Re: FastLSM soft body physics (source code available)

My misunderstanding -- sorry! At any rate, the 2D demo is not the one that is intended to impress people; the 3D demo is a bit better (it has the O(1) implemented), but I still haven't put a ton of time into it (it's not widely tested and all you can do is spawn objects). As for the claim of real-ti...

Re: FastLSM soft body physics (source code available)

But there are existing ways to do soft-bodies at real-time rates; complete with tearing, that are unencumbered by patents. This method is significantly faster. You should really implement the O( w ) thing at least. If you want to sell this, you need to make it clearly better than anything else on t...

Re: Position Based Dynamics: Patent

In response to 1), it's still a provisional patent so the claims haven't been put in yet. So I'll dodge that issue for now. As for 2), I don't think I'm being greedy, as I simply wouldn't have worked on the invention if I hadn't had the prospect of remuneration. Thus I think doing the work and tryin...

Re: Position Based Dynamics: Patent

I think part of the problem we have in communicating on this issue is the fact you want to argue generalities when it is the specifics that are at fault. I think you're right. You've quite rightly pointed out I'm very ignorant about a lot of the issues of patents, and I don't feel that I have the e...

Re: Position Based Dynamics: Patent

This second sentence assumes its own conclusion by assuming that an "owner" thinks of an "idea". I question this very premise of ownership. Someone can _originate_ an idea, but by virtue of originating it, does he automatically own it? What is the concept of ownership? I believe it means exclusive ...

Re: Position Based Dynamics: Patent

Well, I would argue (without offending you) it is immoral to discuss ideas on public forums (this was your intention with your original thread) and then even when you have done the major work to patent them or expand your patent based on this discussion. Right, but I didn't do that and have no inte...

Re: Position Based Dynamics: Patent

Thanks! By all means, let fly. I actually love to debate, and I promise I won't take anything personally. Anyway, this thread needed another side to be interesting :) so I'll be happy to play that part. First off I should retract / admit a mistake regarding the words "exactly the same". I concede th...

Re: FastLSM soft body physics (source code available)

Wow, I really was out of my depth here. Thanks so much for all the info you guys are providing -- I really didn't have much of an understanding of any of this (that is, the realities of patents). It seems I really blundered by mentioning patents at all. I've taken the step of removing the mention of...

Re: Position Based Dynamics: Patent

OK, so, to continue the discussion of patents: I'm very interested by all of this as it may have some bearing on my future conduct as a graphics researcher. First off however I want to say that I don't think patents are immoral. I think it's probably true that the patent system is broken, but I'm no...

Re: FastLSM soft body physics (source code available)

No offense taken. However, I think that the situation may be being cast in an inaccurate light. First of all, I believe that the comparison between ODE / Bullet and FastLSM is not a completely direct one (though it may still be a useful one), because the first two are software libraries, whereas Fas...

Re: FastLSM soft body physics (source code available)

I read the discussion of patents on another thread with interest. I think it's true what people say, that patents are annoying once the paper is published, but I believe most people (certainly including researchers working for companies, such as Dr. Mueller) would not publish the paper in the first ...

FastLSM soft body physics (source code available) original

Hello all, Just letting you know I have put up the source code for a programming library implementing the new FastLSM soft body physics algorithm, which was developed by myself and Professor Doug James at Cornell University and which was presented at SIGGRAPH 2007. The FastLSM algorithm allows for s...
