NAME
sweep - Geomview external module for creating surfaces of
extrusion and rotation.
SYNOPSIS
sweep
DESCRIPTION
Sweep is a tool used to make surfaces of extrusion and
rotation out of geomview vect objects. Sweep is intended to
run as a geomview external module. It uses the target
object, which must be a vect, to create the surfaces. To
create the surface, press the button marked "Make Sweep" at
the bottom of the panel. The program will create the
surface and automatically send it to geomview as a new
object named "sweep."
The two buttons at the top of the sweep panel control the
type of sweep. If the button marked "Translational Sweep"
is pressed, the target object will be used to make a surface
of extrusion. The fields marked "Length of sweep" and
"Direction of sweep" are used to control the attributes of
the surface.
If the button at the top of the panel marked "Rotational
Sweep" is pressed, the surface formed will be the surface of
the rotation of the vect. The box in the middle of the
panel will be replaced by a box with controls for the
attributes of the surface of rotation. Note that the sweep
may be of an arbitrary length around an arbitrary vector.
The field marked "Arc length" controls the length of the
sweep in degrees or radians. The fields marked "End of
axis" and "Direction axis" are used to specify the axis
around which the vect will be rotated. The field marked
"Divisions" is used to specify the number of pieces into
which the sweep will be radially divided. A higher number
will give a smoother appearance.
