VRPose: orientation property
Deprecated
Avoid using this feature in new projects. Development of the WebVR API halted in favor of WebXR. This feature may be a candidate for removal from web standards or browsers.
Consider using the following features instead: WebXR.
Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.
The orientation read-only property of the VRPose interface returns the orientation of the sensor at the current timestamp, as a quaternion value.
Note: This property was part of the old WebVR API. It has been superseded by the WebXR Device API.
The value is a Float32Array, made up of the following values:
- pitch — rotation around the X axis.
- yaw — rotation around the Y axis.
- roll — rotation around the Z axis.
- w — the fourth dimension (usually 1).
The orientation yaw (rotation around the y axis) is relative to the initial yaw of the sensor when it was first read or the yaw of the sensor at the point that VRDisplay.resetPose() was last called.
Value
A Float32Array, or null if the VR sensor is not able to provide orientation data.
Examples
See VRDisplay.getFrameData() for example code.
Note:
An orientation of { x: 0, y: 0, z: 0, w: 1 } is considered to be "forward".
Specifications
This property was part of the old WebVR API that has been superseded by the WebXR Device API. It is no longer on track to becoming a standard.
Until all browsers have implemented the new WebXR APIs, it is recommended to rely on frameworks, like A-Frame, Babylon.js, or Three.js, or a polyfill, to develop WebXR applications that will work across all browsers. Read Meta's Porting from WebVR to WebXR guide for more information.
