XRCylinderLayer: centralAngle property

{{APIRef("WebXR Device API")}}{{SeeCompatTable}}

The centralAngle property of the {{domxref("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 {{domxref("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.

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
