Departure

  E - DEPARTURE
  AmigaOS4 port (c) kas1e
  =======================

  ABOUT
  -----

  E - Departure is another 64 kB intro created by the French  demoscene group
  Ctrl-Alt-Test. The released intro is actually only about 38 kB in size.

  The  intro was  released in  December 2010  and  presented at  The Ultimate
  Meeting 2010, where it placed fourth in the 64 kB intro competition.

  Original credits  are Pierre "Cyborg Jeff" Martin  (music),  Julien "Zavie"
  Guertault (code), and Laurent "LLB" Le Brun (code).


  AMIGAOS4 PORT
  -------------

  The port  retains the  original desktop  OpenGL renderer,  both MRT  colour
  attachments, the velocity buffer, glow, and motion-blur passes.

  All 55  original vertex  and fragment  shaders are  embedded byte-for-byte.

  The OS4 executable uses  SDL2 (statically linked into the binary) with Mesa
  and requests an OpenGL 3.3 compatibility-profile context. Its Win32 window,
  input, timing,  audio, and font  code was replaced with  portable versions,
  together with the required PowerPC big-endian fixes.

  The original  "telescope.v2m" soundtrack  is embedded and rendered  live by
  the portable V2  synthesizer through  SDL2. The TrueType  font is  embedded
  too, so  no external data  files are required.  If SDL2  cannot  initialize
  audio, the intro continues without sound.

  And, you can see the FPS in the window title when running in windowed mode.


  COMMAND-LINE OPTIONS
  --------------------

  Usage:

      Departure [options]

  Options:

      --windowed
      --window
      --win
          Start in a window. Fullscreen desktop mode is used by default.

      --width N
          Set the startup and internal rendering width.
          Default: 1280

      --height N
          Set the startup and internal rendering height.
          Default: 720

      --motionblur_disable
          Use the final pass without motion blur.

      --mrt_disable
          Disable the velocity-buffer MRT path.

      --help
      -h
          Display the command-line help and exit.

  The two diagnostic  options can be used  independently or together. Without
  them, the complete original desktop OpenGL rendering path remains enabled.
