SYNTAX

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