DESCRIPTION

46       The  Animation  Tool is a wxGUI component for animating series of GRASS
47       raster or vector maps or space time datasets (created by t.* modules).
48
49       Animation Tool allows you to:
50
51           ·   display up to 4 synchronized animations
52
53           ·   each animation can consist of base map layer(s) and  (multiple)
54               series  in  arbitrary  order  (for example, raising water level
55               with elevation)
56
57           ·   control the animation speed
58
59           ·   interactively change active frame using a slider
60
61           ·   visualize space time datasets with unequally spaced intervals
62
63           ·   animate 3d view (partially implemented, not supported  on  Win‐
64               dows)
65
66           ·   export  animation  as  a series of images, animated GIF, AVI or
67               SWF
68
69           ·   choose format of time labels in case  of  animating  maps  with
70               absolute time
71
72           ·   choose background color
73
74           ·   set starting and ending region in order to change region during
75               animation (alternatively you can set N-S/E-W values instead  of
76               the ending region; these are used for making the region smaller
77               or larger for each step)
78
79       3D view animation enables to animate raster (as an elevation map  or  a
80       color   map)   or   vector  map  (points,  lines).  Internally,  module
81       m.nviz.image is used.  To display 3D view animation follow these steps:
82
83           ·   open GRASS GUI, load maps and start 3D view
84
85           ·   set view, light and other parameters as you like
86
87           ·   save workspace file
88
89           ·   add new animation in Animation Tool, choose 3D view mode
90
91           ·   choose data (series of maps or space  time  dataset)  used  for
92               animation
93
94           ·   set workspace file
95
96           ·   choose  parameter  (parameter of m.nviz.image) to animate (e.g.
97               color_map)
98

NOTE

100       The Animation Tool follows the computational region settings, so please
101       be  sure  your  computational region is set to the geographic extent of
102       maps you are animating.  You can change the computational region (using
103       g.region) and then reload the maps to update the animation.
104

EXAMPLES

106       g.gui.animation raster=rmap1,rmap2,rmap3
107       g.gui.animation vector=vmap1,vmap2,vmap3
108       g.gui.animation strds=precipitation_2000_2010
109       The  loading of a series of maps into the Animation Tool can be simpli‐
110       fied with g.list (back ticks syntax works for Linux and Mac only):
111       g.gui.animation raster=`g.list type=raster mapset=. separator=comma pattern="precip*"`
112       Using extended regular expressions, the list of a series of raster maps
113       can be subset by e.g., numeric range (here: precipitation for the years
114       1997-2012):
115       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"`
