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

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

gleSpiral, gleHelicoid
