I/O for Three Dimensions
A machine can't do anything for you unless you have some way of entering and
extracting information from it. Here are some possibilities for the 3D world.
Mouse/Keyboard:
The classic interface with a computer. The system work for
the 2D environment where lateral movement is all that is required for efficient
interface. Early 3D rendering were done using the combination, either by
coordinate system or by combinational movements.
3D Trackball:
AKA the spaceball, this futuristic looking device responds to
pressure, push, pull, slide, drag but does not physically move like the
traditional trackball. It can be used to input coordinates and control splines
in 3D.
3D Mouse:
AKA the flymouse, a wireless implement of the mouse using field
tracking systems. Such as electromagnetic or sonic tracking. As long as the
mouse is within a certain distance from the field emitting device, its path in
3D space can be followed by the computer.
Joystick:
Yeah, it's for games. But is also a series tool for 3D rendering.
Using 2 joysticks synched with one object, the graphic designer could manipulate
the model in both the XY and XZ plane.
Monitors:
Traditional CRT monitors have come a long way since its
introduction in the 1960's. From the monochrome 6 inch monitors to today's 21
inch FD Trinitron. However, CRT based technology is limited and is being
replaced by the lighter, smaller, more efficient and higher resolution (well,
eventually) active matrix LCD technology.
Force Feedback Manipulators:
It didn't take long for people to realize that
the key to designing great 3D models is to make the model real to the designer.
Thus evolved a whole category of futuristic force feedback input devices.
Gloves, hats, and even bodysuits with motors and sensors inside to make you
"feel" the object that you are working on. This is indeed the
future...
