Kangaroo2 LineLine Goal


#1

Hi,

I am working with lineline collision on Kangaroo2 implementing RTrees and Spatial Grid for faster collision detection.

All the particles and goals are initialized in a clean manner by indexes, therefore I am using this LineLine Goal constructor:

public LineLineCollision(int a, int b, int c, int d, double r, double k, bool _show)
{
    Strength = k;

    PIndex = new int[] { a,b,c,d };
    Move = new Vector3d[4];
    Weighting = new double[4] { k, k, k, k };

    R1 = R2 = r;
    show = _show; //Preview output
}

Each frame I delete last collision goals and add new ones.

The question I have:
How to write a Line Line Goal for calculating all pairs of lines in one goal?
I am wondering how to sum up all the move vector as it should be similar thing to points collision.

Instead of constructor:
public LineLineCollision(int a, int b, int c, int d, double r, double k, bool _show)
I want to have a constructor (orginally I have the different constructor but this represent the idea)
public LineLineCollision(int[] a, int[] b, int[] c, int[] d, double r, double k, bool _show)

Kind Regards,
Petras Vestartas
