The GRASS GTK+ GUI Animation Output

The GTK+ GRASS Interface 3D View lets the user save a keyframe animation directly to a supported animation format. The 3D view uses the GRASS ogsf library to render an animation. If the GRASS ogsf library has been built with the optional FFMPEG library, movies can be directly rendered to any supported format.

Animation Save DialogIf FFMPEG support is not available, the animation can be saved as individual images.

By default, the animation is rendered off-screen. The user can optionally turn this off and render the animation in the current 3D View. The advantage of off-screen rendering is that other windows and screen-savers do not interfere with the saved animation.

The animation dialog shows the rendering progress by frame number.
