Disney's:
Alice in Wonderland, Snow White, Sleeping Beauty, Dumbo, Donald Duck's Birthday Celebration, Romance
Bambi, Fantasia and Peter Pan (none of them seem to be 3D)
Europe and America are also good:
Madagascar 1, Kung Fu Panda, Shark Story and Egyptian Prince (the last one is not 3D)
In fact, you can read all Miyazaki Hayao's works. But it's not 3D, but it's beautiful. For example, My Neighbor Totoro Spirited Away's "The Gratitude of Cats" and so on.
