what's interpolation?

This is a discussion on what's interpolation? within the Game Programming forums, part of the General Programming Boards category; what's interpolation? (i'm a sophomore in high school, and they haven't really taught us yet, Accelerated Algebra II)...

    The gist of the term is to insert something into something else; to insert estimated values or to determine an outcome by inserting estimated values into a function.

    Usually interpolation refers to determining an outcome that you don't really have enough information to determine.

    You're confusing interpolation with extrapolation.

    Interpolation is actually a pretty general term. Basically, it means that you are finding an intermediate result, for instance, interpolating a rotation over time means that based on time, you will be a different stage during the rotation.

    ook, well, do you think you could help me with this? at the bottom is what I'm trying to figure out, (i don't want to repost it, because I don't think the format'll stay the same...)

    Yup.

    If it's just a square, then why are you using a strip of 4 triangles in the first place!? All you need is a strip of 2 (or a fan of 2).

    Anyways, if you really want 4 triangles (for some odd reason), the location of the center would just be the point defined by a corner plus the vector defined by the opposing corner minus the original corner divided by 2.


    Example

    12
    34

    Point1 + (Point4 - Point1) / 2

    the reason i'm using 4 is because with two, if i make the diagonal of the two go from bottom left to top right, then whenever i raise the vertices in the top right or bottom left, they raise the plane all the way across, and I want it to just change one half

    that's REALLY cool that you go to digipen, that's where i'm planning on goin' after MIT, i read about it in EGM, lol, so is it as hard as I've heard? i've been trying to get ready for DigiPen since my freshman year (high school) I've made quite a few games so far, actually, which (i think) is pretty good for only having known openGL since november, 2002, lol.

    I'm also going to a National Youth Leadership Forum on Technology this summer, so that should help me get in there a bit easier (and i got a scholarship to the NYLF on Tech thing, too)

    You may want to re-think your gameplan. MIT is a great school. The first two years ( maybe 3 ) would probably be boring to you depending on how much graphics programming you do. Also, they have REALLY dumbed down the program a lot due to whatever reasons. They definitely don't teach as much as they used to in certain classes it seems. Definitely get a lot of opinions before you go because it is quite expensive. PM me if you have more questions and I can probably answer most/all.
