This is probably something basic, but i am not smart enough to figure out how this is done.

i have a model, and i need to make one (if that cant be done, ill settle with 3 variables xyz) variable that contains the position of every vertex in the model.
i know you i have to use loops to figure this out but for some reason every time i tackle this it confuses the hell out of me and i am left with a headache.

Very confusing consept

i am new to vertexdata, just started playing with this today

just to avoid being flamed, most of whatever i learned about vertex data came from the search function of this forum.

Well, I'm new to modeling to, but it seems to me that the object itself contains all that data. You can use it with VERTEX DATA commands.

If you MUST have it in a separate variable, try a user created type like this:

Look in The GameCreators newsletter, issue 41, for a tutorial on vertex data commands.

I hope this helps cure the headche.


Whatever...

You can do it in one variable - a (3*n) float or (n) vector3d array. You'll need to make your own UDT for a vector.

The absolute best way to do this is to use a memblock, which stores 12 bytes for each position.
