Head pose estimation opencv

Question

I have a specific question with regards head pose, I am looking into creating a cylindrical model that maps 2D points to this 3D model, and then compare points from successive frames using optical flow,
so that later on I can perform pose estimation.

I discovered that opencv has a warp function http://docs.opencv.org/modules/stitching/doc/warpers.html#detail::CylindricalWarper : public detail::RotationWarperBase

I also have read that OpenGl might be used for this.

I think what I am looking for is a texture map, but here is an example of what I am looking for....

Any guidance would be much appreciated,

Thanks.

Here is a good tutorial to get you started:

I have modified this code in one project to create a realtime head pose tracker. The initial feature points were detected autmatically, and tracked along the frame sequence.
