    Shading (fog) in Wolf4SDL Empty Shading (fog) in Wolf4SDL

    Hi guys, I've been hacking a bit with Wolf4SDL a bit (v1.7, is there a newer code base?).
    What bothers me is that in 256 color mode, you have to map colors to existing palette which
    makes shading look very ugly in some cases, which is a pity as I've seen it being used
    in lots of cool mods.
    So i decided to try to use 16 or 32-bit screenBuffer instead. There're still many problems,
    especially palette fades and so on. If time permits and if I find a solution I will upload
    the modified source somewhere. The rgb solution would allow to shade textures with animated
    palette (with some extra work of course) and i believe it would allow for new cool effects.
    Of course the drawback is extra memory and some performance penalty
    but Wolf4SDL is not intended for DOS anyway.

    original (8bpp, palette):
    Shading (fog) in Wolf4SDL Wolfpa10
    32bpp, rgb:
    Shading (fog) in Wolf4SDL Wolf3210

    I chose a bad area (and JPEG did its job - not my fault, the images i uploaded were jpegs with quality 100)
    but you sure noticed for example colorful textures going gray etc.
    So what do you think? Please let me know if something like that has been attempted before.
    I don't have much free time for this so no need to reinvent the wheel (btw. has someone tried mipmapping yet?)

    Very nice work, mar. I don't recall this ever being done before.

    Does it affect game performance at all?

    Thanks Andy. Yes there will be some performance hit. I will quantify it as soon as I finish it.
    I already solved the palette problems, but have some minor things to fix yet.

    With this way of shading, could you also make a level insanely dark? It's an effect I've always wanted to use but it doesn't look great with the old way of creating shading.

    Yes it should be possible. There's still some minor issues like ugly frame after get psyched and shading
    bypasses fade to red when killed (no easy way to fix).
    I also added nonlinear shade define to version.h, as well as 32-bpp mode define.
    The source along with precompiled windows binaries can be found here:
    http://www.mediafire.com/download.php?x4cpevlomlo7x7i

    Runs smooth in 640x400 on core2 duo/2 GHz.
    However, 1280x800 is not smooth even with original Wolf4SDL but still even with smooth shades well playable.
    I haven't tested floors/atmos effect as I don't know how Smile

    Here's final screenshot with nonlinear, 32bpp shades:

    Super late. Just discovered a thread in my own forum. Laughing
    Looks quite awesome. The shades of grey have been so standard in many mods, I got used to it. Hopefully newer mods won't have those bars of grey.

    I'm wondering if Mar still has the original pictures of "original (8bpp, palette):" & "32bpp, rgb:" on here.  I think that we'd be interested.
