A sample project for integrating Gesture Recognition Toolkit (GRT) with Unreal Engine

GRTSample Unreal Project

A sample project which porting the GRT library into unreal engine module.

Build and test on VS2017 with Unreal Engine 4.18.3.

Notice: this is some old unfinished work, only DTW(Dynamic Time Warping) classifier will work

Why not just use GRT?

You can compile and link GRT with Unreal but there are many reason that they won't work together:

• Many macros get overwritten when link unreal with GRT header
• Unreal Engine use it's own data types to replace the ones in standard C++ library
• Unreal Engine also forbid developer to catch or throw the exception, it turns off unwind semantics by default.
• Unreal Engine has it’s own run-time type identification system and method like "dynamic_cast" will not work.
