gluCylinder.3gl

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.
