*Eyes bug out*

I think I'll take a few more classes and read some more books before I even try to understand that :p

Actually, I've never dealt with graphics or anything visual outside of beyond so I think I should tackle 2D C++ programming before I move to 3D.

It does look a little complicated at first, but when you do all the math it works out. =)

Oh, you have no idea how much it makes my head hurt, I feel like a newbie again!

If you really want to be freaked out by code, try looking through the source for POV-Ray sometime. My first foray into customizing that worked with height field code very similar to what Goten84 showed, only much more complex. (I didn't have to write it; I only wrote in some routines to change the way triangle smoothing was done.)

The code isn't THAT hard, I bet If I wanted to, I could skim through my OpenGL docs and figure this one out soon :) If you know what all the command mean, you wouldn't have that many problems reading the code :)

Yep, at first structs and pointers look kind of scary but they're no big deal once you work with them a little bit. I'd imagine the same thing would happen with this code, although it is a little more complicated than the concept of structs and pointers :p

The scariest things in languages are when new operators get thrown in. When a new function is added, it's usually no problem, just look it up and see what it does. I've never used the : operator in C++ yet so that adds to my confusion :p The most advanced operator I've used is the -> operator. Isn't -> used to access a variable in a struct from the pointer to the struct? Basically, tree -> num_apples would replace (*tree).num_apples

Wait a minute...that doesn't look right, now I'm confusing myself :p

You sure? I'm pretty sure they're different. You use them to get the same result but I think the -> is a shortcut when your using pointers to structs. I forgot that was in C, ehgahd, I only know four languages (well ok, HTML isn't a real language, too bad :p) and I'm getting them mixed up already. I think I'll hold off on trying to learn anymore.

@_@.
If that were VB I could probably figure it out one way or another.

My favorite 3d Engine for VB is TrueVision, but I`m afraid I`m kinda a newbie at vb too, so I couldnt do much

Sorry about that....

I started C++ when I was a sophmore in school, now I'm like going to college and I've been programming in C++ for a years now. Sometimes it seems like I'll never know enough, there's just so much C++ can do you'd be amazed.

Going to college since now these days people are looking for degrees. ;)
