Joystick-Mode Interaction
In
joystick-mode interaction, the speed and direction of zooming, rotation, and
panning are determined by the position of the cursor relative to the center
of the display area.
- When the cursor is far from the center, interaction is faster.
- When the cursor is near the center of the display area, interaction is slower.
- To zoom in, place the cursor on the upper half of the display area, then
press and hold the right mouse button. To end zooming, release the button.
- To zoom out, place the cursor on the lower half of the display area, then
press and hold the right mouse button. To end zooming, release the button.
- To rotate, place the cursor such that its position relative to
the display area center indicates the direction of rotation, then press and hold
the left mouse button. To end rotation, release the button.
- To rotate around an axis perpendicular to the screen, place the cursor such that its position
relative to the display area center indicates the direction of rotation, then press and
hold the Ctrl key and left mouse button. To end rotation, release the button.
- To pan, place the cursor such that its position relative to the display area
center indicates the direction of panning, hold down the Shift key,
then press and hold the left mouse button. To end panning,
release the button.
