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.
