Can someone explain in details the difference between 2-d and 3-d ??

Answer 1

In addition to everyone else, to illistrate the difference between 2-d and 3-d. If you look at a wall, and forget about it having a fixed width, you currently see only 2 dimensions, a length, and a height.

For a 3-d object, have a look at an opened door, this door has the 2 dimension from before, a length, and a height. It also has a 3rd dimension being the width.

In drawing, a 2-d wall

Answer 2

A 2D Object is a 2 dimensional object that is flat (Only has legnth and height)

A 3D Object is a 3 dimensional object that takes this further and adds depth to the picture to make it appear like a real object would (Legnth X Height X Depth) Almost everything now is in 3D

Answer 3

2 dimensions and three dimensions are different only because 3d has one extra dimension: the depth dimension.

2d has height and length, but 3d goes deep and provides a perspective that creates a unique view when looked at from different angles. It allows physical objects to be represented in their entirety, and not simply an outline, silohuette, or other type of abstract image.

Answer 4

d stands for dimension. 2d means something that got only height and width, it can be placed in a plane. 3d is something that got, height, width and depth, and you cant place it in plane, but you need space.
simple example is old mario brothers is a 2d game, while the wolf3d is a 3d game. In mario you can make mario move only in two dimension. But in wolf 3d you can make the character move anywhere.

Answer 5

2-d = height and width

3-d= heigh, width, and depth

d=dimension
