hmm. still getting some pretty funky results.. could it be because I am looping through all of the points and effecting each individual point? is it possible to compare the result of a variable in one cycle of a loop to the result in the last cycle of a loop?

I assume I'll need a global variable for that.. do you think it would be more effective to catch the location of the last point that was modified in the global variable and use that to adjust the position of the next point. make the mix function mix the distance between the last point and the current point?
something like that?

you could try to use some smaller value for the noise functions. for example point _/100.. and see what happens. i'd use a slider for this value than, too...

ha, you are just too fast for my replies. however, i wouldnt care for that.. you have your base form and apply just some values to each point, so the form still stays similar to your original mesh. maybe you dont use a cube as a base, but a sphere with low polycount? maybe you apply some scale vector additionally so the object doesnt look so round anymore

well smaller numbers definitely help but still don't quite give me what I'm looking for. I think I might need to compare the current point position with the last point position.. Maybe.,. LOL

if you use Mix with keeping more to your original point, say values between 0.5 and 1 for t, you should be able to get exactly that (in theory of course, since i'm not actually trying atm)

LOL.. yep you're right... it worked/./ just had to do a little tweaking with the numbers.. Thanks a lot for your help ello. I really appreciate you taking the time to help me.

Hey while you're here do you know if it is safe to subdivide an object from within the GetVirtualObjects() method?

i place my object inside a hypernurbs (Osds) to do so, but i think you mean something other. it should be able by using CommandData
here is a snippet of how i used the optimize command on a polygon object.
if (op->GetType()==Opolygon)
{
ModelingCommandData cd;
cd.doc = doc;
cd.op = op;
BaseContainer bc;
bc.SetReal(MDATA_OPTIMIZE_TOLERANCE, tolerance);
bc.SetReal(MDATA_OPTIMIZE_POINTS, TRUE);
bc.SetReal(MDATA_OPTIMIZE_POLYGONS, TRUE);
bc.SetReal(MDATA_OPTIMIZE_UNUSEDPOINTS, TRUE);
cd.bc = &bc;
if(SendModelingCommand(MCOMMAND_OPTIMIZE, cd))
{
cd.op->Message(MSG_UPDATE, NULL);
BaseTag *phongTag = op->MakeTag(Tphong);
BaseContainer *bc = phongTag->GetDataInstance();
bc->SetBool(PHONGTAG_PHONG_ANGLELIMIT,TRUE);
bc->SetReal(PHONGTAG_PHONG_ANGLE,ToRad(winkel));
} else {
GePrint("failed");
}
}
hope this makes sense
edit: in your case it'd be the MCOMMAND_SUBDIVIDE .. check the sdk for its parameters...
