From source file:BoundsTest.java

protected Group createPoints() {
    Group group = new Group();

    final double kRadius = 10.0;
    Point3d points[] = new Point3d[kNumPoints];

    for (int n = 0; n < kNumPoints; n++) {
        double randX = (java.lang.Math.random() * kRadius) - kRadius / 2;
        double randY = (java.lang.Math.random() * kRadius) - kRadius / 2;
        double randZ = (java.lang.Math.random() * kRadius) - kRadius / 2;

        points[n] = new Point3d(randX, randY, randZ);
