XRView: recommendedViewportScale property
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The read-only recommendedViewportScale
property of the XRView
interface is the recommended viewport scale value that you can use for XRView.requestViewportScale()
if the user agent has such a recommendation; null
otherwise.
Value
A number greater than 0.0 and less than or equal to 1.0; or null
if the user agent does not provide a recommended scale.
Examples
Dynamic viewport scaling
Dynamic viewport scaling allows applications to only use a subset of the available framebuffer
. The feature may not be available on all systems since it depends on driver support, so you might want to ensure that XRView.requestViewportScale
exists before calling it.
js
for (const view of pose.views) {
if (view.requestViewportScale) {
view.requestViewportScale(view.recommendedViewportScale);
}
const viewport = glLayer.getViewport(view);
}
