The read-only ignoreDepthValues property of the XRProjectionLayer interface is a boolean indicating if the XR compositor is not making use of depth buffer values when rendering the layer.

A boolean. true indicates the XR compositor doesn't make use of depth buffer values; false indicates the content of the depth buffer will be used when rendering the layer.

If the depthFormat option is 0 when creating a projection layer, the ignoreDepthValues property will be true. See also XRWebGLBinding.createProjectionLayer().

let glProjectionLayer = xrGLBinding.createProjectionLayer({
  depthFormat: 0,
});

glProjectionLayer.ignoreDepthValues; // true
