Hi all,
UPDATE: Working Script at the bottom ....
My goal is to make a script which deletes small objects from a sczene.
I managed to copy paste myself a script from PerAnders wonderfull Wiki (http://www.per-anders.net/w/index.php). I guess I am stuck at the point how to get the min value and compare it hence i get tripple values (vector i guess).
the output is e.g.
[260.1234456,90.123456,45.123456]
how do i compeare this with a value ?
i marked the problem zone down in the code
thanks for your help in advance.
here is the script so far
getNextObject(op)
{
if (!op) return null;
if (op->GetDown()) return op->GetDown();
while (!op->GetNext() && op->GetUp()) op = op->GetUp();
return op->GetNext();
}
//Class for finding the bounding box of a set of points
class MinMax
{
var min;
var max;
public:
Init();
AddPoint(p);
GetMin();
GetMax();
GetMp();
GetRad();
GetSize();
}
MinMax::Init()
{
min = vector(MAXREAL);
max = vector(MINREAL);

{
if (p.x < min.x) min.x = p.x;
if (p.x > max.x) max.x = p.x;
if (p.y < min.y) min.y = p.y;
if (p.y > max.y) max.y = p.y;
if (p.z < min.z) min.z = p.z;
