XRCylinderLayer: centralAngle property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The centralAngle property of the XRCylinderLayer interface represents the angle in radians of the visible section of the cylinder.

Value

A number representing the angle in radians of the visible section of the cylinder.

Examples

Getting a layer's central angle

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

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

cylinderLayer.centralAngle; // 1.0471975511965976
