Arch , Flow , Heme , Jet, and Shuttle
arch is a simulated architectural model in which the eye perceives a 3D
environment. One building (the white one) is always displayed. Several other
buildings can be displayed in wireframe or as solid objects.
Once you select a window for input, you interact with the program through
both the keyboard and the mouse. Each mouse button or combination of
mouse buttons causes a different motion of the eye within the environment.
The
F
key toggles the other buildings;
S
toggles the polygon fill on the
buildings. The
M
key starts a constant motion that continues even after the
window is no longer selected for input (detached).
flow is an array of nearly 20,000 data points in a frame. The data was calculated
at NASA-Ames Research Center on the Illiac-IV computer. flow presents some
solutions to the Navier-Stokes equations for flow in a turbulent fluid.
LEFTMOUSE controls viewer altitude and azimuth. MIDDLEMOUSE controls
distance and twist (rotation on the z-axis). RIGHTMOUSE starts a sequence of
small rotations. The sequence continues even if the window is detached.
heme is a depth-cued molecular model comprised of 1022 points and 549
vectors. It is controlled by a popup menu. To see the menu, hold down
MIDDLEMOUSE. To select or de-select an entry, position the cursor on the
entry and press and release LEFTMOUSE. Two menus appear. The left
column of menu entries independently turns off and on each of the five parts
of the molecule. The right column of menu entries controls the
transformations of the molecule. The menu entries in the right column are
graphical icons.
A LEFTMOUSE press changes the color of a menu entry and starts that
motion. Another LEFTMOUSE press restores the initial state. Simultaneously
specified opposite motions cancel each other out, leaving no motion in the
specified direction. The
ENTER
or
M
key causes current motion to continue
even after the program’s window is detached.
The bungalow icon (shaped like a house) resets the program back to the center
of the window (especially helpful if the molecule has been dragged out of
sight). The stop sign icon exits the program and cancels the window.
jet is a wireframe model of a fighter plane. The image includes 660 vectors and
can be displayed with constant intensity or depth-cuing. Pressing one of the
three mouse buttons enables rotation about one of the three axes. The amount
of rotation is determined by the left-to-right motion of the mouse. Other
combinations of mouse buttons allow x-y translation controlled by the mouse
and scaling at fixed positive and negative rates. The
ENTER
button enables and
disables depth-cueing. Press
M
to start or stop a continuous motion that
continues after the window is detached.
