A three dimensional shape with two flat ends that are circular. The cylinder has the same cross-section from one end to the other.

Learn about cylinders at MathIsFun.com

The 'radius' specifies the circular size about the Z axis, while the 'height' specifies the size. The 'segments' specify the number of segments to create per full rotation.

Defaults:

• radius : 1
• height : 2
• center : [0, 0, 0]
• segments : 32

cylinder({r: 1, h: 10})
cylinder({r: 1, h: 10, center: true})   // default: center:false
cylinder({r: 1, h: 10, center: [true, true, false]})
cylinder({r: 1, h: 10, round: true})
cylinder({r1: 3, r2: 0, h: 10})
cylinder({start: [0,0,0], end: [0,0,10], r1: 1, r2: 2, fn: 50})

The CSG library functions can also be used. NOTE: Deprecated in the V2 API

CSG.cylinder({
  start: [0, -1, 0],
  end: [0, 1, 0],
  radius: 1,                        // true cylinder
  resolution: 16
});
 
CSG.cylinder({
  start: [0, -1, 0],
  end: [0, 1, 0],
  radiusStart: 1,                   // start- and end radius defined, partial cones
  radiusEnd: 2,
  resolution: 16
});
 
CSG.roundedCylinder({               // and its rounded version
  start: [0, -1, 0],
  end: [0, 1, 0],
  radius: 1,
  resolution: 16
});
