Hi Neo,

We (geyser and Alloc) are positively impressed by your recent contributions to the "OBD" knowledge database. Wow.

What kind of activity (professional, Oni-related) has led you to such expertise? What tools do you use to analyse Oni?

OUP could use some expert OBD knowledge right now: we'd like to produce a fully functional release Soon(TM).

Would you consider private dialogue with us (mail, ICQ)? (about TXMP and recurrent data types)

Hi guys,

What's so much to be impressed, I just added some matrices here and there (mostly) ! :)

I've been digging through Oni binary files for some time now (I think it was the summer of 2002 when I opened a dat file in a hex editor out of curiosity and when I saw all this TXMP, PNTA, IDXA, M3GM etc. stuff I thought that maybe I can get something out of this binary format). While I'm not a game developer I have a bit of a passion for 3D stuff so I learned a bit of Open GL and a bit more of Direct 3D so I'm quite familiar with transforms, quaternions, textures etc.

As for used tools: much like anyone else I think. A hex editor, Excel for some things, SQL Server (database) for some others, Visual Studio (while it's file hex editor is quite dull it has a cool memory view in debug mode (you can set the number of displayed columns and the data type to display (integer/float, decimal/hexadecimal, 1/2/4 bytes). Obviously since this was in debug mode I had a program that loaded the DAT file into memory and where I could select a "file" (for various reasons I happened to call them "resources"). In addition I sometimes used a disasembler (home made, don't ask what it is) to stare at some things inside the executable :). Last but not least I have a "viewer" for a bunch of things from Oni (texures, 3D models, animations, environment). Good to test things like what I added to OBAN and OBOA file formats.

As for mail/messenger (MSN or Yahoo) I guess it's OK but I don't feel like posting my mail address in here, it's a public place... any ideas ?

Neo

OK, we won't ask you about your home-made disassembler ^^, but the viewer definitely sounds nice.

Viewers (and exporters/importers) for things other than TXMP is what OUP currently lacks.

Needless to say, we'd like to see those (is it C/C++?) and with any luck integrate them with OUP... ^^

As for contact, our coordinates are available (just click our sigs). My YIM alias is serguei_mechkov.

I only have a few more doubts about the TXMP format. Will experiment a little tomorrow night.

Your homemade tools remind me of someone from the previous Oni Central Forum... Have we met? ^^

geyser 02:53, 7 March 2007 (CET)

Nope, we had not met before. As for viewer I intend to make it available but not right now, I kept doing experiments with it for the last 2 weeks or so and the whole source looks like after a war. The current one is written in C#, I also have one that is written in C++ but it has not been updated in a while so it lacks/gets wrong some things. I'll add you to my YIM list and you can ask for more details there, I'm not familiar with this wiki stuff to write too much... :) Neo

I've tried to run your Onibrowser several times, but I've failed. The test system is a laptop with WinXp + SP2, .NET 2.0 and XNA 1.0. When I doubleclick on the exe the harddisk makes only some noise for some seconds. That's it. Nothing else happens. No error message, no window. Nothing. Any idea what's wrong?

Can you add some code to the vtuneapi.dll that draws the trigger volumes (volume color: red, opacity: 10%)?
