EXAMINER VIEWER
The left, right and bottom edges of the examiner viewer contain a
variety of thumb wheels and buttons that can be used to adjust
the visualization of the 3D scene. The Rotx and Roty thumb
wheels allow the user to rotate the scene about the x and y axes,
respectively. The dolly thumb wheel moves the virtual camera
closer and further from the scene allowing the user to examine
specific parts in detail or view the entire scene. On the right
edge of the viewer are eight buttons which affect the way the
user can interact with the scene.
Pointer
Changes the cursor to a pointer which allows blocks to be
selected in the scene. See the Metric Selection section
below.
Hand
Changes the cursor to a hand which allows the scene to be
rotated, translated and dollied using a combination of mouse
buttons. The left mouse button can be used to rotate the
scene in the direction of the mouse. Releasing the left
mouse button before the mouse has stopped moving will cause
the scene to continue to rotate, which can be stopped by
pressing the left mouse button again. The middle mouse
button will ``pan'' the scene, and both mouse buttons act as
a dolly for the virtual camera.
Question Mark
Displays the SGI Help information for the examiner viewer.
Home
Changes the scene back to its original position, unless the
home position has been changed by the home pointer button.
Home Pointer
Changes the home position of the scene to be the scene
currently in view.
Eye Resizes the scene so that it completely fits into the 3D
viewing area.
Cross-hairs
Moves the object under the cursor to the center of the
viewing area, if the hand cursor has been selected. Pressing
the ``s'' key while the cursor is over an object has the same
effect.
Perspective Box
Switches the display between perspective and orthogonal
projections.
Pressing the right mouse button within the scene window will
bring up a menu of options which affect how the 3D scene is
drawn. The options include drawing the blocks as wire frames,
and turning on stereo viewing.
