Amazing Bump/Displacement Demo...can we do this?
Zoom into the maps, close...
press "T" to change the maps...
FYI- the bricks are NOT geometry...its all maps.
you can view the texture, bump and normal map with the demo.

Here is the Demo:

Here is the Glut, unzip to demo if needed

Here is the Thread where I found it

man, are you crazy? talking about amazing bump, showing off this picture first. i got blasted away, thought the next would be the code, thought you made a shot from 3dgs and was totally "baff"(german word:-).

but yea, if we had this kind of bumpmapping(to me it looks like displacement if there wasn't the flat edge)

cYa, hope we get this

sorry about that... i cant edit the post to specifiy that its not an A6 demo. Thats why I added the question "can A6 do this?"..so people would immediatly know...
I bet ventilator or Matt can figure it out...

i did a quick search for "directx displacement" , but it turned out to be directx9 feature. if i got it right. i hope i am wrong

i wouldnt have been shocked if that line was on top

Well, since you refernce GLUT as being needed, this is an OpenGL demo, and not DirectX. It might be possible to do the same things using directx, but it wouldnt be as easy as porting from a directx demo.

And, no, I dont know if Bump/Displacement mapping is available in directx 8.1, although I believe the fixed function pipeline does have some sort of bump mapping suppport ( or something like it).

After looking at the opengl vertex/fragment programs, they look like they should be doable, although the fragment program (pixel shader) might exceed the instruction count for directx, but I guess that would depend on which ps version you want (can) use.

the demo didn't work with my gf4 but on the screenshot it looks like an ordinary normal mapping effect to me! should work with a6...

oh! i didn't notice the displacement at first. the bricks really seem to overlap. i don't know how that works. probably that's a directx9 feature?

You will need DirectX 9 to accomplish exactly that. The transfer from OpenGL to HLSL isn't that difficult though. I believe the earliest version of shaders for DX that would accomplish that is pixel shaders 2.

Very nice all the same - it will tend to slow things down a bit though. Also, very very few video cards right now can handle it.

The demo looks very nice! I wish there were better navigational controls so that I could better view the effect from the angles I wanted too. I also noticed that my computer really slows down as I get very close to the effect (i.e the wall) but the speed is great when the entire scene is in view. Interesting.
