Hi Everyone,

I am trying to implement an OpenGL eraser tool. I am struggling with this. I was thinking of painting somehow over the previous changes to "clear" out the changes. I can't use the background color because it is not a pattern, not one solid color. Can you point me to the right direction on how to implement an eraser tool ?

This is for the iPhone OS but that shouldn't matter.

Thanks
