%description
A library of source code for computing in the fields of mathematics,
graphics, image analysis, and physics.
The engine is written in C++ 11 and, as such, has portable access
to standard constructs for multithreading programming on cores.
The engine also supports high-performance computing using general
purpose GPU programming (GPGPU).
SIMD code is also available using Intel Streaming SIMD Extensions (SSE).

GTEngine requires OpenGL 4.3 (or later) and GLSL 4.3 (or later)
in order to support compute shaders and GLSL introspection.

This is new version of Wild Magic 5 Engine.
