest magnitude at which a star
# will be displayed in Celestia. This setting may be adjusted real-time
# via the '[' and ']' keys in Celestia. The default value is 6.0.
#------------------------------------------------------------------------
  FaintestVisibleMagnitude 6.0


#------------------------------------------------------------------------
# RotateAcceleration defines the speed at which an object will be
# rotated in Celestia, when using a keypress, such as the left and right
# arrow keys. A higher value will rotate the object quicker, while a
# lower value will cause a slower rotation. The default value is 120.0.
#------------------------------------------------------------------------
  RotateAcceleration 120.0


#------------------------------------------------------------------------
# MouseRotationSensitivity defines the speed at which an object will be
# rotated in Celestia, when using the mouse -- press both mouse-buttons
# or Ctrl+LeftMouseButton, and move the mouse left or right. A higher
# value will rotate the object quicker, while a lower value will cause
# a slower rotation. A value of 0.0 (zero) will disable this particluar
# feature. The default value is 1.0.
#------------------------------------------------------------------------
  MouseRotationSensitivity 1.0


#------------------------------------------------------------------------
# ReverseMouseWheel performs a change of command rotates
# the mouse wheel on the opposite. The default value is false.
# RayBasedDragging enables dragging behavior that based on change of
# pick rays instead of screen coordinates. The default value is false.
# FocusZooming enables the zooming behavior where the focus location on
# screen is kept. The default value is false.
#------------------------------------------------------------------------
#  ReverseMouseWheel true
#  RayBasedDragging  true
#  FocusZooming      true


#------------------------------------------------------------------------
# The following parameter is used in Lua (.celx) scripting.
#
#   ScriptScreenshotDirectory defines the directory where screenshots
#   are to be stored. The default value is "", i.e. Celestia's
#   installation directory.
#------------------------------------------------------------------------
  ScriptScreenshotDirectory ""


#------------------------------------------------------------------------
# CELX-scripts can request permission to perform dangerous operations,
# such as reading, writing and deleting files or executing external
# programs. If granted, a malicious script could use this to destroy
# data or compromise system security.
# The following parameter determines what Celestia does upon such
# requests:
#  "ask": ask the user if he want's to allow access (default)
#  "allow": always allow such requests
#  "deny": always deny such requests
#------------------------------------------------------------------------
  ScriptSystemAccessPolicy "ask"


#------------------------------------------------------------------------
# The following lines are render detail settings.  Assigning higher
# values will produce better quality images, but may cause some older
# systems to run slower.
#
#   OrbitPathSamplePoints defines how many sample points to use when
#   rendering orbit paths. The default value is 100.
#
#   RingSystemSections defines the number of segments in which ring
#   systems are rendered. The default value is 100.
#
#   ShadowTextureSize defines the size* of shadow texture to be used.
#   The default value is 256. Maximum useful value is 2048.
#
#   EclipseTextureSize defines the size* of eclipse texture to be used.
#   The default value is 128. Maximum useful value is 1024.
#
#   * The ShadowTextureSize and EclipseTextureSize values should both be
#     powers of two (128, 256, 512, etc.). Using larger values will
#     reduce the jagged edges of eclipse shadows and shadows on planet
#     rings, but it will decrease the amount of memory available for
#     planet textures.
#------------------------------------------------------------------------
  OrbitPathSamplePoints  100
  RingSystemSections     100

  ShadowTextureSize      256
  EclipseTextureSize     128

# Orbit rendering parameters
#------------------------------------------------------------------------
# OrbitWindowEnd ->
# End of the orbit window relative to the current simulation time.
# Units are orbital periods. The default value is 0.5.
# The range of values 0.0 - 1.0.
#
# OrbitPeriodsShown ->
# Number of orbit periods shown.
# The default value is 1.0.
#
# LinearFadeFraction ->
# Fraction of the window over which the orbit fades from opaque
# to transparent. Fading is disabled when this value is zero.
# The default value is 0.0. The range of values 0.0 - 1.0.
#------------------------------------------------------------------------
  OrbitWindowEnd         0.0
# OrbitPeriodsShown      1.0
  LinearFadeFraction     0.8


#-----------------------------------------------------------------------
# Set the level of multisample antialiasing.  Not all 3D graphics
# hardware supports antialiasing, though most newer graphics chipsets
# do.  Larger values will result in smoother edges with a cost in
# rendering speed.  4 is a sensible setting for recent, higher-end
# graphics hardware; 2 is probably better mid-range graphics.  The
# default value is 1, which disables antialiasing.
# AntialiasingSamples        4


#------------------------------------------------------------------------
# The following line is commented out by default.
#
# Celestia enables and disables certain rendering features based on
# the set of extensions supported by the installed OpenGL driver and 3D
# graphics hardware.  With IgnoreGLExtensions, you may specify a list of
# extensions that Celestia will treat as unsupported.  This is useful
# primarily for the developers of Celestia.
#------------------------------------------------------------------------
# IgnoreGLExtensions [ "GL_ARB_vertex_program" ]

# are projected and what distortion method is used.
# Available options for ProjectionMode are `perspective` (default) and
# `fisheye`. Available `ViewportEffect`s (distortion methods) are `none`
# (default), `passthrough`, and `warpmesh`.
# For `warpmesh` viewport effect, you need to specify a warp mesh file
# under the parameter name `WarpMeshFile`, The file should be placed
