NAME

gleScrew - Draws screw-type shapes.

SYNTAX

void gleScrew (int ncp,
               gleDouble contour[][2],
               gleDouble cont_normal[][2],
               gleDouble up[3],
	       gleDouble startz,
	       gleDouble endz,
	       gleDouble twist);

ARGUMENTS

ncp: number of contour points
contour: 2D contour
cont_normal: 2D contour normals
up: up vector for contour
startx: start of segment
endz: end of segment
twist: number of rotations

DESCRIPTION

Draws screw-type shapes. Takes a contour, and extrudes it along the z-axis, from a start z value of startz to an end z-value of endz. During the extrusion, it will spin the contour along the contour origin by twist degrees.
