    Hi,

    I am trying to get the position of a some points between two points. this is how I try to do it, but it doesn't work. somehow the direction is totally weird, as soon as p1Offset and p2Offset are changing:

      
    SplineObject* tempSpline = SplineObject::Alloc(pointCount,SPLINETYPE_LINEAR);
    Vector* tempPoints = tempSpline->GetPointW();
      
    for (int i=0;i<pointCount;i++)
    {
    Matrix dir= HPBToMatrix(VectorToHPB(p2-p1),ROTATIONORDER_DEFAULT);
    Vector perStep = (p2 - Vector(0,p2Offset,0) * dir - p1 + Vector(0,p1Offset,0) * dir) / pointCount;
    tempPoints[i] = p1 + Vector(0,p1offset,0) * dir + (i + 0.5) * perStep;
    }
    

    the simple distribution of the points between p1 and p2 work with no problem while p1Offset and p2Offset are zero. what i want to do is to be able to set a distance from p1 / p2 so the points distribute between those two offseted points.

    i am quite sure it has something to do with how i calculate the direction

    would be cool, if someone could have a look and tell me what I am doing wrong.

    cheers,
    Ello

    ah, got it. i needed to place the offset to the z and not the y component of the vectors...
