Thanks to the SCP Freespace 2 now has the enviromnental mapping. So what about bump mapping ? Is it possible?

For those who don't know what I am talking about:

We're getting there, bob has IIRC alraedy created a system in wich bumpmapping could be implemented, or somthing to that effect.
actualy, mabye not.

Bump mapping is waiting for an overhaul of the texture system. At the moment FS2 has to make repeated passes in order to put in all the features we already have. Adding bump mapping or normal mapping would require yet another pass which would slow the game down even more.

The overhaul is going on at the moment though so don't that it's just an excuse :)

actualy the texture system isn't the bottle neck for bump mapping, I do intend to implement a shader system that would allow bump mapping sooner than later, but this wouldn't be the first progect of mine to fail.

When bump mapping is implemented, I'm going to cry. I promise. ;)

As long as you can tell the difference I will too.  But if it's implemented like it is in Renegade , I'll smack you....;)

One question: can anyone tell me the difference between Bump mapping and Environmental bump mapping ? Is it the same feature?

environmental bump mapping is a different version of bump mapping. it simulates bumps by shifting the reflection map over by a certain amount in specified areas.

G4MX doesn't pixel shaders, which if IIRC, is a factor.

Err... doesn't DX8 do Pixel- and Vertex shader, too?
I've an "old" GeForce 3 which already have those features...
And AFAIK DX8 should already support this...
Well... Okay... DX8 Supports the GF3 version of shaders (version 1.1?) and for higher shader versions we really would need DX9...

Wait... OGL can do that, too ;)

Problem with Direct X 9 is that you would have to have a video card that supports it. ;)
