XRRenderStateInit dictionary is a writeable version of the XRRenderState interface, and is used when calling an XRSession 's updateRenderState() method to apply changes to the render state prior to rendering the next frame.

All distances are specified as floating-point values in meters ; you can specify a value of 50 centimeters using a value of 0.5, for example.


baseLayer 可选
An XRWebGLLayer object from which the WebXR compositor will obtain imagery. This is null 在默认情况下。
depthFar 可选
A floating-point value specifying the distance in meters from the viewer to the far clip plane , which is a plane parallel to the display surface beyond which no further rendering will occur. All rendering will take place between the distances specified by depthNear and depthFar . This is 1000 meters (1 kilometer) by default.
depthNear 可选
A floating-point value indicating the distance in meters from the viewer to a plane parallel to the display surface to be the near clip plane . No part of the scene on the viewer's side of this plane will be rendered. This is 0.1 meters (10 centimeters) by default.
inlineVerticalFieldOfView 可选
A floating-point value indicating the default field of view, in radians, to be used when computing the projection matrix for an inline XRSession . The projection matrix calculation also takes into account the output canvas's aspect ratio. This property 不必 be specified for immersive sessions, so the value is null by default for immersive sessions. The default value is otherwise π * 0.5 (half of the value of pi).

Usage notes

Any properties not specified in the XRRenderStateInit compliant object passed into updateRenderState() are left at their current values.
