How to convert PRC (Adobe 3D PDF) to OpenFlight (.flt)?

PolyTrans|CAD+DCC performs mathematically precise CAD, DCC/Animation, GIS and BIM 3D file conversions into all key downstream 3D packages and file formats. Okino software is used and trusted throughout the world by many tens of thousands of 3D professionals in mission & production critical environments, backed by respectable personal support directly from our core development team.

PRC

PRC (Product Representation Compact) is probably one of the least known of 3D CAD file formats yet it forms the underpinning for Adobe Acrobat 3D PDF files. It may be considered the “silent younger brother of the more well known U3D file format”. It has a fairly long but little unknown history.

PRC is primarily used as a 3D file format to embed 3D data within a PDF file. It was originally developed by the TTF Group of France whom were purchased by Adobe in 2006. In 2014 PRC became an ISO published standard.

Okino's PRC geometry import converter reads in native PRC 3D CAD files. It will also extract PRC and U3D files from within any chosen page of an Adobe 3D PDF file. It is an intelligent and well implemented importer for all forms of complex source PRC CAD file data, including the import and processing of 3D mesh and BREP (solids) geometry, assembly hierarchy (incl. intelligent “proto node” handling), materials (with adherence to the PRC father/son inheritance rules), 2D bitmapped texture maps and meta data.

OpenFlight

OpenFlight is an industry standard realtime 3D scene description format developed, owned and maintained by Presagis, Inc. OpenFlight is the most widely used file format for visual simulation databases and is supported by dozens of vendors of realtime 3D tools. Military visual simulation includes battle simulation, fighter jet flight simulation, tank simulation. Visual simulation also includes geospecific terrain for accurate realtime fly through of regions of the planet.

In visual simulation, OpenFlight is the defacto standard format. OpenFlight is also prevalent in the PC animation and modeling communities for optimizing and tagging 3D data for realtime playback. As application examples, in the visual simulation industry OpenFlight is the format for entire worlds. In the entertainment industry it is widely used for level building in realtime games and in the AES or urban simulation industries it is used to organize and optimize scenes for realtime walkthroughs.
