This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the
兼容性表格
at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
getPose()
方法在
VRDisplay
interface returns a
VRPose
object defining the future predicted pose of the
VRDisplay
as it will be when the current frame is actually presented.
This method is deprecated — instead, you should use
VRDisplay.getFrameData()
, which also provides a
VRPose
对象。
var myPose = vrDisplayInstance.getPose();
None.
A
VRPose
对象。
Once we have a reference to a
VRDisplay
object, we can retrieve the
VRPose
representing the current pose of the display.
if(navigator.getVRDisplays) {
console.log('WebVR 1.1 supported');
// Then get the displays attached to the computer
navigator.getVRDisplays().then(function(displays) {
// If a display is available, use it to present the scene
if(displays.length > 0) {
vrDisplay = displays[0];
console.log('Display found');
// Return the current VRPose object for the display
var pose = vrDisplay.getPose();
...
}
});
}
It is however recommended that you use the non-deprecated
pose
特性为
VRFrameData
object (retrieved via
VRDisplay.getFrameData()
) to retrieve the current pose for each frame before it is submitted to the display to be presented. This happens on each iteration of the rendering loop for your app, so you can be sure the pose data is current.
