Introduction to ramBaseRecognizer

In RAMDanceToolkit 1.0.0, ramBaseRecognizer is an experimental class. There are many kinds of analysis results that might be returned. Because of this, ramBaseRecognizer doesn't have a uniform format. If you have any issues with this class, plesae create a new issue or send a pull request! ramBaseRecognizer is still a work in progress :)

The Current ramBaseRecognizer implementation is empty:

class ramBaseRecognizer : public ramUnit {
public:
};

For an examlple of how to use a recognizer, please look at the Notation scene example.

ramGeometry

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

void rotateToNormal(ofVec3f normal);

void approximatePlane(const vector& points, int iterations, ofVec3f& center, ofVec3f& normal);

---

ofVec2f closestPointOnRay(const ofVec2f& p1, const ofVec2f& p2, const ofVec2f& p3);

---

ofVec2f closestPointOnLine(const ofVec2f& p1, const ofVec2f& p2, const ofVec2f& p3);

---

ofVec2f closestPointOnRect(const cv::RotatedRect& rect, const ofVec2f& point);
