Hi, the new version don't crash, but this is what i see:

in the distance on the terrain there are shadow fields.
Graka: geforce 7600 gt

The demo works great with a constant of 60 fps
But the reason I thought more depth maps would cause more aliasing is because you use conditional requests (if-else branching) to call them. Thus an import remark is that conditionals in pixel shaders can cause aliasing and since you're planning to use 4 depth maps, the amount of conditionals requests will rise and so will the aliasing effect

Okay, I didn´t know that frazzle

For those with just one big black shadow: I think that your graficscard doesn´t support 1024*1024 pixels rendertargets.
At the moment I am trying to figure out the reason for the missing transparency...
ellos problem is a bit strange -_-

But anyways, here is a new screenshot:

hey slin that looks cool now. I love your work with shadowmapping. But I am too lazy to get in there

PS: if you are ready with that you have to start with that..."so-farer-away-the shadow-the-more-bluring-thing"

The latest version works for me, but I´ve got the same problems as Rasterbar.

Okay here is an other demo. It should work for most of you but with the costs of a lower quality. This demo uses a depthmapsresolution of 512*512 and 16bit floatingpoint format. The version before used 1024*1024 and 32bit floatingpoint...
The lower depth causes some artifacts in the variance part but I already have an idea on how to reduce them
I included a firstperson camera and I added some animated boxes Lutz_G gave me for that reason .
And as he proposed I now fade the shadows out in the distance.

This is what this version looks like:

Would be nice to give us a way to tweak this variable.
Apart from the artifacts it runs well at 75 fps.

Lol, doomstyle


At least no odd black squares anymore just low fps and blocky shadows ^^.

As for the fps, I still get a constant of 60 which is a great point but it would be even better if those annoying artifacts would be totaly
gone The shadows are great, no doubt about that but I still reckon that with out the use of conditionals, you would get a scene with better visual content thus without aliasing effects
I found an article which covers anti-aliasing through centroids, can be handy.
