Even though 3-D images have grown popular in Japan's film and game industries, they remain a rarity in classrooms.

But the International School of the Sacred Heart in Shibuya Ward, Tokyo, has embraced the concept of using three-dimensional teaching materials and started using such images in its science classes in April. "We're the first international school in Australasia to have teaching materials using 3-D software," said Mary Hisaoka, the school's admissions and development coordinator.

The total cost of buying the 3-D software from U.K.-based Amazing Interactives, as well as 3-D glasses to view the images, was covered by donations from parents, said Hisaoka.
