I am a bit confused with how the image plates (both right and left) and the two eyepoints are set in a stereo head mounted display setup. 1) Eye point policy is completely nullified when tracking is enabled. correct? 2) Even though we are using stereo, we still should have one Canvas3D for a particular HMD. The Canvas3D object has methods returning information for one image plate (i.e. getImagePlateToVworld,getLeftEyeInImagePlate, etc.). Since the Spec (Appendix C.3.2 p.513) states that the two image plates (LCC and RCC) do not necessarily lie parallel to each other, what does the Canvas3D return? Does it return a image plate located at the head tracker that we can compute the LCC and RCC by simply taking the Transform3D that we have given to Screen.setHeadTrackerToLeftImagePlate? 3) To add onto #2, A stereo HMD consists of two screens, but the canvas only has one Screen3D object (Canvas3D.getScreen3D()). I guess if anyone can clear this up, I would really appreciate it! 4) It looks like the functions setHeadTrackerToLeftImagePlate and setHeadTrackerToRightImagePlate not only move the Image plate, but also places the eyepoint. My question is: since Eyepoint Policies are disabled in Head tracking mode, how do we set the eyepoints in HMD mode with tracking enabled? I know I either want to place them with respect to the Tracker or the Image plates, but I am not sure how to do this.
