I haven't done picking but quoting from page 259 of 'The Java 3D API
Specification' latest edition:
"Java 3D includes helping functions that aid in intersecting various
geometric objects with objects in the virtual universe by intersecting an
oriented ray with all the objects in the virtual universe. That function can
return the first object intersected along the ray, all the objects that
intersect that ray, or a list of all the objects along that ray sorted by
distance from the ray's origin"
Dont know if this help but good luck.
