Recently,I should developed an app using vuforia. Here is the whole process.Firstly,the app should track face in every camera frame. However, the target is not the face. It is some object. Then it will compute a value based the recognized face which is different in each frame. Next,the value will be passed to the unity model and the cube height will be changed based the value.Finally, the cube will be rendered in the current frame.
In method renderFrameQCAR, vuforia will show the current frame, detect the target object, render the 3D model in current frame. I don't know how to achive my goal. Can anyone give me advice?
