Introduction

This project uses 2 infrared trackers and a tracking target that is attached to some android device. The data is collected from the trackers by CalVR in the form of a homogeneous 4x4 matrix which is processed by a CalVR plugin that sends packets using UDP to whoever sends a request packet. It is sent as a comma separated string and then unwrapped an parsed on the android device; stripping the position and axis column vectors.

On the android device, we are using the Min3D framework which is based on a scene graph and has excellent wavefront .obj file loading. When you first start the app, you a presented with a screen that allows you to choose which model you want shown. After picking a model, it should appear on the screen along with some information text in the upper left hand corner. Pressing the context menu button and then "Start tracking" will enable the tracking feature and continuously update the camera of the scene graph based on what we receive from the CalVR plugin.
