Re: [osg-users] DWB
No problem. And thanks for you reply. We are considering to use CarbonGraphics' software to do the DWB -> OpenFlight conversion. Thanks anyway.

Re: [osg-users] DWB
Joakim, I realize this is quite delayed, please accept my apologies. Unfortunately, for reasons which I cannot disclose, I'm prohibited by my employer from releasing any of the DWB/Coryphaeus Software documentation or other such materials. If you run into a snag, I'll certainly _attempt_ to help you out - just pose a question to the list or email me privately at hamm at simauthor[dot com]. I'd be interested in hearing about what you end up doing with the DWB assets that you're dealing with (using GEO, OpenFlight, or some other such format/toolchain).

Re: [osg-users] DWB
Thank you for your answers! I knew that this place was the correct place to ask this question :) A client wants to use their old databases (dwb) with our osg-based apps. When I googled the dwb format, I found out that there exists a dwb->flt converter (http://www.agocg.ac.uk/reports/virtual/36/appendix.htm). But the link on this page is broken. It refers to the non-existing www.coryphaeus.com site. "dwb2oflt - converts DWB files to OpenFlight format." It seems that this converter was free for download. If anyone have this converter please let me know! Carbon graphics' software sounds interesting, I will investigate in this. A dwb plugin for OSG could of course be another solution (but a very time-demanding one). In this case, format specs. will be of high interest for us.

Wow! Sounds like you've done a lot with DWB since I left SimAuthor a year ago. Did you ever find any documentation for (I think they were called) link nodes? -- the records that specified input variables and the functions/formulas that tied them to transform nodes/strings/etc within the model. That was missing in the most current version of the spec I had while at I was at SimAuthor. Really frustrating as that appeared to be the single feature of DWB that made it a valuable file format. If you're asking for permission to distribute this stuff for a DWB plugin project, you might also investigate whether or not SimAuthor is at liberty to distribute the RTM code. Lacking a complete and current spec, that old K&R C code is the best description of the DWB format around.

Re: [osg-users] DWB
Joakim, Just a follow up to what Paul stated, Carbon Graphics GEO model database specification is far superior to DWB, for all the reasons Paul stated. However...if you're like he was (and I am now) forced to stick with DWB for the time being, I have some materials in my possession that may be of use to you. What sort of information are you looking for? The model format specification (Binary or ASCII)? General questions? If you need some docs, I have an almost complete collection of the DWB SDK documentation that I pulled off of one our old SGI machines. I also wrote a very simple python script that runs over a DWB database and dumps some information about it (I use it to "diff" two DWB models as the DWB modelling package never seems to be consistent about how it writes out the model at any given time), as well as some old SDK example code for parsing a DWB database from Coryphaeus Software (now defunct). All this aside, I'll need to get permission from SimAuthor to release them. The documents say that the format is open-source, but I need to "C-M-A" and ask for permission first. Are you planning to write a DWB plugin for OSG? If so, do you plan to release it back to the community? Maybe we could make it a joint effort? Let me know what you need, and I'll see what I can get for you.
