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 ?
