Try PCSS

How did you calculate the inverse tangent space matrix for normal mapping? I can't figure out for the life of me how to do it.

@manyalforever I have updated the video detail, you can now find a link with the source code used for this video.

Excellent work!

[superkellerman8D]

where'd you get the doom 3 models?

[ocmpadm0]

@superkellerman8D From the game, they are in clear text.

Looks cool. But I don't really see much softness in the shadow.. I can't really see the penumbra of the shadow ..

yaya man!!! looking awesome

[captainclayman]

dude this is really good

[arkano22]

Very very nice!

For PCF and PCSS i´m using dithering and it looks good. However things can be much more smooth if you render your shadows to an off-screen buffer and then apply them a bilateral blur filter. That way the sampling artifacts disappear almost completely.

keep up the good work!

I really don't like the results of that screen-space shadow blur.

Shadows tend to spill from behind over things that are fully lit. It looks "photoshopped" if you get my drift.

It would have to be a very faint screen space blur, but I guess that doesn't help take away the sampling artifacts.

Man you're a genius! This test is awesome! I'm trying to learn to program with OpenGL and your works are really inspiring for me! Keep up with great works! Thanks a lot!
