Under “Karamba.Geometry” one finds the geometry types of Karamba3D. In most cases the K3D-equivalents of a GH geometry types come without the “D” at the end: e.g. Grasshopper’s Vector3D is equivalent to K3D’s Vector3. The static class “Karamba.GHopper.Utilities.FromGH” provides typeconversion from GH-wrappes (e.g. GH_Vector) to K3D types. The namespace “Karamba.GHopper.Geometry" contains the classes MeshExtension and MeshExtension which extend the GH and Karamba3D geometry classes with the “Convert” method for bi-directional type conversion.
