How secure is your password ?
Now with the changing technology , fast processors and many tools on the Internet, cracking password has become a Child's Play

SETTING 3D PASSWORD !!
The 3D password presents a virtual environment containing various virtual objects
The user walks through the environment and interacts with the objects using navigators
The password is a combination and sequence of user interactions that occur in the 3D environment

Θ All of us think of a printer as something that can print out documents, create informative newsletters etc. Although these are still the main functions of printing, there's also a new trend taking hold in the world of printing that does not involve only ink: 3D printing.
Θ This type of printing actually uses a larger printer, filled with a compound, to create 3D objects from blueprints created on-screen.

1. Holography (from the Greek, whole + write) is the science of producing holograms invented by Dennis Gabor
2. It is an advanced form of photography that allows an image to be recorded in three dimensions
3. The technique of holography can also be used to optically store, retrieve, and process information

I. AUTHENTICATION : Hologram stickers cannot be scanned or photocopied so they are used in authentication of passports ,books etc.
II. ATTRACTIVE : Hologram stickers can also used in packing as they create a unique and attractive complement to existing packaging

3-D GLASSES
![Page 22: 3-D TECHNOLOGY](https://reader036.vdocument.in/reader036/viewer/2022062418/554a1b02b4c90507558b5586/html5/thumbnails/22.jpg)
Working of Binocular Vision
Binocular vision is dependable on the distance between our eyes
Each eye sees the image at a slightly different angle
22
![Page 23: 3-D TECHNOLOGY](https://reader036.vdocument.in/reader036/viewer/2022062418/554a1b02b4c90507558b5586/html5/thumbnails/23.jpg)
The brain takes the information from each eye and combines them into one image
Difference of angles makes image have depth
23
![Page 24: 3-D TECHNOLOGY](https://reader036.vdocument.in/reader036/viewer/2022062418/554a1b02b4c90507558b5586/html5/thumbnails/24.jpg)
Types Of 3D Glasses :
Anaglyph
Pulfrich
Polarized

![Page 25: 3-D TECHNOLOGY](https://reader036.vdocument.in/reader036/viewer/2022062418/554a1b02b4c90507558b5586/html5/thumbnails/25.jpg)
Working of Anaglyph Glasses
On the screen ,two images one blue and one red is displayed
The lenses only let one image into each eye
25
![Page 26: 3-D TECHNOLOGY](https://reader036.vdocument.in/reader036/viewer/2022062418/554a1b02b4c90507558b5586/html5/thumbnails/26.jpg)
Working of polarized glasses
Polarized lenses are both a gray color and let color through
The lenses are specially cut at opposing 45 degrees
Two images are projected on the screen and each one has a different polarization
26
![Page 27: 3-D TECHNOLOGY](https://reader036.vdocument.in/reader036/viewer/2022062418/554a1b02b4c90507558b5586/html5/thumbnails/27.jpg)
The polarized glasses allow only one of the images into each eye because each lens has a different polarization. 27
![Page 28: 3-D TECHNOLOGY](https://reader036.vdocument.in/reader036/viewer/2022062418/554a1b02b4c90507558b5586/html5/thumbnails/28.jpg)
Working of pulfrich glasses
These glasses use the concept of one dark and one light lens to form 3D images
The image through the dark lens reaches the brain slightly after the image that went through the clear lens, creating a 3D illusion

CONCLUSION AND FUTURE SCOPE
1)3-D Password setting is a very useful technology for the areas where high security risk is involved
2)3-D tattoos and street art has capacity to capture the market of advertisement industry
3)3-D printing has a great future scope for example NASA engineers are printing 3-D printing parts, which are structurally stronger and more reliable than conventionally crafted parts, for its space launch system. Use in medicine: jaw transplant , to grow new human tissue with the help of bio printer
