NAME

gleToroid - Generalized torus, lathe with circle contour.

SYNTAX

void gleToroid (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 gleLathe, except contour is a circle. Uses gleLathe to draw.
