Introduction to ramBaseRecognizer

In RAMDanceToolkit 1.0.0, ramRecognizer is an experimental class. There are many cases of analysis result which will be returned, so currently this class doesn't have a regular format. Please post an issue or send pull request if you have an idea concerning this class.

Current ramBaseRecognizer is empty:

class ramBaseRecognizer : public ramUnit {
public:
};

See also Notation scene as recognizer example.

ramGeometry

ramGeometry is used in Notation scene, Three Points scene, Four Points scene . To use these methods, include ramGeometry.h to header file of your scene.
