Hi all,
How can I use the latest vtk in my .NET c# application without ActiViz .NET ?
I gather ActiViz .NET is not open source anymore so what is the proper way to get VTK for my application? I am simply working in an academic setting for personal learning and projects.
Thanks
GT

Hi @gregthom992 ,
I’m afraid the free version of ActiViz .NET has been discontinued indeed.
I’d suggest contacting Kitware with your needs to see if a solution can be found for you:
> **[ActiViz - 3D Visualization Library for .Net C# and Unity | Kitware](https://www.kitware.eu/activiz/)**
>
> Unleash the power of the Visualization Toolkit for your 3D content in C#, .Net and Unity Software. Integrate 3D visualization in your application easily.
Best,
