Nice one! This adds a really nice feeling to the scene.
Also!? Have you ever released the code for your other article at http://www.gamedev.net/reference/articles/article2032.asp?

Keep up the good work!

Hello,

I just implemented this in my 2D DirectX game, but I have one question?
How did you handle images with alpha values?

I had to add this check to the depthmap creation:
if(color.a > 0.1f)
return float4(1.0f-CurrentDepth, 1.0f-CurrentDepth, 1.0f-CurrentDepth, 1);
else
return float4(0, 0, 0, 0);

Yet, I’m not quite satisfied with this.
Anyway, you can see my results here:

After: http://img37.imageshack.us/f/afterh.png/

This is after applying a box-blur over the texture.

Oops, my mistake. Should be fixed now, ta.

From the sourcecode:
for (int i=0; i 0.01)

Which might be:
for (int i=0; i LT ??; i+=0.01)
so what’s the upper bound?

Maybe add html-encoding to see LT, GT, EQ?

Wow, that’s…that’s really quite cool

Well done! I really wanted to get shadowing into Mop of Destiny, but I couldn’t come up with a good way to do so. I wish I’d had this at the time! Maybe for the sequel…
