CHAPTER-1

WHAT IS 3D? WHAT IS NOT 3D??

Hi friends, this is our 1st chapter in 3D. This chapter contains a basic theoretical view of 3D which is necessary before getting into this world, it does not involve any practical work in sophisticated software....the topic that we are going to discuss in this session are

• What is True 3D ?
• Difference between 2D and 3D

Lets get started...............

WHAT IS TRUE 3D??

In technical terms 3D is known as stereoscopic vision (illusion of depth) ...... to put this in a simpler form , -3D is any cartoon series or a cartoon movie which has 1 essential factor - Depth- in all its character and backgrounds (layouts) .... lets look at  a small example to make this much more clear .... place a cube in front of you and view it ... now turn the same cube a little in the clockwise or anticlockwise direction

Cube - front of you

Cube- turned in anti-clock wise
direction

  we can clearly see the difference between the two position of the cube. The front position just shows you the flat view of the cube you cant see the  thickness of it,but in the side turned position you can see the thickness - which is the depth - which makes the cube looks more realistic.

From my own experience from my dad i realized when we mention something about 3D they often misunderstands it as polarized 3D glasses (the glasses that are given in theaters in 3D movies). But we have to be clear that it is just a type of viewing system - polarized 3D viewing system - but this is not the only 3D ... for example once i designed a 3D model and showed it to my dad and my brother .... my dad asked whether he has to view it with those 3D glasses and my brother was also arguing with me that only the movies that we are seeing in theaters with the 3D glasses are true 3D and if we see the same movie in our laptop or television without those glasses is not true 3D .... so please understand that when you see Avatar movie in theaters it is 3D and when you see the same in your laptop or TV that is also True 3D.....its just that in theaters they are using a different viewing system ( if u want to know know more about this polarized 3D viewing system let me know i will write a separate blog about it)

DIFFERENCE BETWEEN 2D AND 3D

Now moving on to our next topic ..... difference between 2D and 3D the reason i added this topic is because of my first 3D class in my college....in our class our sir asked us one basic question how will  you identify a 3D cartoon from a 2D cartoon .... half of the class was in a confusion and the other half of the class was giving too technical answers...

                                                    Lets see the technical part later.... now i will give you a simple example to remember the difference between 2D and 3D ...... Example- If you draw a teddy bear or a bike in a drawing sheet that's 2D and if you make a clay model of the teddy bear or the bike that's 3D....and the difference is simple the clay model will give the depth to the teddy bear making it a True 3D object which we saw under the previous heading 

                                                Moving to the technical part 2D is based on the Cartesian co-ordinates which has only X and  Y axis where as in 3D we have a additional  Z-axis to the Cartesian co-ordinates which gives the Depth with a center (0,0,0) known as center of the global space or world space

 Cartesian co-ordinates
2D

3D - with Z-axis

Now lets see the difference where its really required-in cartoons and movies-lets identify which is 3D and which is 2D in the below cartoons

                   

         Tom and jerry my favorite cartoon since my childhood times ..... its 2D cartoon where as Tangled my latest favorite animated movie is 3D

Nobody can forget the man with the spinach - Popeye the sailor man....the right side image is from the original Popeye series which is 2D whereas the same Popeye show was created in 3D now due to its popularity which is in the left side 

Hope you have enjoyed my 1st blog and also understood the basics of  the 3D world.....To check your understanding i have a small test for you below please try to do it.... we will have these kind of test after each chapter

Questions

1. Identify five 2D and 3D animated movie or cartoon series and 2 cartoon series or movies which was 2D in the beginning and was later converted to 3D like Popeye
2. Identify which side is 2D and which is 3D in the below images with the name of the cartoon series or movies

 

okay guys tats it for chapter one we might have one more theory chapter about 3D PIPELINE after which we can get into the software and start to have some fun!!!....if you have any doubts or clarifications or suggestions about my blogs feel free to mail me ... my id is mangal1105@gmail.com.....you can send your answers to the above question also to my mail....
