{{APIRef("WebXR Device API")}}{{SeeCompatTable}}
The radius property of the {{domxref("XREquirectLayer")}} interface represents the radius of the sphere.
A number representing the non-negative radius (in meters) of the sphere. Values of zero or infinity are treated as representing an infinite sphere. Setting radius to a value less than 0 will set it to 0.
The {{domxref("XRWebGLBinding.createEquirectLayer()")}} method creates an equirect layer and allows specifying a radius. The XREquirectLayer.radius property can be used after layer creation to get the radius used or to set it to a new one.
const equirectLayer = xrGlBinding.createEquirectLayer({
space: xrReferenceSpace,
viewPixelWidth: 1200,
viewPixelHeight: 600,
centralHorizontalAngle: 2 * Math.PI,
upperVerticalAngle: Math.PI / 2.0,
lowerVerticalAngle: -Math.PI / 2.0,
radius: 0,
});
equirectLayer.radius; // 0
