What's New

Significant changes in version 1.02 include:

• Added a new profile PosedCollection and elements for Mesh and NavigationalConnectivity to support a Streetview-style use case (collections of posed panorama images and scene geometry).

Significant changes in version 1.01 include:

• Added a new Profile element for describing the intended use case of the container image with the XDM metadata. For example, the XDM metadata for a depth photo is structurally different from that for a virtual reality photo. This element allows an image reader to quickly identify the media type without having to parse all the metadata, and identify the intended usage of each camera listed in the CameraIndices list.
• Added an EquirectModel to support rendering for equirectangular panoramas.
• Added a FisheyeModel to support rendering for equirectangular panoramas.
• Added Audio fields (data and media type) to Camera that represent an audio track. An example use case is recording audio with an image, such as with virtual reality photography.
• Deprecated the ContainerSignature field in Device, originally intended as a required field for detecting whether or not a container image was edited by a non-XDM-aware app. Computation of the signature is non-trivial, and therefore not likely to be universally implemented.
• Added a LensDistortionType field to PerspectiveModel, to support other distortion models such as that for a fisheye lens.
• Added a Timestamp field to DevicePose. This simplifies the access to global capture time information without having to search for a particular Camera.
