gleScrew(3) 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.
