<h2>DESCRIPTION</h2>

The <b>Animation Tool</b> is a <em><a href="wxGUI.html">wxGUI</a></em> component
for animating a series of GRASS raster maps or a space time raster dataset (created by t.* modules).

<p>
Animation Tool allows you to:

<ul>
  <li>display up to 4 synchronized animations</li>
  <li>control the animation speed</li>
  <li>interactively change active frame using a slider</li>
  <li>visualize space time datasets with unequally spaced intervals</li>
  <li>animate 3d view (partially implemented)</li>
</ul>

<p>
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:
<ul>
  <li>open GRASS GUI, load maps and start 3D view</li>
  <li>set view, light and other parameters as you like</li>
  <li>save workspace file</li>
  <li>add new animation in Animation Tool, choose 3D view mode</li>
  <li>choose data (series of maps or space time dataset) used for animation</li>
  <li>set workspace file</li>
  <li>choose parameter (parameter of m.nviz.image) to animate (e.g. color_map)</li>

</ul>

<h2>NOTE</h2>
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 <a href="g.region.html">g.region</a>)
and then reload the maps to update the animation.

<h2>TODO</h2>
<ul>
  <li>export animation</li>
  <li>...</li>
</ul>
