Self shadowing bumpmapping demo updated with offset mapping

[Humus]

Now the really fun part would be to see if you can manage to accurately combine this bump mapping technique with a global shadowing technique (i.e. shadow buffers, shadow volumes).

I think that it shouldn't be too hard to combine with shadow mapping at least.

do you use the ps2a profile for gffx cards?

Yes, he does.

ok thanks.

Longest thread title in history

Good thing you don't live in Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch.

hahahahaha I had a welsh friend wayback in high school whom could actually pronouce that.

Here's another shot still on Volari

i don't know but i think something with the lighting is wrong

Maybe it depends on the angle of the light 'cos this one looks like Doomtrooper's pic :

Humus, could you please comment?


BTW, the Volari card used is the low end version (it's single chip only) - having half the pixel shader units of the Duo or the 9700 doesn't help either...

 

[Doomtrooper]

Yep for sure, the more DX9 capable cards out there the better
To me it looks like the shadows are different, do you have everything enabled..check by pressing F1.

You shouldn't extract this .zip into the same folder as the old version of the demo

D'OH! Sorted now, working fine.

Humus, is the floor supposed to be wet/waxed?

How do I control the light?

Once again, VERY NICE humus. 8)

Now all I need is a big gun and stuff to shoot at!!

It looks like attenuation doesn't work. I'm not sure I'm seeing any self shadowing on the brick either, but it might just be the angle as it seems to work on the floor.

You don't
Well, shader editing is always an option. You can reduce or remove the specular if you want it less shiny.

Just tried it with 0.1 specular - IMO that looks better, especially for the bricks. But either way - simply awesome.

strangely, i get a "Couldn't create a Direct3d Device Interface" error.
Yes, i am using the CAt 3.10's, and all my other apps work - including your recent cloth simulation - but not previous version of this demo. It crashes with the same error (tried both individually)

OK, i fixed it - its quite odd.
I had to go into the registry where you store your values, and set "fullscreen" to 0.
THen the demo worked fine - even when i chose to go into fullscreen mode. how strange - you might want to look into this.

But, really, what makes this "more (and more) interesting" is basically the specular aspect.

Why do you think I asked the 2nd question?

That's the problem, as I'm sure you (& et al) knows.

 

[rwolf]

Well you can add this to Humusmark 2004.

 

[sonix666]

I really like that idea. Make a benchmark of all your nice shaders Humus, and make the peeps at Beyond3D use it in their reviews.

Well, I'd really like to see it done It doesn't seem obvious to me how you'd use the same displacement technique to get whether or not a pixel is in shadow by displacing it in the direction normal to the surface.

And, of course, then the next step would be managing multiple light sources properly....though that shouldn't be all that big of a deal, I don't think.
