VRFrameData

{{APIRef("WebVR API")}} {{Deprecated_Header}} {{Non-standard_Header}} 

The VRFrameData interface of the WebVR API represents all the information needed to render a single frame of a VR scene; constructed by {{domxref("VRDisplay.getFrameData()")}} .

[!NOTE] This interface was part of the old WebVR API. It has been superseded by the WebXR Device API.

Constructor

• {{domxref("VRFrameData.VRFrameData", "VRFrameData()")}}  {{Deprecated_Inline}}  {{Non-standard_Inline}} 
  • : Creates a VRFrameData object instance.

Instance properties

• {{domxref("VRFrameData.leftProjectionMatrix")}}  {{Deprecated_Inline}}  {{ReadOnlyInline}}  {{Non-standard_Inline}} 
  • : A {{jsxref("Float32Array")}}  representing a 4x4 matrix that describes the projection to be used for the left eye’s rendering.
• {{domxref("VRFrameData.leftViewMatrix")}}  {{Deprecated_Inline}}  {{ReadOnlyInline}}  {{Non-standard_Inline}} 
  • : A {{jsxref("Float32Array")}}  representing a 4x4 matrix that describes the view transform to be used for the left eye’s rendering.
• {{domxref("VRFrameData.pose")}}  {{Deprecated_Inline}}  {{ReadOnlyInline}}  {{Non-standard_Inline}} 
  • : The {{domxref("VRPose")}}  of the {{domxref("VRDisplay")}}  at the current {{domxref("VRFrameData.timestamp")}} .
• {{domxref("VRFrameData.rightProjectionMatrix")}}  {{Deprecated_Inline}}  {{ReadOnlyInline}}  {{Non-standard_Inline}} 
  • : A {{jsxref("Float32Array")}}  representing a 4x4 matrix that describes the projection to be used for the right eye’s rendering.
• {{domxref("VRFrameData.rightViewMatrix")}}  {{Deprecated_Inline}}  {{ReadOnlyInline}}  {{Non-standard_Inline}} 
  • : A {{jsxref("Float32Array")}}  representing a 4x4 matrix that describes the view transform to be used for the right eye’s rendering.
• {{domxref("VRFrameData.timestamp")}}  {{Deprecated_Inline}}  {{ReadOnlyInline}}  {{Non-standard_Inline}} 
  • : A constantly increasing timestamp value representing the time a frame update occurred.

Examples

See VRDisplay.getFrameData() for example code.

Specifications

This interface was part of the old WebVR API that has been superseded by the WebXR Device API.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.
