The radius property of the XRCylinderLayer interface represents the radius of the cylinder.

A number representing the radius of the cylinder.

The XRWebGLBinding.createCylinderLayer() method creates a cylinder layer and allows to specify a radius. The XRCylinder.radius property can be used after layer creation to get the radius used or to set it to a new one.

const cylinderLayer = xrGlBinding.createCylinderLayer({
  space: xrReferenceSpace,
  viewPixelWidth: 1200,
  viewPixelHeight: 600,
  centralAngle: (60 * Math.PI) / 180,
  aspectRatio: 2,
  radius: 2,
  transform: new XRRigidTransform(/* … */),
});

cylinderLayer.radius; // 2
