    Space3d

    Space3d

    C# graphics library used for 3D modeling, built with OpenGL/OpenTK

    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. All the project libraries are built with VS 2017, .NET Framework 4.7.1. The Graphics.sln and Space3d.sln solutions contain test applications, featuring the library capabilities.
