3d rendering: uwp c# and c++

Question

3d rendering: uwp c# and c++

Gareth Williams 46

I have a uwp app written in c# - all is well with that.
I want to add a 3d rendering feature to render a trajectory of a projectile.
I understand that direct 3d is written in c++, I am very proficient in c++.
Since my app is c#, however can I incorporate c++ code into it to do direct 3d rendering onto the screen?

I have been looking at the 3d game sample project.
The app starts life as c++.
I am starting the other way around with c#

Is this possible with my existing app?

In UWP, 3D rendering can be done with SwapChainPanel

Thank you, if I understand from the documentation:

I add a new project into my solution of the type "Windows Runtime Component (Universal Windows) C++"

I Develop the direct3d code in that component

I put a SwapChainPanel in my ui xaml where I want it to be rendered

I pass the runtime component a reference to that swap chain panel and the data needed for the rendering of the trajectory

Am I on the right track here?

Yes
And you can see the sample XAML SwapChainPanel DirectX interop sample
I recompiled it by creating a new UWP project where I added all the files, + the DirectX part (Windows Runtime Component (C++/WinRT)) which is compiled as DLL/winmd then added as Reference :
