- .SH DESCRIPTION
- glutSpaceballMotionFunc sets the Spaceball motion callback for
- the current window. The Spaceball motion 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 translations.
- The x, y, and z callback parameters indicate the translations along the X,
- Y, and Z axes. The callback parameters are normalized to be within the
- range of -1000 to 1000 inclusive.
- Registering a Spaceball motion callback when a Spaceball device is not
- available has no effect and is not an error. In this case, no Spaceball
- motion callbacks will be generated.
- Passing NULL to glutSpaceballMotionFunc disables the generation
- of Spaceball motion callbacks. When a new window is created, no
- Spaceball motion callback is initially registered.
