Name Spaces in C# and how to access external libraries
BACKGROUND
I have a free trial of unity pro, and am using QCAR augmented Reality. I am new to C#, (but well versed in JS), so I would appreciate some help using namespaces.
I want to use the method called projectPoint, described in the QCAR documentation here: https://ar.qualcomm.at/qdevnet/api . projectPoint usage is below:
QCAR_API Vec2F QCAR::Tool::projectPoint ( const CameraCalibration & calib, const Matrix34F & pose, const Vec3F & point )
QUESTION
How can I call this function inside C# script? And, what are the necessary imports/include(s)/namespace requirements?
PAST ATTEMPTS
Note, QCAR has been properly installed because the demo code from Qualcomm works fine. However, they don't use projectPoint or any similar function so I couldn't learn the usage from the samples.
I have tried and get the following errors:
include QCAR (Error: QCAR is a type, not a namespace)
using QCAR::Tool (Alias QCAR not found)
just executing the function in my C# class, I also get errors:
QCAR.VideoMode videoMode = QCAR::CameraDevice.getInstance().getVideoMode(CameraDevice.MODE_DEFAULT); (The nested type
VideoMode' does not exist in the type
QCAR')QCAR::VideoBackgroundConfig config = QCAR::Renderer::getInstance().getVideoBackgroundConfig(); (error CS1525: Unexpected symbol `::')
Could somebody please suggest how to improve this question...I'm getting stuck and don't know how to get around it

The code in your question is all C++. Is it possible that you are trying to link/include a C++ library from C#?
If yes, then you would have to find a wrapper dll which exposes your QCAR-library to .NET. You could also write your wrapper library yourself if one does not exist.
This is just my best guess without knowing QCAR. :)
You are correct. I posted on the QCAR website and they said the same thing. I have to wait until the new QCAR docs come out for unity. Thanks.
