XRWebGLLayer.antialias
The read-only XRWebGLLayer
property
antialias
is a Boolean value which is true
if the rendering layer's frame buffer supports antialiasing. Otherwise, this
property's value is false
. The specific antialiasing technique used is left
to the user agent's discretion and cannot be specified by
the web site or web app.
Syntax
let antialiasingSupported = xrWebGLLayer.antialias;
Value
A Boolean value which is true
if the WebGL rendering layer's frame buffer
is configured to support antialiasing. 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 antialiasing mode only when
initially creating the XRWebGLLayer
, by specifying the antialias
property in the XRWebGLLayer()
constructor's layerInit
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 antialiasing on the WebGL
layer.
let glLayer = xrSession.renderState.baseLayer;
gl.bindFrameBuffer(gl.FRAMEBUFFER, glLayer.framebuffer);
/* .. */
if (!glLayer.antialias) {
/* compensate for lack of antialiasing */
}
