DESCRIPTION

       The Animation Tool is a wxGUI component for animating series of GRASS raster or vector maps or space time
       datasets (created by t.* modules).

       Animation Tool allows you to:

           •   display up to 4 synchronized animations

           •   each animation can consist of base map layer(s) and (multiple) series  in  arbitrary  order  (for
               example, raising water level with elevation)

           •   control the animation speed

           •   interactively change active frame using a slider

           •   visualize space time datasets with unequally spaced intervals

           •   animate 3d view (partially implemented, not supported on Windows)

           •   export animation as a series of images, animated GIF, AVI or SWF

           •   choose format of time labels in case of animating maps with absolute time

           •   choose background color

           •   set  starting and ending region in order to change region during animation (alternatively you can
               set N-S/E-W values instead of the ending region; these are used for making the region smaller  or
               larger for each step)

       3D  view  animation enables to animate raster (as an elevation map or a color map) or vector map (points,
       lines). Internally, module m.nviz.image is used.  To display 3D view animation follow these steps:

           •   open GRASS GUI, load maps and start 3D view

           •   set view, light and other parameters as you like

           •   save workspace file

           •   add new animation in Animation Tool, choose 3D view mode

           •   choose data (series of maps or space time dataset) used for animation

           •   set workspace file

           •   choose parameter (parameter of m.nviz.image) to animate (e.g. color_map)

NOTE

       The Animation Tool follows the computational region settings, so please be sure your computational region
       is  set  to  the  geographic  extent  of maps you are animating.  You can change the computational region
       (using g.region) and then reload the maps to update the animation.

EXAMPLES

       g.gui.animation raster=rmap1,rmap2,rmap3
       g.gui.animation vector=vmap1,vmap2,vmap3
       g.gui.animation strds=precipitation_2000_2010
       The loading of a series of maps into the Animation Tool can be simplified with g.list (back ticks  syntax
       works for Linux and Mac only):
       g.gui.animation raster=`g.list type=raster mapset=. separator=comma pattern="precip*"`
       Using  extended  regular  expressions, the list of a series of raster maps can be subset by e.g., numeric
       range (here: precipitation for the years 1997-2012):
       g.gui.animation raster=`g.list -e type=raster mapset=. separator=comma pattern="precip_total.(199[7-9]|200[0-9]|201[0-2]).sum"`
