Snow by m0jo

Being a skiier I know what real snow looks like, and that looks just like it. Great job

And a suggestion, could you make areas of the picture that stand out gather piles of snow on them? Because that would be really cool.

Ok so after 5 minutes of working on it I found a way less intensive way to do it

It needs some tweaking to get a realistic snow deposit texture, right now it's too smooth and rough edged at the same time.
I wish there was an Anti-Alias component, so that you could force some in between light Anti-Aliasing on certain parts only!

Also I need to find a way to make it work on less perfect foto's than the Lifesaver.
If I stick a normal picture in now, the snow buildup is perfect in some places.. wrong on other places.
I think I can't get this perfect for all pictures, so a way to tweak this to suit a certain picture would be best I think.

Here's my current working version:

Snow.ffxml

Great, I will look at it too when I have more time.

The most important part is to determine where the deposit should occur.
I think you can use shadows to find places where snow should build up.
But then you need to offset .. and then you have a problem due to perspective (which the Lifesaver doesn't have that much).

So finding shadows and then finding a way to shift upwards is the challenge I think.

My version turned out like this on some tiles.
