Description
glutSpaceballRotateFunc
sets the Spaceball rotate callback for the current window. The Spaceball
rotate callback for a window is called when the window has Spaceball input focus (normally, when the mouse is in the
window) and the user generates Spaceball rotations. The
x
,
y
, and
z
callback parameters indicate the
rotation along the X, Y, and Z axes. The callback parameters are normalized to be within the range of -1800 to 1800
inclusive.
Registering a Spaceball rotate callback when a Spaceball device is not available is ineffectual and not an error. In
this case, no Spaceball rotate callbacks will be generated.
Passing
NULL
to
glutSpaceballRotateFunc
disables the generation of Spaceball
rotate callbacks. When a new window is created, no Spaceball rotate callback is initially registered.
