An apparatus and method provide for occlusion detection. An example apparatus includes means for: receiving first data comprising a reference viewpoint of a real-world space; receiving second data comprising a position of a target object in the real-world space; transforming, based on the first and second data, at least one of the reference viewpoint and the target object position into a common virtual reference space; generating one or more rays which extend between the reference viewpoint and a respective spatial point associated with the position of the target object in the common virtual reference space; and determining the digital model representing the real-world space and including one or more real-world features, an occlusion status between the reference viewpoint and the target object. The occlusion status is based on an intersection of the one or more real-world features and the one or more generated rays.

Occlusion detection

Methods, devices, and computer program products are provided for rendering selective light field representations for new images of a scene by extending the plenoptic function range to include a null radiance term such that rays characterized by the extended plenoptic function L(x, y, z, &#x3b8;, &#x3d5;) may return the null radiance term to denote that an instantiator should use a non-light field model or rendering engine to generate an appropriate replacement for that ray. Multiple viewers can be grouped based upon viewer behavior and/or virtual viewpoint within the scene. Round-trip time for sending/receiving communications between a server or processor and one or more user devices, as well as viewer behavior, can be used to predict for which light rays the corresponding light field data needs to be transmitted based on a probability that the light ray will be called upon during near-future rendering for a user.
