This tutorial introduces the C# .NET implementation of the real-time protocol for QTM. The real-time client SDK allows you to stream, 3D, 6DoF, and other types of data from QTM. You can stream the data in real time or stream processed data by playing a recorded file. Beyond just streaming data, the SDK also allows C# programs to take control of QTM and do things like start and stop capture, which can be useful for creating applications that interface with QTM. This tutorial demonstrates how to connect to QTM through C# and how to get started developing.
