kinect_dev replied to Hyunkel's topic in Graphics and GPU ProgrammingThese are awesome points. Thank you for posting these. I am not the original poster but I'm trying to do a similar thing and your answers have been very helpful.
kinect_dev replied to Hyunkel's topic in Graphics and GPU ProgrammingI've been working through the head tracking projection problem recently as well. One thing I noticed is that some of the online samples use DirectX's LookAtLH and PerspectiveOffCenterLH. These are left-handed versions of the common way to create a View and Projection matrix. When using XNA, however, there are not left-handed methods available. CreateLookAt and CreatePerspectiveOffCenter are right-handed versions of those methods. I'm not totally sure how to convert from one to another; it's possible that multiplying the z-coordinate by -1 might do the trick.
