Converting OpenFlight Terrain and Models to MVRsimulation Formats

CONVERTING OPENFLIGHT TERRAIN AND MODELS TO MVRSIMULATION FORMATS

You can convert OpenFlight format terrain and models to the MVRsimulation's runtime formats by using MVRsimulation's free utilities that are distributed with VRSG:

  • terrex-oflt2Mds.exe – converts an OpenFlight format terrain database produced with Terra Vista or Synthetic Environment Core (SE Core) to MVRsimulation's round-earth VRSG terrain tile format (MDS).
  • oflt2Hpx.exe – converts an OpenFlight format model to MVRsimulation's HPX model format.

These tools provide the means of both reusing legacy OpenFlight terrain and models in VRSG and the ability to create new terrain and models in OpenFlight format with tools such as Presagis Creator or Terra Vista.

MVRsimulation also provides a plugin for Presagis Creator that converts an OpenFlight format dynamic model to a model in MVRsimulation's HPX model format directly inside Creator. This plugin uses the OpenFlight API as part of the OpenFlight Developers Program, which provides access to OpenFlight Read/Write/Extension APIs for creating OpenFlight runtimes, converters, database extensions, and database optimization tools.

To use the model conversion plugin, first move the hpxPlugin.dll (which is installed with any MVRsimulation product) from the \MVRsimulation\Common\Util directory to the Creator\Plugins directory, and then start Creator. The \MVRsimulation\Common\Util directory also includes command-line converters for OpenFlight to MVRsimulation terrain and model formats.

Currently, external references are not supported in the OpenFlight API for Plug-ins. However, the command-line versions of MVRsimulation's OpenFlight converters, which are distributed with any MVRsimulation software installation, do support external references. See the MVRsimulation VRSG User's Guide for information about using the OpenFlight-to-MVRsimulation format converters.

Note that attempting to convert a model that is in MVRsimulation's proprietary model format to another format is strictly prohibited by MVRsimulation's software license agreement.
