using emgucv and openTK

Hi!!
First of all, sorry if my english is bad, I am not a native .
I've been working with emgu cv(opencv wrapper to capture images from a webcam and using its functions to proccess this images.
I also detect the hand and track the hand movement...

Now, I need to draw a kind of earth or just an object according to the hand position, for which openTK is perfect for perspective transformation and so on. My problem is that I can't achieve that.

I don't know how to say to openTK "you guy, draw that object within this hand tracking window"
Is it impossible what I want to do? I am desperate... any help would be great. Thanks in advance
