.SH DESCRIPTION
|
||
|
|
\%\f3gluCylinder\fP draws a cylinder oriented along the \f2z\fP axis. The base of the cylinder
|
||
|
|
is placed at \f2z\fP = 0, and the top at $ z ~=~ "height" $. Like a sphere,
|
||
|
|
a cylinder is subdivided around the \f2z\fP axis into slices, and along the
|
||
|
|
\f2z\fP axis into stacks.
|
||
|
|
.P
|
||
|
|
Note that if \f2top\fP is set to 0.0, this routine generates a cone.
|
||
|
|
.P
|
||
|
|
If the orientation is set to \%\f3GLU_OUTSIDE\fP
|
||
|
|
(with \%\f3gluQuadricOrientation\fP), then any generated normals
|
||
|
|
point away from the \f2z\fP axis. Otherwise, they point toward the
|
||
|
|
\f2z\fP axis.
|
||
|
|
.P
|
||
|
|
If texturing is turned on (with \%\f3gluQuadricTexture\fP), then texture
|
||
|
|
coordinates are generated so that \f2t\fP ranges linearly from 0.0
|
||
|
|
at \f2z\fP = 0 to 1.0 at \f2z\fP = \f2height\fP, and \f2s\fP
|
||
|
|
ranges from 0.0 at the +\f2y\fP axis, to 0.25 at the +\f2x\fP axis,
|
||
|
|
to 0.5 at the -\f2y\fP axis, to 0.75 at the \-\f2x\fP axis,
|
||
|
|
and back to 1.0 at the +\f2y\fP axis.
