"Two Hands are Better Than One"
SpaceBall®
4000
To take a close look at something in the
real world, you pick it up and examine it from every angle.
It's so natural, you don't even think about it. Now working
in 3D is just this intuitive. With the SpaceBall®
4000, you can intuitively zoom, pan and rotate
models, exploring and navigating your designs as naturally
as if they were objects in the real world
.

SpaceBall® 4000 is
as essential a tool as your mouse or keyboard, giving you
the ability to manipulate 3D objects on the screen, while
simultaneously controlling 3D camera angles and positions
for viewing those objects. It’s a much more natural,
free-flowing way to work. If you use a common interface,
executing even simple moves requires a decision, then
keystrokes and/or mouse clicks. This interrupts your natural
motion, slowing you down and actually restricting you from
attempting more complete or continuous motion. But, the
greater flexibility and interactivity of a 3D motion
controller makes even difficult moves easy. You're free to
go farther and be even more creative.

Place your fingers gently
on the controller's ball. The ball senses pressure you apply
to it - pushes, pulls and twists - and uses that information
to correspondingly move your model, camera or eye point on
the screen. Pull up or push down to move your model, camera
or eye point up or down. Push left or right to move your
model left or right. Pull towards you or push away to move
your model nearer or farther away. Orient your model on the
screen by simply twisting in any direction to rotate it
around the X, Y or Z axis (pitch, roll, yaw)

You will quickly be able
to combine all movements and control your 3D models with six
degrees of freedom. The amount of pressure you apply
controls speed of movement. A light touch moves your models
slowly and accurately; just increase pressure to increase
speed. It will be like holding your model in your hand -
interacting in
3D as you do in the real world.
