真唯立体银幕(reald),通过有规律地分配左右眼视觉频率,使观众看到立体影像(大意)
RealD however uses a single projector that alternately projects the right-eye frame and left-eye frame, and circularly polarizes these frames, clockwise for the right-eye and counterclockwise for the left-eye, using a liquid-crystal screen placed in front of the projector lens. Circularly polarized glasses make sure each eye sees only "its own" picture, even if the head is tilted. The very high framerate, which is 72 frames per second per eye, makes sure the image looks continuous. In RealD Cinema, each frame is projected three times to reduce flicker, as the source video is usually 24 frames per second. The result is a seamless 3-D picture that seems to extend behind and in front of the screen itself.
目前Journey to the Center of the Earth 3D 就是利用了这种技术的电影

目前北美有近3000块“Real D”3D立体银幕(可我在网络查不到这种银幕的真实照片),估计“天神下凡”应该是用这种银幕播放的了!
