Вот с news.rhino3d.com Bob McNeel: Our license for AGLib runs out on Dec 31, 2002. Knowing this, we did not use much AGLib technology in Rhino 2.0. In fact, the only thing that was a big problem was that the AGLib data structures were used everywhere. That is one reason, Rhino 3.0 is a complete ground up rewrite. Rhino 2.0 still uses a few AGLib functions, but nothing major. All of those should be replaced in the next few weeks. Also, AGLib is very old code by today's standards. We would have replaced all of AGLib and rewritten Rhino 3.0 from the ground up without the contractual deadline. For Rhino 3.0, we are focused on the new core. Many new Rhino 3.x feature will not appear until after 3.0 ships, but with the new 3.0 architecture, major new features will not require a new core product release. We'll be passing on more details once the first Rhino 3.0 beta is ready. Бета обещается не раньше июня.
