Space3d
C# graphics library used for 3D modeling, built with OpenGL/OpenTK
...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.
