Hi!
I want to use a skybox in a d3d based application, but i can't disable the clipping... so i have to use a small skybox, and the
result is quite ugly: the user can really see that the sky is a box!!!
please help!!!
(i'm using dx8)

Could you give a bit more information on how the skybox appears to the user. I'm not sure how to take your "the user can really see that the sky is a box".

Nevertheless, have you considered using a skydome instead -- it certainly doesn't exhibit those sharp edges like the box does.

regards,

well, the skybox is nice, but to be rendered properly, i should scale it with a great value (it should be an infinite). but if i do so, the box isn't rendered anymore cause of the default clipping. and i still don't know how to disable it.
thanks,
Ralph

There are two possibilities for you: Either you turn on/off clipping partially with a call to

IDirect3DDevice8::SetClipStatus

specifying particular planes or you turn off clipping altogether using

IDirect3DDevice8::SetRenderState( D3DRS_CLIPPING, FALSE );

Did that work for you? Hope you are progressing :)

IDirect3DDevice8::SetRenderState( D3DRS_CLIPPING, FALSE );
but it still hide my box if it is to far away...

That's strange -- on my system the IDirect3DDevice8::SetRenderState( D3DRS_CLIPPING, FALSE ) works just as expected. Have you checked the return value using the SUCCEEDED/FAILED-macros to see whether it is really disabled? You can also use
DWORD dwRet = 0;
IDirect3DDevice8::GetRenderState( D3DRS_CLIPPING, &dwRet );
before drawing your skybox, to see if clipping might have been enabled at some other point in your application.
