My little question :
Can you mipmap these guys ?
I think the answer is NO.
But how can you fix that ugly shimmering of the bumps on far away polys ?

Just don’t bump map if it is far away. You won’t notice a difference and it will give you a speed up.

But if you insist on bump mapping anyway, then I don’t know.

You got it georg
I was thinking of using different LOD EMBM maps. In a way, doing mipmapping by hand.
If anyone has a better idea… you’re welcome !

You can have mipmapping on the DUDV texture, I have it in my EMBM demo. But the gluBuild2DMipmaps() function wont recognice the GL_DUDV_ATIX format parameter … so you need to write your own mipmap building function, but that’s not hard … around 20 lines of code.

I’ll try this, I think can do a bitmap resize function
I was just wondering if anybody tried and if there were some artifacts. You gave me the answer, Humus !

Oh yes …
If you have a RadeON (only !) you can check this out : (2.04 Mb)

You have to get the latest beta drivers and disable anisotropy because it don’t work with EMBM.
You don’t need a GF3 to see a nice bumpy per pixel lighted sea scene

Tell me what you think !

Hey Paddy, could you post a screen grab of that ocean? I’d like to see it and don’t have a radeon :P.

The static image don’t give justice to the moving thing anyway.
Final will also include a sky with sun/moon/stars.

I will also use an alternate bump technology for NVidia boards.

Look absolutly sweet.

Better start doing some mipmapping for my bumpmaps

Waiting impatiently for the final version

On GF3 hardware, we support fully correct dependent texturing LOD calculations.

This publicity was brought to you by Nvidia

To Matt :
I would be pleased to support the GF3 with all it’s advanced features in our engine, but there is now way to find one here in France …

New version available
Featuring the Moon, and now nice mipmapped EMBM. Waves are better too (perlin noise) and they come and go …
Also, it’s a zip now (no longer rar).
The archive is big because of the 1024x1024 bump map … it will be procedurally generated in the next release

ENJOY IT : (2.92mb)

Someone told me the bug which makes EMBM crash if anisotropic is enabled was fixed in the Win9x 7109 drivers. Can anyone confirm this please ?? Thanks !

Yup, it’s gone.
