what's up with the fancy html e-mail ;)
someone body from ensemble studios wrote about there problems and how they
got around the color restriction they had.
check there web site. there's a ppt up.
also gdmag had an article written by an ensemble guy as well.

i'm not sure how a 3d pallete/game versus a 2d pallete/game is going to work
out. imho your going to more worreid about getting your shading right
instead of showing the "vibrance" of the few colors you have ;)


peace.

isn't it ironic, in the paper "A Characterization of Ten Hidden-Surface
Algorithms", by sutherland, sproull and schumacker that we use the eleventh
algorithm ;)
makes you really think

    This is going to depend on how you are going to use the colors - match
offline, or generate shading etc at runtime.
For runtime you should find examples in the Windows OpenGL code (in the
Visual C++ docs) for producing a palette for effectively 3/3/2 color depth
from a palette. This does leave a few free entries (normally used for
Windows) that you can use for huds etc. The results are pretty horrible
though....
    If you can generate a big 24 bit image containing the colors you know
you are going to need then I'd suggest doing that and generating a palette
from that to use. (I'd recommend Wu's version from Graphics Gems. Much
better IMHO than Octree etc.)
    Could be worse - I still have memories from color clash on the
Spectrum... getting to 16 colors in bitplanes on the Atari ST was heaven :-)

Hi,

Can any of you guys give me some hints on choosing a decent 256 colour
palette so that I can get a nice spread of colours.  I need it for a simple
3d game so basically I need to cover common colours and shades thereof.

Do any of you have experience in this area.  I've had it so easy with 24-bit
graphics up until now!  :-)

Thanks in advance for any help that you might provide.

Cheers!
