Russian 3D core zahabreno. Answers to your questions

Nikolay Snytnikov - Head of LEDAS-part of the RGK project. Specialist in parallel computing and geometric modeling, Ph.D. in Physics and Mathematics. He carefully read the discussion that unfolded in the original topic about the Russian 3D core and tried to answer the most frequently asked questions of Habrahabr readers.

Topics were raised about the difference of three-dimensional graphics engines from CAD cores, about Linux and Qt, "bicycles", and where does the state.

Since the answers in the form of a small article were published on another resource and in order not to incur the wrath of a UFO prohibiting the repost, I suggest that you read the answers on the Russian 3D-core link.

In general, I think such a situation is not logical and not convenient. When asking questions here, and answer there. A discussion with developers in one place would be more productive, in which more answers to our questions could be obtained. But we have what we have.

As far as I understand, the authors are ready and will be happy to answer further questions and possible suggestions - first of all, concerning the architecture, the methods used, the efficiency of algorithms and other technological aspects of the project.
