How to convert PLY (Stanford .ply) 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.

     

PLY

PLY can generally be considered a simple, 1990s-era, university research oriented polygonal (mesh) 3D file format designed to store data from 3D scanners. It was developed by Greg Turk and others in the Stanford graphics. Its design was inspired by the Wavefront .obj format.

PLY was meant to be a simple, easily parsable file format and hence only conveys basic geometry information for a single object definition with polygon vertices, vertex colors vertex normals and UV texture coordinates. No materials nor hierarchy, lights or cameras are supported.

     

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.
