List of locatenear() Examples

Examples of locatenear()

com.nr.cg.KDtree.locatenear()
com.nr.cg.Nearpoints.locatenear()
Once the tree is constructed, this function can be called repeatedly with varying points pt and radii r. It returns n, the number of stored points within radius r of pt (but no larger than nmax), and copies those points into list[0..n-1]. @param pt @param r @param list @param nmax @return

Examples of com.nr.cg.KDtree.locatenear()

    Point[] qolist=new Point[M];


    testpt.x[0]=0.6;
    testpt.x[1]=0.7;
    r=0.1;
    nkd=kd.locatenear(testpt,r,kdlist,M);
    nqo=qo.locatenear(testpt,r,qolist,M);


    // See if KDtree and Nearpoints found the same number of
    // neighbors withing radius r
    localflag = (nkd != nqo);
