Haven't hear about paralax maps, I will check them out.
I know what displacement maps are, but haven't really seen them used in a way
that I think looks good. But I will look into that too.
Thanks Alan, =)

oh but other maps you might be interested in hearnig about, try googling these:
paralax map
displacement map
and if you run across this:
height map
that one is actually a different kind of map, not the kind you are thinking
about, a height map is just a way of representing terrain (mountains, valleys,
sand dunes etc) (:

Yeah
mip mapping is usually taken care of by the engine although i think sometimes
the artists can specify # of mips for specific textures.
Basically, in a 3d game, the video card has to be able to render textures at
different scales (as you notice, when something gets farther away from the
camera it gets smaller...).
It can do this one of 2 ways..
#1 - scale down the image on the fly every frame (this usually either results
in textures being scaled quickly so that they are ugly, or results in frame
rate dropping because they are scaling the textures nicely which takes longer)
#2 - Scale the image a bunch when it's first loaded and store the scaled images
in memory. This is called mip mapping and lets you scale images nicely (ie
bilinear or trilinear filtering etc) and store them in memory. This makes it
so you use more video memory but scaled textures look better and the game runs
faster.
Im curious, what has you investigating mip maps? (:
and btw, mip maps are not the same kind of map like specular maps and normal
maps are, it's a completely different kind of thing.

Hey Guys,
Another question, does anyone know much about MIP mapping? I get the general
concept of what it is/what it does, but I am wondering if it is applicable in
our situation, or in what situation/game it would be applicable...
Gonna google it too, but any info you guys have would be much appreciated. Its
always better from a artists point of view. =)
Thanks
Katie

Hey Katie,
Currently I'm upgrading the editor but after that I'll be moving back to
graphics land and upgradin our graphics.
Milkshape supports NO maps.
Our game however currently supports normal maps (doesnt look like it should
cause it needs an upgrade but it works).
For now we (Kent or I) have to set up the loading level script to apply the
normal maps to an object (which is no problem, nothin to worry about there)
In the future, you'll be able to apply the normal map from the editor.
Now because you are asking about other kinds of maps like specular maps, YEP we
can do those!
The game doesnt currently support them but specular maps for one should be not
too hard so feel free to use them (:

I think the kids need more maps, there just arent very many maps....=) ANYWAY,
Hey Guys,
I was wondering about what kind of maps the game/milkshape supports, IE. bump,
specular, normal maps.
Let me know what you know and limitations your aware of.
Thinking about learning/playing with normal and specular maps, but thinking
probably only bumps are going to be supported for now...
Wishful thinking, some fun ideas in mind. =)
Katie
