安全上下文
此特征只可用于安全上下文 (HTTPS)，在某些或所有支持浏览器 .

The Boolean antialias property, if present and set to true 在 XRWebGLLayerInit object provided as the XRWebGLLayer() constructor's layerInit parameter, requests that the new WebGL rendering layer support anti-aliasing. If this property is missing or is false , anti-aliasing is not desired.

There is no way to request a specific anti-aliasing format or level; this decision is left up to the 用户代理 .

句法

let layerInit = {
  antialias: boolValue
};
let glLayer = new XRWebGLLayer(xrSession, gl, layerInit);
let glLayer = new XRWebGLLayer(xrSession, gl, { antialias: boolValue });

值

A Boolean value which can be set to true to request anti-aliasing support in the new WebGL rendering layer. If false , anti-aliasing is not desired.

用法注意事项

The state of anti-aliasing for the context after being created can be read from the XRWebGLLayer property antialias .

范例

In this example, before creating a new XRWebGLLayer to use for rendering, the value of a user preference from a configuration interface is obtained using a function called getPreferenceValue() to determine whether the user has enabled or disabled anti-aliasing support; this is passed into the constructor.

let options = {
  antialias: getPreferenceValue("antialiasing")
};
let glLayer = new XRWebGLLayer(xrSession, gl, options);
if (glLayer) {
  xrSession.updateRenderState({ baseLayer: glLayer });
}

Offering the user features such as the ability to enable or disable things like anti-aliasing can provide them with optiions to try when your app isn't performing as well as they'd like. Disabling anti-aliasing may improve performance to some extent.
