3D is becoming popular nowadays, it is everywhere in our daily life, no matter in a movie like Avatar, or 3D games, PSP or Samsung 3D TV at CES. Not even say in the commonly used car GPS. So what is 3D and why does your car GPS need the newest 3D view map feature? Now I would like to introduce you to this new technology and give you kind advice to follow.

3D computer graphics (as opposed to 2D computer graphics) are graphics that use a three-dimensional representation of geometric (often Cartesian) data that is stored in the computer for the purpose of performing calculations and generating 2D images. Said images can be for later visualization or for visualization in real time.

You can see how the Avatar movie is so much in fashion all over the world as it is a fully 3D movie. 3D is a movie that enhances the illusion of depth perception. Derived from stereoscopic photography, a special motion picture camera is used to record images viewed from two perspectives (or computer-generated images generate both perspectives), and special projection hardware and/or glasses are used to provide the illusion of depth when watching the movie.

The Global Positioning System (GPS) is a navigation technology that provides precise time and location data through the use of 24 Navigation Satellite Timing and Ranging (Navstar) satellites. Each satellite completes one orbit around the Earth every 12 hours. They are positioned at an altitude that allows them to cover the same ground once every 24 hours (minus four minutes).

Car GPS is one of our necessary in-vehicle tools, but why does your GPS need a new 3D view?

1. You can see a more vivid map and watch videos like in the cinema even when you are driving in the car when you use a 3D view GPS. It will be a very pleasant browsing experience for you.

2. The 3D view represents one of the most important features of the new technology. Therefore, your GPS does not need to be updated in the future at least 5 years.

3. Together with the built-in legal map, you can get more accurate location information and better understanding. Like Eonon GPS DVD, it has a built-in map of Europe, USA or Australia.

4. You can also choose to view your map in 2D view. It is your choice when you want to make a small change at some point.

So when choosing a great top GPS for your beloved car, don’t forget to take this 3D feature into account!
