Activiz is a cross-platform C# wrapper of the internationally renowned VTK library for processing and visualizing scientific data. It includes many advanced algorithms to load and process data, as well as state-of-the-art rendering techniques. VTK is used by academicians for teaching and research, by government research institutions, and by many commercial companies that use VTK to build or extend products. It exists for 30 years and has been downloaded more than 2 millions times. It can be interfaced in Unity, with hololens... The documentation and the example scenes shipped with this asset show how to set up a VTK scene within your Unity project.
