当使用 XRWebGLLayer() constructor to create a new WebGL rendering layer for WebXR, providing as the layerInit parameter an object whose stencil 特性为 false requests that the new layer be created without a stencil buffer.

stencil buffer is an optional buffer which, just like the depth buffer, contains one entry for every pixel in the frame buffer. Also just like the depth buffer, the value of an enter in the stencil buffer directly affects how (or if) the corresponding pixel is drawn during rendering. You can store values into each entry in the stencil bufer, then specify an operation that determines which stencil buffer values correspond to pixels which should be drawn to the screen during each frame.

句法

let layerInit = {
  stencil: false
};
let glLayer = new XRWebGLLayer(xrSession, gl, layerInit);
let glLayer = new XRWebGLLayer(xrSession, gl, { stencil: false });

值

A Boolean which can be set to false to specify that the new WebGL layer should not include a stencil buffer. The default value is true .

范例

In this example, a new XRWebGLLayer is created for a WebXR session, xrSession , without a stencil buffer.

xrSession.updateRenderState({
  baseLayer: new XRWebGLLayer(xrSession, gl, {
     stencil: false
  });
});
