Pick intersection coordinate

Hi,

I have simple scene consisting of a quadarray which can potentially be rotated and moved and that has a simple texture applied. How can i get the coordinates on the quadarray if the user clicks it on the canvas (i.e. i want the click point on the actual quad not the canvas)? i think this is the pick intersection point with the quadarray? basically i want the point so i can update a few pixels on the quads texture at the click point. Sorry for the poor explaination, I'm not quite sure how to explain. Any help appreciated!

Cheers :)
