The Graphics Library is built on top of OpenTK, the C# library that wraps OpenGL. The intended clients are technical and engineering graphics applications that require three-dimensional visualization tool. The implementation draws a scene on separate working thread, optionally, the thread-updater may be invoked. The Space3d Library uses Recursive Composition design pattern. The hierarchy by reference, built into the component, plays a dual role in modeling three-dimensional space: first, it provides a control over a lifetime of the object cluster; second, it mirrors a subordination of the object coordinate systems. The project libraries are built with Visual Studio, using .NET Framework 4.7.1. To test the graphics capabilities, compile and run the GraphicsTest solution. To test the Space3d Library, compile and run the Space3dTest solution.
