A projection metadata system and method are provided for providing projection metadata to a rendering system for use in rendering a panoramic scene. A rendering system and method are provided for rendering the panoramic scene using the projection metadata. The projection metadata may comprise machine readable data which may directly provide the coordinate mapping to be used in by the rendering system to render the panoramic scene. For example, an executable script may be provided which, when executed, carries out the coordinate mapping. Compared to known ways of signalling a rendering system which projection to use, which may conventionally involve selecting a projection from a number of predefined projections and signalling the selection, the use of projection metadata may provide a high degree of flexibility, as different projections may be defined for, e.g., different spatial and/or temporal parts of the panoramic scene, different rendering techniques, etc.

Coordinate mapping for rendering panoramic scene

Some embodiments involve obtaining access to a number of omnidirectional images each representing a different viewpoint relative to a scene, and to metadata indicating a physical relation between the respective viewpoint and a physical object in the scene. Viewer data may be obtained that is indicative of a current physical relation between a viewpoint of the user and a same type of physical object in a current viewing environment of the user. An omnidirectional image may then be selected for display by comparing the viewer data to the metadata of the omnidirectional images. In other embodiments, an omnidirectional image may be selected, e.g., from omnidirectional images or by being the only available image, and the user may be instructed to assume a viewpoint in which the physical relation to the physical object in the user's current viewing environment corresponds to the physical relation as indicated by the selected image's metadata.
