OpenXR cookbook

Below are some common OpenXR how-to questions that we are often asked as developers dive in on building engines that target the OpenXR API.

How can my app recenter its reference space?

To recenter a reference space such as LOCAL space or STAGE space:

1. Call xrLocateSpace to find the current location of the VIEW reference space within the reference space you are recentering.
2. Call xrCreateReferenceSpace again for the reference space you are recentering, adding the current VIEW pose to the poseInReferenceSpace field on your XrReferenceSpaceCreateInfo struct.
3. Call xrDestroyReferenceSpace on the old reference space handle and start using your new recentered reference space in its place.

Be sure to stash away the XrReferenceSpaceCreateInfo struct you use in step 2, so that the next time you need to recenter, you can add the then-current VIEW pose to the struct's accumulated poseInReferenceSpace field.
