For this chapter, we will modify our existing ImageDetectionFilter class. We will also add files for the following new classes and interfaces:
com.nummist.secondsight.ARCubeRenderer: This class represents the rendering logic for a colorful cube that sits in front of a tracked, real-world object. The class implements theGLSurfaceView.Rendererinterface from the Android standard library. The projection matrix is determined by aCameraProjectionAdapterinstance, and the cube's pose matrix is determined by anARFilterinstance, as described later.com.nummist.secondsight.adapters.CameraProjectionAdapter: This class represents the relationship between a physical camera and a projection matrix. Other classes may fetch the projection matrix in either OpenCV or OpenGL format.com.nummist.secondsight.filters.ar.ARFilter: This interface represents a filter that captures the position and rotation of a real-world object as an OpenGL matrix.
