1. An apparatus for implementation of a system for panoptic visualization of a three-dimensional (3D) representation of a complex system, the apparatus comprising a processor and a memory storing executable instructions that, in response to execution by the processor, cause the apparatus to implement at least: a visualization engine configured to receive a digital 3D model of a complex system and from the digital 3D model, produce a plurality of electronic document components including two-dimensional (2D) images depicting elements of the complex system; and a data extractor coupled to the visualization engine and configured to generate 2D derivatives of the 3D model, including for each of one or more document components, the data extractor being configured to: receive the document component including a 2D image depicting an element of the complex system, and extract from the 3D model, information identifying a spatial, design or functional relationship between the respective element and one or more other, different elements of the complex system depicted by the respective 2D image or another 2D image of the 2D images depicting elements of the complex system; and provide the extracted information as structured information in metadata according to some metadata schema and associated with the document component, wherein the data extractor is configured to communicate the 2D derivatives for inclusion in a panoptic visualization document collection, the 2D derivatives including the document components and associated metadata.
