Create external dll and mesh render

Hi I would like to ask you if it will be posible to generate a dll from Unity to create a menu. In this menu I would like to introduce points with the (x,y,z) values and render a 3d object with planes, cubes and so... Pick every single element and change their colour.
It would be posible to call the dll from a project done in Visual Studio?
I would like to use the unity engine but just as support for my application.
Thank you

 

It is not possible with Unity, unfortunately. Or rather, technically you could do that, but it would break eula.

You may try to do such thing with some open-source 3D engine like Ogre3d or Irrlicht.

 

If you're asking if you can use Unity to create your own game engine... no. Like @darkhog stated that breaks the EULA.

If you're asking if you can use Unity more like an API rather than work through the editor, that's perfectly fine and is the way some people (like @zombiegorilla) approach the engine.

 

It's not possible as written. Mainly because unity outputs executables instead of dlls. But you can acheive the same effect.

Create an executable application with Unity. Launch the application with you VS application. Then use the various .NET tools to communicate between VS and the Unity app.

 

Communicating back and forth with .NET sockets would work very well.

 

Thank you for your support!
