I have downloaded udSDK in order to evaluate the point cloud visualization inside a simple application written in C++ in the Qt environment.

I have tried to implement the cpp sample in https://github.com/Euclideon/udSDKSamples/tree/master/languages/cpp, but everything I get is a tmp.png saved in the exe folder: it's not clear to me how to render, for example in a QWidget, or even in an external window, the 3d scene. Can you please give me some advice?

Thank you in advance and best regards,
