Subject: Quake tools in C++
I'm interested in writing some Quake tools in C++, preferably using
the C++ Standard Template Library (STL). I'll be developing using
Win95 with memory mapped files. Are there others out there with
similar interests (i.e. using C++ rather than C)?

The Quake palette is a simple array of 256 * 3 bytes (RGB). The palette
is stored in gfx.wad. Take a look at "LoadPalette()" in QEU 0.3 (in the
file f_bitmap.c). This should show you how to use it. You can also
compile "unwad2" and see how it saves the palette in BMP files.

I know how the palette is set up, but when I use the palette from the
gfx.wad the textures do not look right. This leads me to believe that they
are using a color look up table for the texture. So, do you know if the
textures reference the palette directly, or is there is an intermediate
color quantization table? It could be that I have just set the palette
wrong.

I just fixed the problem. I was setting the palette wrong. The palette entries
are in the range of 0-255. The VGA DAC only accepts 6-bit entries so I had to
right shift all values by 2 before setting the palette.
