Denis Shergin, the CEO of Unigine Corp is interviewed by Phoronix. Unigine Corp size is 12 people (including 4 programmers, one designer and one technical artist).

Unigine engine has its own scripting language called UnigineScript, which is an object-oriented fast language with built-in 3D math support.
They plan to use OpenCL for physics simulation and rendering acceleration only if OpenCL performance will be good. In the OpenGL side, the Unigine engine has different code paths for graphics rendering, because the same feature can be implemented differently in ATI / NVIDIA hardware, plus it provides a performance boost.
