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.

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.

3KO

'3KO' is a 3D voxel/mesh visualization file format designed by NGRAIN Corporation of Canada (previously known as i3Dimensions). It was used with their interactive 3D training solutions for the aerospace, defense, and manufacturing sectors. It is generally a "one way" format from such software packages as 3ds Max and Maya into the NGRAIN software.

Going back in time to the 2003 era, Okino and NGRAIN collaborated on the development of the NGRAIN 3KO exporter within Okino software.
