Hi there,
I need to create this kind of effet:
The user draw on a black surface with his finger
The image behind the black surface appear where his finger draw (like a drawing path)
Its like removing a mask with the finger… Not sure to be clear 
I look at the mask feature but it is working with a bitmap file only.
Any help is welcome.
Hi @dmekersa,
A developer created something similar to this using Graphics 2.0, where the finger would “erase” a layer of fog over an image. But in my searches, I just can’t seem to find the post that talked about it. 
Anybody know where that post went? If so, please post it here.
Thanks,
Brent
Hi.
I don’t know about that other code, but I have something that sounds like what you want (which I was just looking at, actually).

It’s a scene file. It might behave like you want if you put the image down before InitCells() and change R, G, B to black. It basically puts a bunch of pixels up and then masks / unmasks them.
It was just testing code, though, so there are obvious issues like drags breaking up on fast swipes and some mask scaling artifacts (and the mask shape is still too round for my taste). But maybe it’s a starting point.
Thanks a lot!
I’ll give a try, it should help a lot!
