The current release, and the next one (2.01) are free and will remain free. There is no fee and no donation is required.
The DLL is nearing the point where it will become a professional grade system. Handling very intensive processes.
The planning and construction of the system is very intricate and consumes a large majority of time. And therefore, we cannot afford to continue to develop the system at no cost after version 2.01
We do understand the from the developers standpoint this just looks like "simple collision". But in fact, the actual collision detection is only part of the system. Much time is spent designing how memory will be handled, as we intend it to be used for the largest and most intensive of projects.
This will allow people to integrate the collision system with Visibility sets of massive worlds, etc. And the collision system must be full proof without sacrificing FPS. We would like to go even as far as an integrated DataBase system, so unused sections of a world can be de-activated and removed from RAM.
We will try to keep the DLL inexpensive for all users. Probably around the mark of $15 for a user or team. And they can use it on as many projects as they like with no royalties or anything. And it will come with the blitz copy too, so you get a package deal.
We believe, that for the quality of the system when we release it, the purchase fee will be fair
