XRWebGLLayer: antialias property
The read-only XRWebGLLayer
property antialias
is a Boolean value which is true
if the rendering layer's frame buffer supports anti-aliasing. Otherwise, this property's value is false
. The specific anti-aliasing technique used is left to the user agent's discretion and cannot be specified by the website or web app.
Syntax
Value
A Boolean value which is true
if the WebGL rendering layer's frame buffer is configured to support anti-aliasing. Otherwise, this property is false
.
When the WebXR compositor is enabled, this value corresponds to the value of the antialias
property on the object returned by the WebGL context's getContentAttributes()
method.
Usage notes
Since this is a read-only property, you can set the anti-aliasing mode only when initially creating the XRWebGLLayer
, by specifying the antialias
property in the XRWebGLLayer()
constructor's options
configuration object.
Examples
This snippet checks the value of antialias
to see if it should perform additional work to attempt to compensate for the lack of anti-aliasing on the WebGL layer.
let glLayer = xrSession.renderState.baseLayer;
gl.bindFrameBuffer(gl.FRAMEBUFFER, glLayer.framebuffer);
if (!glLayer.antialias) {
}
