Methods and apparatus for systems using a scene codec are described, where systems are either providers or consumers of multi-way, just-in-time, only-as-needed scene data including subscenes and subscene increments. An example system using a scene codec includes a plenoptic scene database containing one or more digital models of scenes, where representations and organization of representations are distributable across multiple systems such that collectively the multiplicity of systems can represent scenes of almost unlimited detail. The system may further include highly efficient means for the processing of these representation and organizations of representation providing the just-in-time, only-as-needed subscenes and scene increments necessary for ensuring a maximally continuous user experience enabled by a minimal amount of newly provided scene information, where the highly efficient means include a spatial processing unit.

Codec for processing scenes of almost unlimited detail

A stored volumetric scene model of a real scene is generated from data defining digital images of a light field in a real scene containing different types of media. The digital images have been formed by a camera from opposingly directed poses and each digital image contains image data elements defined by stored data representing light field flux received by light sensing detectors in the camera. The digital images are processed by a scene reconstruction engine to form a digital volumetric scene model representing the real scene. The volumetric scene model (i) contains volumetric data elements defined by stored data representing one or more media characteristics and (ii) contains solid angle data elements defined by stored data representing the flux of the light field. Adjacent volumetric data elements form corridors, at least one of the volumetric data elements in at least one corridor represents media that is partially light transmissive. The constructed digital volumetric scene model data is stored in a digital data memory for subsequent uses and applications.

Systems and methods deform the surface of the material with a probe, such as a mechanical device or a gas/liquid jet, while optically recording in detail the three-dimensional (3D) topography of the resulting surface deformation. The probe effectively applies a forcing function to the material, the attributes of which are known by performing calibrations prior to use or by direct measurement while it is applied. The topography is effectively the system output that is measured as indicative of the underlying mechanical properties of the material. In one application, systems and methods that apply a pressure in-vivo to human tissue and analyze a three-dimensional topography of the resulting surface deformation to identify localized inhomogeneities and anomalies in the human tissue.

In accordance with one aspect, the present invention provides a real-time 3D visualization system. The system includes means for conveying electromagnetic energy emanating from one or more 3D surfaces including a scene and means for sensing spatial phase characteristics of the electromagnetic energy as the configuration of the 3D surfaces relative to the system changes. The system includes means for creating a 3D scene model utilizing the spatial phase characteristics sensed in a plurality of configurations and means for displaying the 3D scene model in real-time. The means for displaying includes means for synthesizing depth cues.
