XRWebGLLayerInit.alpha
Secure context
This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
The alpha
property is a Boolean
value which, if present and set to true
in the
XRWebGLLayerInit
dictionary passed into the
XRWebGLLayer()
constructor, specifies that
the new layer's color buffer is to include an alpha
channel. Otherwise, the color buffer won't have an alpha channel. The
default is true
.
Syntax
let layerInit = {
alpha: boolValue
};
let glLayer = new XRWebGLLayer(xrSession, gl, layerInit);
let glLayer = new XRWebGLLayer(xrSession, gl, { alpha: boolValue });
Value
A Boolean which can be set to true
to request that the new WebGL layer for
rendering the WebXR scene is to have an alpha channel.
Example
In this example, a new XRWebGLLayer
is created for a WebXR session,
xrSession
, without an alpha channel.
xrSession.updateRenderState({
baseLayer: new XRWebGLLayer(xrSession, gl, {
alpha: false
});
});
