Parameters
qobj
The quadric
object (created with gluNewQuadric).
baseRadius
The radius of
the cylinder at z = 0.
topRadius
The radius of
the cylinder at z = height.
height
The height of
the cylinder.
slices
The number of
subdivisions around the z-axis.
stacks
The number of
subdivisions along the z-axis.
Remarks
The gluCylinder function 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.
Notice that if topRadius is set to zero, then
this routine will generate 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):
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
positive y-axis, to 0.25 at the positive x-axis, to 0.5 at the negative y-axis,
to 0.75 at the positive x-axis, and back to 1.0 at the positive y-axis.
