Mars stereo images on your PC – without the glasses! Here are two known methods of producing a 3D illusion on any PC monitor without using glasses. Both methods utilise two separate images and the processing power of your brain to create a 3D depth effect. 1) Cross eyed Using the diagram below, open an image viewer (such as Corel PhotoPaint, or even just two separate internet browsers) and arrange the two separate images available from NASA as shown – PIA04992 on the left and PIA04991 on the right. Ensure they are both the same scale and select an appropriate section of the image such that both sides show roughly the same image. With your right eye look at the left image and with your vice-versa with your left eye. In other words, go cross-eyed!# It helps to use card or your hands (shown) so that each eye can see only one image. You should be approximately 30-60cm from the screen for best results. Hopefully you will see the section of the image you have chosen in 3D! For your own comfort, we suggest viewing for only a few seconds at a time.#
2) Animated
Motion Illusion By rapidly switching left and right images, the brain perceives depth by determining how far an object moves between frames. The greater the displacement, the closer the object is likely to be, in a generally static environment.
