Just wanted to share some nice screenshots that has been taken by my API users.

that is mindblowin dude!! good job.
wow,
looks great! Page 3 impressed me the most. Is it a 3d scene or just a texture?
whats the framerate? does it run in realtime? What hardware does gizmo3d run on?
Thanx !
All images are true 3D databases that can be viewd from ground postition to flight position.
Framerates are 30+ or higher on Typical current generation of nVidia and ATI HW.
Gizmo3D runs on Win32, Irix, Linux etc. using standard OpenGL or DirectX HW.
You can find more info on http://www.tooltech-software.com
You work for saab?
Yes.
Gizmo3D is beeing merged into Saab Training Systems. Its to big for me now as a single developer.
Nice Job
I should really give A LOT OF CREDIT to the customers that made the databases and applications in the pictures.
Do your customers have to optimize display for such huge terrains like the ones shown in your pictures or does your library handle it all?
The scene graph has discrete and continious LOD features, Billboards, impostors etc. that fixes that. Customer just use tools like MultiGen/Terrapage or even 3D Studio and creates the DB. The DB is then entered into Gizmo3D. You can also use paging to just load a part of the DB. E.g. STS uses maps that are 50-100 GBytes large.
Cool screenshots Anders, its nice to see Gizmo3D coming along since the merger with Saab.
In the spirit of free advertising, if you want so see more of what scene graphs can do have a look at
http://openscenegraph.sf.net/screenshots
and from the 3DStudio exportor OSGexp:
http://osgexp.vr-c.dk/?Home/Screenshots
Many of the models in the screenshots are loaded from similar databases formats that Gizmo3D can read too (OpenFlight/TerraPage/3DStudio), so I’d expect Gizmo3D could just a nice job at rendering them too.
Of course what makes a scene graph, is not just the ability to honour the quality of the databases, but to ensure a solid 60Hz framerate. Not possible on all models, but with modern hardware its amazing how much you can quality and magnitude of mdel you can squeeze in and still comfortably hit 60Hz

That’s really massive. Who does the memory management and what system they run it on?
The memory management is handled by the Gizmo3D memory management (Gizmo3D has a base abstraction layer (gzBase) for the plattform that manages all memory, threads , mutexes etc.)
STS uses it for their Combat Training Centers (CTC) software in the 2D/3D map presentation. Typical PC HW. Have a look at http://www.saab.se/training/
Woah Robert, that was a bit tight don’t you think?
Linking to scenegraph screenshots that look 1000% better than tooltechs…unforgiveable.
It’s all in the art assets, don’t you know.

I agree 100%, but surely you missed my statement to this affect i.e that Gizmo3D could read many of the same models that the OSG screenshots were based upon
Personally I think scene graphs are really useful technologies, and there are some great close and open source ones out there. The linked to screenshots give a bit of taste, but once you start viewing multi-gigabyte datasets at a solid 60Hz then you really know their value.
