    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 Visual Studio, .NET Framework 4.7.1. The Graphics.sln and Space3d.sln solutions contain test applications, called UnitTest, featuring the library capabilities.
