Connecting Unity to external software

HI I have an idea of for a game/experianice that involves integration of 3d party software. For example I would like to take informations from camera and analize them is in3d party spoftware and send results to unity as, bools, floats, What software should I learn or what languages I need to know to do It. I can script in Unity but have No exp with intergration of dll and so on. What if i watned to Get into Users. browser history informations and use it for data evaluoation in 3d party software that would be sent back with results to Unity…

Some clever software analizes diffrent type of data, then sends results to Unity, Unity Sends its results back to Clever software, then clever software recalcuates and sends once again results to unity…

I can learn pretty fast but, no amount of self learning can speed up the whole proces as good advice Best regards

Unity has access to most of the .NET library. So the methods that work in .NET will work in Unity.

Here is your starting point.
