gluCylinder
NAME
gluCylinder -- draw a cylinder
C SPECIFICATION
void gluCylinder(GLUquadricObj *qobj,
GLdouble baseRadius,
GLdouble topRadius,
GLdouble height,
GLint slices,
GLint stacks)
PARAMETERS
- qobj
-
Specifies the quadrics object (created with
gluNewQuadric).
- baseRadius
-
Specifies the radius of the cylinder at z = 0.
- topRadius
-
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 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), 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.
