NAME

       castle-model-viewer - Viewer for 3D and 2D models, like glTF, X3D, VRML and more

SYNOPSIS

       castle-model-viewer [OPTION]... [FILE]

DESCRIPTION

       castle-model-viewer is a viewer for 3D and 2D model formats supported by Castle Game Engine: glTF, X3D,
       VRML, MD3, OBJ, STL, Collada, Spine JSON, sprite sheets and more.

       Supports viewing the scene in the "Examine" mode and walking in the virtual world with collision
       detection and gravity. Many 3D graphic effects are available like mirrors, shadows, shaders. We can also
       convert between some model formats.

       Full documentation is available online at https://castle-engine.io/castle-model-viewer.

OPTIONS

       -h, --help
           Print the help message and exit.

       -v, --version
           Print the version number and exit.

       -H / --hide-extras
           Do not show anything extra (like status text or toolbar or bounding box) when program starts. Show
           only the loaded model.

       --screenshot TIME IMAGE-FILE-NAME
           Take a screenshot of the loaded scene at given TIME, and save it to IMAGE-FILE-NAME. You most
           definitely want to pass 3D model file to load at command-line too, otherwise  we’ll just make a
           screenshot of the default black scene.

       --screenshot-range TIME-BEGIN TIME-STEP FRAMES-COUNT FILE-NAME
           Take a FRAMES-COUNT number of screenshots from TIME-BEGIN by step TIME-STEP. Save them to a single
           movie file (like .avi) (ffmpeg must be installed and available on $PATH for this) or to a sequence of
           image files (FILE-NAME must then be specified like image@counter(4).png).

       --viewpoint NAME
           Use the viewpoint with given name or index as initial. Especially useful to make a screenshot from
           given viewpoint.

       Use full-screen anti-aliasing. Argument AMOUNT is an integer >= 0. Exact 0 means "no anti-aliasing", this
       is the default. Each successive integer generally makes method one step better. Especially useful to make
       a screenshot with anti-aliasing quality.

       --audio-device DEVICE-NAME
           Choose specific OpenAL audio device. See the available device names in the --help output, or in the
           "Preferences → Sound Device" menu.

       --no-sound
           Turn off sound.

WINDOW OPTIONS

       --geometry WIDTHxHEIGHT<sign>XOFF<sign>YOFF
           Set initial window size and/or position.

       --fullscreen
           Set initial window size to cover whole screen.

       --fullscreen-custom WIDTHxHEIGHT
           Try to resize the screen to WIDTHxHEIGHT and then set initial window size to cover whole screen.

       --display DISPLAY-NAME
           Use given X display name.
