Mirror Engine API / CylinderGeometry
Class: CylinderGeometry
A procedural cylinder-shaped geometry.
The size, shape and tesselation properties of the cylinder can be controlled via constructor parameters. By default, the function will create a cylinder standing vertically centered on the XZ-plane with a radius of 0.5, a height of 1.0, 1 height segment and 20 cap segments.
Note that the cylinder is created with UVs in the range of 0 to 1.

Constructors
new CylinderGeometry()
new CylinderGeometry(opts?: {
calculateTangents: boolean;
capSegments: number;
height: number;
heightSegments: number;
radius: number;
}): CylinderGeometry
Create a new CylinderGeometry instance.
Parameters
opts?
An object that specifies optional inputs for the function as follows:
calculateTangents?
boolean
Generate tangent information (defaults to false).
capSegments?
number
The number of divisions around the tubular body of the cylinder (defaults to 20).
height?
number
The length of the body of the cylinder (defaults to 1.0).
heightSegments?
number
The number of divisions along the length of the cylinder (defaults to 5).
radius?
number
The radius of the tube forming the body of the cylinder (defaults to 0.5).
