That's neat...a lot more folks coming out of the closet that are using OSG-based IGs using CIGI...;^).
Actually CIGI is quite prolific in the IG industry which is nice for anyone who has a host that has to interface with different IGs or wants to upgrade to a different IG that supports CIGI. You don't have to rewrite the communication protocol to switch IGs... I think VT Mak is another high profile IG vendor that uses OSG technology under the hood that may support CIGI. The last time I glanced at Boeing's MPV code, they had upgraded it to support OSG 2.8.2. They've jettisoned most of the SDL dependencies and are now using the osgViewer paradigm along with other, more modern OSG concepts. The blackboard paradigm still exists with some enhancements. I don't consider myself a prognosticator but I predict that you will see more IGs emerge, based on OSG and other open source tools. They will eventually replace IGs that rely on proprietary scenegraphs and databases because of reduced cost. In the early days, IG vendors relied on proprietary hardware to introduce their discriminators from the competition. With the advent of programmable GPUs found on COTS cards such as NVIDIA and ATI, most of those proprietary hardware discriminators have evaporated and many have had to retreat to proprietary scenegraphs, tools, and databases to maintain their business edge. I think you will see a similar revolution in the software realm as open source tools like OSG make inroads into the current IG market. Proprietary software used by most IG vendors today (such as scenegraphs and databases) could suffer the same fate as proprietary IG hardware did back in the 90's... -Shayne -----Original Message----- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Lionel Lagarde Sent: Wednesday, May 29, 2013 8:06 AM To: OpenSceneGraph Users Subject: Re: [osg-users] Any recent work on CIGI interfaces to OSG? Hi, I work on an image generator based on OpenSceneGraph and driven by CIGI commands. Web site of the company: http://www.oktal-se.fr Section SE-FAST-IG. At first MPV was a source of inspiration. This is no longer the case now. It's been a few years since I look at MPV base code.

I have read the conversations about doing this from several years ago, but have not found any recent discussion or located any available code drops. I have downloaded the MPV example from CIGI at sourceforge, which is based on OSG, and that is quite helpful, but I wanted to introduce myself here and see if anyone can catch me up on any other existing work in this direction, or give me advice about where to start. Much of the CIGI interface is dedicated to higher order simulation functions (ie celestial bodies, ocean conditions, aircraft controls) which are probably too specific to implement at the OSG layer, but I'd like to make at least a virtual wrapper in OSG which could be inherited by FlightGear and other OSG based projects, each of which could determine on its own which functions to support, and how to support them. Any pointers would be welcome. I am applying for funding for this project in one week, so the more information I can gather before then the better. Thanks for all your efforts!
