SYNTAX

void gleHelicoid (gleDouble rToroid,
                  gleDouble up[3],
                  gleDouble startRadius,
                  gleDouble drdTheta,
                  gleDouble startZ,

                  gleDouble startXform[2][3],
                  gleDouble dXformdTheta[2][3],
                  gleDouble startTheta,
                  gleDouble sweepTheta);

ARGUMENTS

rToroid
circle contour (torus) radius
startRadius
spiral starts in x-y plane
drdTheta
change in radius per revolution
startZ
starting z value
dzdTheta
change in Z per revolution
startXform
starting contour affine transformation
dXformdTheta

DESCRIPTION

Generalized Torus. Similar to gleSpiral, except contour is a circle. Uses gleSpiral to draw.
