You can find it here. It has shadows and a Linux binary now...

The linux version definitly needs some work regarding mouse control...
The mouse-pointer was jumping around wildly on my desktop, sending clicks(!) even though I wasn't pressing a mouse button. As a result my IDE closed, my browser closed...

The keyboard layout is tricky to use... I think 'wsad' or cursor keys would be easier.
For standard mouse controls 'left-right' should rotate around the world-y-axis, 'forward-back' should tilt about the player-x-axis. Right now you seem to be rotating about player-x + player-y which leads to confusion...

Other then that nice work!

It looks good. The only complaint I have is when the lighting is on my framerate SQUEALS in pain. I go down from 60 with no lighting to about 20. I don't know if that should happen, but I'm running a GeForce 4 64Mb, so I don't know. Just to let you know, keep up te good work!

@Wildfire: The mouse problem is really strange... Could you give me more info (Linux distribution, GFX card, libSDL version...) ?
I know the keyboard layout is strange, but "esdxrc" does not depend on qwerty/azerty-ness of the keyboard (and they are kindof placed the same way as the arrows on the num pad).

@Alray: I think the per-pixel lighting doesn't work on your GFX card (it probably displays as a "no lighting" mode with shadows): that would be even slower... I still have to optimize shadow volume rendering...

Anything I'm missing?

Mmm not quite, it looks different, but I just checked something. The thing that REALLY is lowering my framerate are the shadows not the PPL.

Here's some pics:

It worked for me on debian linux.

nice, btw.

Nice one [grin]

It needs some depth correction when parallax mapping is enabled and when the camera is close to the walls, apart from that it looks very good.

Congratulations ! KUTGW

I'm just wondering how your doing your shadowing... It looks to me, due to the performance hit at certain views, that you are casting a complete shadow volume off ever single triangle (brute force) - not using shilouettes..? is this correct?

Also, at least on my card, the specular seems to break quite nicly... as it projects off into the distance in one direction.. But I actually have a feeling there is something wrong with my system, as I've managed this myself with a perfectly good shader (was Cg, worked fine in GL, did this in D3D) - and theif 3 does it sometimes too....

hmm :)

You're right ! I first coded optimistic silhouette extracting stuff, but the result was bad with this model (there are a few unconnected triangles, see screenshot below), so I render a shadow volume for each triangle that faces the light.

I'll code some intermediate solution whenever I have time...

Could you post screenshots for this ?
