PARAMETERS

quad: Specifies the quadrics object (created with gluNewQuadric).
base: Specifies the radius of the cylinder at z = 0.
top: Specifies the radius of the cylinder at z = height.
height: Specifies the height of the cylinder.
slices: Specifies the number of subdivisions around the z axis.
stacks: Specifies the number of subdivisions along the z axis.

DESCRIPTION

gluCylinder draws a cylinder oriented along the z axis. The base of the cylinder is placed at z = 0, and the top at $ z ~=~ "height" $. Like a sphere, a cylinder is subdivided around the z axis into slices, and along the z axis into stacks. Note that if top is set to 0.0, this routine generates a cone. If the orientation is set to GLU_OUTSIDE (with gluQuadricOrientation), then any generated normals point away from the z axis. Otherwise, they point toward the z axis. If texturing is turned on (with gluQuadricTexture), then texture coordinates are generated so that t ranges linearly from 0.0 at z = 0 to 1.0 at z = height, and s ranges from 0.0 at the +y axis, to 0.25 at the +x axis, to 0.5 at the -y axis, to 0.75 at the -x axis, and back to 1.0 at the +y axis.
