Connect all Objects with Spline

[rustEdge]

This question's been popping up fairly often...

Anyways, here's the code that'll handle child objects. Paste the script into a COFFEE tag attached to a Spline Object and it should work.


main(doc,op)
{
var i, j, k, pointcount;

i = 0;
var a = op->GetDown();//count number of children
while(a != NULL){
a = a->GetNext();
i++;
}
//allocate array for coordinates
pointcount = i;
var pointadr = new(array, pointcount);

a = op->GetDown();
pointadr[0] = a->GetPosition();
for(i = 1; i<pointcount; i++){//get coordinates of children
a = a->GetNext();
pointadr[i] = a->GetPosition();
}

k = 0;//count number of splines needed
for(i = 0; i<pointcount-1; i++){
for(j = i; j<pointcount-1; j++){
k++;
}
}
var vc = new(VariableChanged);

vc->Init(pointcount, k*2);//allocate points
op->Message(MSG_POINTS_CHANGED, vc);

vc->Init(op->GetSegmentCount(), k);//allocate segments
op->Message(MSG_SEGMENTS_CHANGED, vc);
print(k," ");

var gg = op->GetSegmentCount();
print(gg, " ");

var segmentcount = new(array, k);
for(i = 0; i < k; i++){
segmentcount[i] = 2;
}
print(segmentcount[3], " ");
print(op->SetSegments(segmentcount), " ");//assign 2 points per segment
println(op->GetSegmentCount());
k = 0;// generate point pairs
for(i = 0; i < pointcount; i++){
for(j = i; j < pointcount-1; j++){
op->SetPoint(k, pointadr[i]);
k++;
op->SetPoint(k, pointadr[j+1]);
k++;
}
}

op->Message(MSG_UPDATE);
}


Here's a scene file (http://www.genemagtoto.com/c4d/uberatom.c4d) that shows how it works.

I guess this can be further developed into a generator object much like the Mograph Tracer. Unfortunately I don't have the time do make it, as I'm working on a few plugins at the moment.


Cheers!

Thank you very much. This is exactly what i was looking for.
Is there a simple way to make it work with thinking Particles? That would be great.

Thanks for your help.

It is doable, unfortunately I still haven't touched particles with COFFEE or C++. I am trying to develop this into a true "Tracer Object" variant, but so far I'm only at the point where I can only use the coordinates of the objects in a List parameter. I've yet to implement using points from polygon and spline objects, and particles.
