DESCRIPTION

       This manual page documents opencity command.

OPTIONS

                 -fs | --fullscreen
                 Enable fullscreen mode

                 -glv | --gl-version
                 Show the information of the current  available  OpenGL  implementation  on  your
                 machine then quit

                 -dd | --data-dir newDataPath
                 Specify   to   new   path   to   OpenCity's   data.   For   example:  --data-dir
                 /home/foo/bar/share/opencity/

                 -cd | --conf-dir newConfigPath
                 Specify to  new  path  to  OpenCity's  configuration.  For  example:  --conf-dir
                 /home/foo/bar/etc/opencity/

                 -na | --no-audio
                 Disable the audio system

                 --generator-height-map heightMapPicture
                 Load  a  gray-level  picture  as height map (PNG). The water level is gray level
                 128, each map level is one gray level. That's why the whole picture seems to  be
                 in  a  medium  gray, because there's only a minor difference between the pixels.
                 You can draw yourself the height-map or  generate  from  any  map  sources.  The
                 interesting  data for this work are the DEM satellite data. The map generator in
                 OpenCity will crop the picture if it's too big.

                 --generator-seed seed
                 The seed is the random integer seed used by the map generator

                 --generator-map MAP-TYPE
                 MAP-TYPE: 0=plain (default), 1=hill, 2=mountain

                 --generator-water WATER-TYPE
                 WATER-TYPE: 0=dry, 1=lake (default), 2=coast

                 --generator-map-shape MAP-SHAPE-TYPE
                 MAP-SHAPE-TYPE: 0=none (default), 1=island, 2=volcano, 3=crater

                 --generator-tree-density TREE-DENSITY-TYPE
                 TREE-DENSITY-TYPE: 0=sparse (default), 1=normal, 2=dense
