XRRenderStateInit dictionary is a writeable version of the
XRRenderState interface, and is used when calling an
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.
XRWebGLLayerobject from which the WebXR compositor will obtain imagery. This is
- 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
depthFar. This is 1000 meters (1 kilometer) by default.
- 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.
- A floating-point value indicating the default field of view, in radians, to be used when computing the projection matrix for an
XRSession. The projection matrix calculation also takes into account the output canvas's aspect ratio. This property must not be specified for immersive sessions, so the value is
nullby default for immersive sessions. The default value is otherwise π * 0.5 (half of the value of pi).
Any properties not specified in the
XRRenderStateInit compliant object passed into
updateRenderState() are left at their current values.
