artoolkitX has a number of application programming interfaces (APIs). This page gives an overview of the APIs available and their high-level layout and struture.

The main APIs are:

• The primary high-level API in artoolkitX is a C++ exposed by the ARX library. Add #include <ARX/ARController.h> to your C++ source.
• A full-featured simplified C API is also available to the ARX library. Add #include <ARX/ARX_c.h> to your C/C++ source.
• A Java API is exposed in the ARXJ project. It is implemented via a JNI interface to libARX.
• A C# API is exposed in artoolkitX for Unity. It is implemented via a P/Invoke interface to libARX.

The ARX API deals in a number of key abstractions:

• controller
• videosource
• tracker
• trackable
• videoview

#include <ARX/ARController.h>
ARController *c = new ARController();
c->initialiseBase();
ARTrackable *t = findTrackable(c->addTrackable("single;hiro.patt;80.0"));
c->startRunning();
while (!done) {
 if (c->capture()) {
 c->update();
 if (t->visible) {
 draw(t->transformationMatrix());
 }
 }
 }
}
c->stopRunning();
c->shutdown();
