Sweeperis an interactive program that lets the user generate
interesting surfaces by specifying a profile curve and a sweep
curve (trajectory). The profile curve is swept along the path of
the sweep curve to produce a surface. First, you should check
out an example solution by clicking here or running the program
in /cse/courses/cse457/bin/sweeper. The program has three panes:
the top pane is for the surface, the lower left pane is for the
profile curve, and the lower right pane is for the sweep path.
Click four points in the profile pane to start with. Then click
four points in the sweep pane. You should now see some sort of
surface appearing in the surface pane on top. You can move
around in the 3D windows when in viewing mode by using the left
and middle mouse buttons in different combinations, as described
below. The menu brought up by the right mouse button has a few
other useful features. Selecting "home" under the "Functions"
menu will reset the 3D view. Selecting "hidden line" under the
"Draw Style" m
