Each {{XRSession}} has a <dfn>minimum near clip plane</dfn> and a <dfn>maximum far clip plane</dfn>, defined in meters. The values MUST be determined by the user agent and MUST be non-negative. The [=minimum near clip plane=] SHOULD be less than <code>0.1</code>. The [=maximum far clip plane=] SHOULD be greater than <code>1000.0</code> (and MAY be infinite).

The <dfn method for="XRSession">updateRenderState(|newState|)</dfn> method queues an update to the [=active render state=] to be applied on the next frame. Unset fields of the {{XRRenderStateInit}} |newState| passed to this method will not be changed.

1. If |session|'s [=ended=] value is <code>true</code>, throw an {{InvalidStateError}} and abort these steps.

1. If |newState|'s {{XRRenderStateInit/baseLayer}}'s was created with an {{XRSession}} other than |session|, throw an {{InvalidStateError}} and abort these steps.

1. If |newState|'s {{XRRenderStateInit/inlineVerticalFieldOfView}} is set and |session| is an [=immersive session=], throw an {{InvalidStateError}} and abort these steps.

1. Let |activeState| be |session|'s [=active render state=].

1. If |session|'s [=pending render state=] is <code>null</code>, set it to a copy of |activeState|.

1. If |newState|'s {{XRRenderStateInit/depthNear}} value is set, set |session|'s [=pending render state=]'s {{XRRenderState/depthNear}} to |newState|'s {{XRRenderStateInit/depthNear}}.
