3D THE WAY OF OUR VISION

1. 3DTHE WAY OF OUR VISION YASHODHAR SATYAMITRA

2. We have 2 eyes which act as 2 cameras. These capture 2 separate images from 2 different perspectives. • Our brain uses these 2 images to calculate the distance of the object from us. • Here we are going to elevate this concept by using 2 cameras

4. HERE WE ARE GOING TO CALCULATE THEZ CO-ORDINATE

5. Formulae:

6. How 3D is implemented with goggles • The goggles are made such that different images are shown to different eyes • There are many type of goggles • Red cyan glasses • Polarized glasses • Active shutter glasses

7. Red cyan glasses •  A red filter lens over the left eye allows graduations of red to cyan from within the anaglyph to be perceived as graduations of bright to dark. The cyan (blue/green) filter over the right eye conversely allows graduations of cyan to red from within the anaglyph to be perceived as graduations of bright to dark.

8. Polarized glasses •  Polarized glasses restricts the light that reaches each eye thus showing different images to each eye. • Advantages : • Generally inexpensive • Do not require power

9. Active shutter glasses • It works by openly presenting the image intended for the left eye while blocking the right eye's view, then presenting the right-eye image while blocking the left eye, and repeating this so rapidly that the interruptions do not interfere with the perceived fusion of the two images into a single 3D image. • Advantages : • They mostly eliminate 3d cross talk • They are colour neutral, enabling 3d viewing in the full colour spectrum
