gleHelicoid : PyOpenGL 3.1.4 GLE Man Pages

Generalized torus, spiral with circle contour.

Signature

gleHelicoid( gleDouble( rToroid ) , gleDouble[3]( up ) , gleDouble( startRadius ) , gleDouble( drdTheta ) , gleDouble( startZ ) , gleDouble( dzdTheta ) , gleDouble[2][3]( startXform ) , gleDouble[2][3]( dXformdTheta ) , gleDouble( startTheta ) , gleDouble( sweepTheta ) )-> void

gleHelicoid( rToroid , startRadius , drdTheta , startZ , dzdTheta , startXform , dXformdTheta , startTheta , sweepTheta )

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

Parameters

Variables	Description
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.
