gleHelicoid( gleDouble(rToroid), gleDouble(startRadius), gleDouble(drdTheta), gleDouble(startZ), gleDouble(dzdTheta), arrays.GLdoubleArray(startXform), arrays.GLdoubleArray(dXformdTheta), gleDouble(startTheta), gleDouble(sweepTheta) ) -> None

Parameters

VariablesDescription
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.
