# Ray intersection distances returning Infinity

I have a slight problem whereby any of my collisions are returning Infinity as the distance between the Ray origin and the Geom in question. See code extract below:

``` results = new TrianglePickResults(); results.setCheckDistance(true); ... ArrayList<Spatial> children = objectNode.getChildren(); SpaceObject collidedObject = null; SpaceObject spaceObject; Laser laser; Node node; float distanceTravelled; float distance; float min = Float.MAX_VALUE; if(children != null) {    for(int i=0; i<children.size(); i++) {       if(children.get(i) instanceof Laser) {          laser = (Laser) children.get(i);          laser.getRay().getDirection().set(laser.getLocalTranslation());          laser.getRay().getDirection().subtractLocal(laser.getRay().getOrigin());          laser.getRay().getDirection().normalizeLocal();          distanceTravelled = FastMath.abs(laser.getRay().getOrigin().distance(laser.getRay().getDirection()));          for(int j=0; j<objectCollection.size(); j++) {             if(objectCollection.get(j) instanceof Vessel) {                spaceObject = objectCollection.get(j);                results.clear();                node = (Node) spaceObject.getSpatial();                node.findPick(laser.getRay(), results);                for(int k=0; k<results.getNumber(); k++) {                   distance = results.getPickData(k).getDistance(); System.out.println("Checking laser agains SO: "+spaceObject.getSpatial().getName() + " - Distance: " + distance);                }             }          }                    laser.getRay().setOrigin(laser.getLocalTranslation());       }    } } ```

The result is always: Checking laser agains SO: Model - Distance: Infinity
What would cause this?

Thats exactly what I thought. I tracked it down to a class I've forgotten and it was due to an empty array of Tri's - if that helps anybody

Infinity should mean it didn't intersect the object?

whatever it is, maybe i've found it as well:

in some cases, i found 0.0 and infinity in my pickresults. if either of these values means "no contact", then there shouldn't be a pickresulst at all.
