tour.
SYNTAX
void gleHelicoid (gleDouble rToroid,
gleDouble up[3],
gleDouble startRadius,
gleDouble drdTheta,
gleDouble startZ,
gleDouble dzdTheta,
gleDouble startXform[2][3],
gleDouble dXformdTheta[2][3],

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
tangent change xform per revolution
startTheta
start angle in x-y plane
sweepTheta
degrees to spiral around
DESCRIPTION
Generalized Torus. Similar to gleSpiral, except contour is
a circle. Uses gleSpiral to draw.
