A class for generating cylinder geometries

Code Example

const geometry = new v3d.CylinderGeometry(5, 5, 20, 32); const material = new v3d.MeshBasicMaterial({color: 0xffff00}); const cylinder = new v3d.Mesh(geometry, material); scene.add(cylinder);


CylinderGeometry(radiusTop : Float, radiusBottom : Float, height : Float, radialSegments : Integer, heightSegments : Integer, openEnded : Boolean, thetaStart : Float, thetaLength : Float)

radiusTop — Radius of the cylinder at the top. Default is 1.
radiusBottom — Radius of the cylinder at the bottom. Default is 1.
height — Height of the cylinder. Default is 1.
radialSegments — Number of segmented faces around the circumference of the cylinder. Default is 8
heightSegments — Number of rows of faces along the height of the cylinder. Default is 1.
openEnded — A Boolean indicating whether the ends of the cylinder are open or capped. Default is false, meaning capped.
thetaStart — Start angle for first segment, default = 0 (three o'clock position).
thetaLength — The central angle, often called theta, of the circular sector. The default is 2*Pi, which makes for a complete cylinder.


See the base Geometry class for common properties.

.parameters : Object

An object with a property for each of the constructor parameters. Any modification after instantiation does not change the geometry.
