The space property of the XRCylinderLayer interface represents the layer's spatial relationship with the user's physical environment.
The XRWebGLBinding.createCylinderLayer() method creates a cylinder layer and requires a space property to be provided. The XRCylinderLayer.space property can be used after layer creation to get the space used or to set it to a new one.
const cylinderLayer = xrGlBinding.createCylinderLayer({
space: xrReferenceSpace,
viewPixelWidth: 512,
viewPixelHeight: 512,
});
cylinderLayer.space = someOtherSpace;
