double d =Math.sqrt((x1-x2)*(x1-x2) + (y1-y2)*(y1-y2) + (z1-z2)*(z1-2)); You can also do (where p1 and p2 are Point3d) p1.set(x1,y1,z1); p2.set(x2,y2,z2); double d = p1.distance(p2); BTW, I'm afraid you will have to check some 3d geometry books anyway if you want to play with 3d graphics. When you will start to work with matrices/quaterions it will be not so easy.
