Hello guys!
 
	I must mention that I am new, and that I am Latin, so sorry for my English.
 
	 
 
	Okay.. my question is the following.
 
	How to collision normal image and polygonal image.? 
	What a clash with each other.
 
	 
 
	In short, that's what I need to know.
 
	 
 
	I hope you can help me, thank you all!.
