XRTransientInputHitTestResult

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The XRTransientInputHitTestResult interface of the WebXR Device API contains an array of results of a hit test for transient input, grouped by input source.

You can get an array of XRHitTestResult objects for a frame by calling XRFrame.getHitTestResultsForTransientInput().

Instance properties

XRTransientInputHitTestResult.inputSource Read only

Represents the XRInputSource that was used to compute the results array.

XRTransientInputHitTestResult.results Read only

Represents an array of XRHitTestResult objects containing the hit test results for the input source, ordered by the distance along the ray used to perform the hit test, with the closest result at position 0.

Instance methods

None.

Examples

Accessing transient input hit test results

Two arrays are used to access transient input hit test results. First, you get an array of XRTransientInputHitTestResult objects by calling XRFrame.getHitTestResultsForTransientInput(). Second, to get to the actual XRHitTestResult objects for an input source, you dereference the results property on one of the XRTransientInputHitTestResult objects.

js
// frame loop
function onXRFrame(time, xrFrame) {
  let hitTestResults = xrFrame.getHitTestResultsForTransientInput(
    transientHitTestSource,
  );

  hitTestResults.forEach((resultsPerInputSource) => {
    resultsPerInputSource.results.forEach((hitTest) => {
      // do something with the hit test
      hitTest.getPose(referenceSpace);
    });
  });
}

Filtering input sources

The inputSource property allows you to filter hit test results by input source.

js
// frame loop
function onXRFrame(time, xrFrame) {
  let hitTestResults = xrFrame.getHitTestResultsForTransientInput(
    transientHitTestSource,
  );

  hitTestResults.forEach((resultsPerInputSource) => {
    if (resultsPerInputSource.inputSource === myPreferredInputSource) {
      // act on hit test results from the preferred input source
    }
  });
}
