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"`
