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 Win-
dows)
• export animation as a series of images, animated GIF, AVI or
SWF
• choose format of time labels in case of animating maps with ab-
solute 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.im-
age 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 an-
imation
• 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 simpli-
fied 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"`
