Titanic in 3D has already made 400 million yuan in the Chinese box office. And today we look at the cutting-edge technology that's at work behind the scenes to bring a classic movie into the digital age. Tears and tissues at the ready.

The key to a good movie is always a touching story. But now with 3D technology, the story-telling is enhanced in every way. That's why it has rekindled the many people's passion for this classic.

A movie goer said, "I was quite young the last time I saw it, I think it would be a whole new experience."

But injecting 3D life into an old movie is no easy task - it took over 300 technicians 6 months to complete the conversion at the expense of 18 million US dollars. And it wasn't just technical labour, but a lot of creativity too.

Prof. Sun Lijun, Beijing Film Academy, said, "The technicians simulate the difference between the left and right eyes with two cameras - using this difference they are able to create an optical illusion, bringing depth to the pictures. But it's a delicate and demanding process. A technician and a film artist have to work together on each scene to ensure the final product is comfortable and smooth in the eyes of the audience."

Demanding as it may be, the reward is tremendous. Released on the 100th anniversary of the sinking of the Titanic, the 3D movie has been successfully revived, grossing over 20 billion US dollars world-wide in less than 12 days of it release. The movie is certainly not sinking.

三维电影（3-D film），是使用一种立体镜视觉显示系统，再制画面将左右眼平面投影影像立体显现成像，令观众对影像产生立体深度。技术上，通常采用两台摄影机摆设，同步拍摄影像，取得主体左右侧体的立体感。观看时，观众的视觉皮层会自动对图像结合为单一三维影像画面。现代电脑技术已能够不采用传统双机"拍摄"，使用CGI电脑特效制作三维电影。欣赏时需要配戴合适的立体眼镜。

在影院看的是立体版本的IMAX技术。为营造出立体景深，IMAX 三维采用了双摄影机及双投映机拍摄及放映。

目前IMAX 三维放映时采用偏光式放映，观看时以配戴偏光眼镜来分析立体影像。
