That's only one-side of the story. It is actually a very accurate contact model. The problem is that it's also computationally expensive and therefore we reduce the stiffness of objects to make it faster. It's basically a trade-off between the accuracy and speed.
In gaming engines you have speed and it looks good, but then it's impossible to generalize for real-life applications (because the contact is inaccurate).
I am sorry, I didn't mean any legal accusation - it just feels a little odd that the description of the app sounds as if you invented the technology without ever referring to the original work.
"Stiefvater [...] described it to me as 'black magic,' and doesn’t even fully understand how it works. He downloaded it from Github, where a computer programmer he’s never met posted it."
Thank you very much! As these are recent changes which we haven't tested live, your comments are very useful and we are actually implementing them now.
Given that we are discussing it in the comments of the app who just misappropriated the algorithm, I unfortunately have to refuse your request for the moment, sorry. We love open research and open source but there is always some risk involved.
Definitely it all requires more explanation as we take it for granted but for users it is not clear what is happening
Unfortunately "I want it now" is not possible for the moment as the computations are really heavy and there is a lot of people who want to use it. But we also have some ideas for that.
Now our focus is the quality, regardless the cost. We increased the resolution and we try to make things faster. Later we will figure out how to make it more sustainable.
Good point, thanks! We actually had one, but we removed it in the current version (it seemed natural for us but it obviously is not) - we will bring it back.
We simply have limited resources for servers, but still want to provide the highest quality possible in the free version. That's why there is a queue, but we are working hard to make the implementation faster and more efficient :)
