Details

Animations can be created in a loop modifying the scene and saving each screenshot to a file. Various graphics programs (e.g. ImageMagick) can put these together into a single animation. (See movie3d or the example below.)

Note

On some systems, the snapshot will include content from other windows if they cover the active rgl window. Setting top=TRUE (the default) will use rgl.bringtotop before the snapshot to avoid this. (See http://www.opengl.org/resources/faq/technical/rasterization.htm#rast0070 for more details.)
