OGLE

OGLE: The OpenGLExtractor is a tool that lets you grab 3d data out of an OpenGL application and output it as models again.

What does that mean?

It means that someone with a 3d printer can get 3d statuettes of their Second Life character. They can send it off to be manufactured, if they like.
It means that you can snag any 3d model you like out of someone else’s game data, and insert it into your own 3d scene. So much for stealing textures…

The most intriguing results are of course from bringing the virtual stuff into meatspace (MMO companies have talked forever about making custom action figures of cherished characters, and now it looks like that business opportunity window might be closing…). There are so many applications there the head spins.

But I suspect the other use will be more likely: people using models to learn from and to repurpose.

So much for limiting your range of avatar poses, for example — now anyone with this software and 3d modeling software can build any scene they like. (They usually like pr0n). And what goofy game remixes will we get — freeware shooters where you shoot the Horde?

Very promising for machinima, though.

For an immediate idea of such possibilities check out this project brought to light by Fiezi where Theodore Watson is using this and Google Earth to create a machinima piece. Tres cool. As discussed on Raph Koster’s blog , your milage may very depending on the complexity of the game models your trying to extract and if the game supports OpenGL at all. But hey, sure is an awesome start…

Raph Koster has posted a tidbit on OGLE. I won’t regurgitate his info, but you can go read about it on his blog. I will say it’s pretty interesting and I’ll download and check it out tonight when I get home.

[...] Raph Koster’s blog has a link and some brief discussion of OGLE, a program that can extract 3D models from your favorite OpenGL game. For example, if you’re in love with your WoW character and you have the means, you can extract the model right from the game and come up with something like the above image. That’s not all though, Raph also mentions other uses like taking models from someone else’s game and sticking them into your own 3D space. Obviously there are some legal issues surrounding doing something like that, but it makes for some interesting opportunities. Game remixes, machinima with WoW and Doom characters fighting it out… lots of possibilities. You can download the program and try it yourself if you’ve got a 3D editing program handy. << Back to Main [...]

[...] This is awesome http://www.raphkoster.com/?p=282 Basically, there’s a project out there that allows you to capture 3d data from games that use OpenGL. You can then output models for use in other stuff, or even to be sent off to a 3d printer. Pretty cool stuff. Its still in early beta (hell, I’d call it alpha at this point) but looks like it could get really cool. __________________ Nippon Software beat you to it there, Harlie… —– Mario Kart DS Friend Code: 176153-450051 —– Zorpheus: What’s not to like about Hellsing?

Igor said on January 24th, 2006 at 11:16 am:

Ah, if I was still stubscribed, I’d want to capture my Star Wars Galaxies character with that (BTW, on that topic, Raph, do you have any involvement in the doings of SWG nowadays whatsoever? I’m not against the NGE like so many other people are, but I also think that the game is in a far less stable state now than it was at launch.).

The idea is definitely very clever. Might even motivate me to improve my 3D Animation skills so I can export and animate models from games. Very very promising and definitely makes such a field more user-friendly.

Raph said on January 24th, 2006 at 11:21 am:

I haven’t been involved with SWG since around the time Holocrons started dropping — so, literally, since a few months after launch. I started phasing out right as the game launched, and the last stuff I was really involved in were The Warren, cities, mounts, and (barely) vehicles.

Igor said on January 24th, 2006 at 11:40 am:

Have you followed or played at all? I was just always rather curious about the circumstances of your departure, considering that you had put so much into the game. Did you disapprove of the direction that the game was going before launch?

Raph said on January 24th, 2006 at 11:46 am:

The circumstances of my departure are that I was offered a promotion a few months before the game launched, and I took it, but said I had to stay on until launch. After launch, I transitioned off over the course of a few months.

I stay away from discussing the game on this blog.

Ivan-Assen said on January 24th, 2006 at 12:06 pm:

Not so fast.

To do this you need a game which a) uses OpenGL (although similar tools exist for DirectX and, what’s more important b) has very, very simple vertex shaders. For a game with reasonably complex skeletal animation, compressed vertices and maybe several vertex streams, and it quickly becomes an exercise in reverse-engineering. Not at all impossible, but a far cry from casual user stuff.

Raph said on January 24th, 2006 at 12:10 pm:

Yeah, on their webpage they actually have a list of games they have tried it with. The ones that use vertex shaders tend to come out in the bind pose, based on what I read there…

Tess said on January 24th, 2006 at 5:38 pm:

That sounds like what I’d expect, yeah. Though, you could presumably repose the model using another piece of software, prior to printing, if that was your goal. (Still a pain in the neck if you’re just the average player.)

Raph said on January 25th, 2006 at 9:04 am:

Slashdotted!

Raph said on January 25th, 2006 at 10:19 am:

Darn it, Zonk, you knocked “Moore’s Wall” off the Top 10.

Michael Frumin said on January 25th, 2006 at 10:25 am:

hey all, author of OGLE here. I discovered that some games don’t actually require Vertex Programs for positioning. Using GLIntercept to disable Vertex Programs actually allows for a much better capture (i.e. positioning as you see in the game), as I have just added to the FAQ:

http://ogle.eyebeamresearch.org/readme#faq

Thanks for all the interesting feedback!

All very interesting… or you can always buy cardboard cutouts of your characters via eBay.

csven said on January 26th, 2006 at 7:17 am:

In case anyone is interested, I blogged about the implications of this last year when I used HijackGL to grab data and then converted it over to “solid” geometry typically used for manufacturing. In effect, I was showing how 3D data could be not only ripped from a stream, but how it could be turned into manufacturable CAD data intended not just for rp systems, but mass production… with the associated repercussions on a wide range of topics.

The details of the conversion are at the end of a rather long post that’s actually more about marketing than engineering or design. You can read that here: http://blog.rebang.com/?p=186

If the convergence issue is of interest (i.e. you slugged through the whole post), you might want to read something more recent (and even longer, sorry): http://blog.rebang.com/?p=577
