After a LiveGraphics3D applet has successfully initialized itself the following interactions are always supported.

user action applet reaction
dragging (left mouse button pressed) rotating about an axis in the picture
releasing left mouse button while dragging spinning about an axis in the picture
SHIFT key pressed plus vertical dragging zooming
SHIFT key pressed plus horizontal dragging rotating about an axis perpendicular to the picture
CONTROL key pressed plus vertical dragging changing focal length
CONTROL key pressed plus horizontal dragging changing strength of stereo effect
META (ALT) key (or right mouse button) pressed plus vertical dragging stripping parts of the graphics
"o" key printing parameter settings to the Java console (aka Java messages window)
"s" key toggling between single picture, stereo pictures for diverge fusing and stereo pictures for cross fusing
HOME key restoring original perspective (no spinning)

The META key is usually mapped to the ALTERNATE (ALT) or COMMAND key; on some systems it is emulated by the right mouse button. The CONTROL key (CTRL) does not work with all web browsers (e.g. Safari). You might be able to use CONTROL plus right(!) mouse button instead. Rotation about an axis perpendicular to the picture is not possible if a rotating background is included.

Several additional interactions are supported for animations.

user action applet reaction
entering applet region starting animation
leaving applet region stopping animation
double clicking stopping or restarting animation
META (ALT) key (or right mouse button) pressed plus horizontal dragging switching through frames
