# Difference Between 2D vs 3D and 4D Shapes Animations

This dimensional tutorial will clear your mind about the difference between 2D vs. 3D and 4D. Before going further into the topic, it is essential to first learn about “dimension”. 1D, 2D vs. 3D and 4D. These all are dimensions technologies. Here 1D stands for (1 Dimension), 2D (2 Dimension), 3D (3 Dimension) and 4D (4 Dimension). A dimension is a measurable extent of a physical quantity, such as length, breadth, depth, or height.” For example, 5-metre length, 3-metre width or 10 feet height are all dimensions. The terms 1D, 2D and 3D are also called one-dimensional, two-dimensional and three-dimensional respectively. They are named so due to the number of dimensions draw.

## Difference Between 2D 3D and 4D

### 1D

____________________________________________________________

The above-drawn line is one dimensional or 1D because it shows only the length.

## 2D

• An object which has only two dimensions, i.e. length and height, is called two-dimensional space or 2D.
• 2D objects do not possess depth.
• 2D shapes are flat and do not acquire essence of solids.
• Examples: squares, rectangles, circles.
• In a mathematical expression, it is written as x-axis and y-axis.
• The movies and videos are usually recorded in 2D.
• Many creatures, such as ants, have only two-dimensional 2D They lack sense of depth.

## 3D

• An object which possesses three dimensions, such as length, height and depth, is called three-dimensional object or 3D.
• Examples: humans, ball, mobile, laptop and various other physical objects.
• In a mathematical expression, it is written as x-axis, y-axis and z-axis.
• The geometrical objects in this category are cubes, cylinders, etc.

### 3D Applications

1. 3D modelling
• To put it simply, 3D modelling is a process to build a three-dimensional object by using any specific software.
• For example, a company want to manufacture a new product and is likely to make a prototype or sample design. To accomplish this task, designers in the company may use software, such as Solid Works, Auto CAD, to design and build a graphical and virtual model of their product.
• It improves efficiency and saves time as any error can be corrected during designing.
• It is an economical method and provides manufacturers with the great flexibility to get desired.
1. ###### 3D Printing
• 3D printing refers to a process in which a computer program is used to build a solidified 3D object.
• It involves additive manufacturing, a process in which the designed object is built by laying down successive layers of the solid material.
• Various complex designs can be turned into reality through 3D printing.
• Designers can send the design to another designer and the object could be produced easily.
• The development of design through additive manufacturing saves money.
• It mitigates the risk of waste of investment if the design is not compatible. Otherwise, the money would have been spent on the real
• If the design does not work, the company can easily replace it with another one without compromising on any considerable thing.
1. 3D Film
• In simple words, it is a motion picture or video, recorded in such a way that it increases depth perception of viewers.
• The working principle behind this concept is a stereoscopic
• Human mind combines both images from our eyes and creates a 3-dimensional vision.
• The filmmakers use this technique and place two camera lenses side by side and a 3D movie is recorded.
• A viewer has real-time experience.
• It increases the quality of the video.

## 4D

• While 3D indicates length, height and depth, the 4D adds another dimension called time or space-time.
• The idea of time as 4th dimension was given by Albert Einstein in his famous Theory of General Relativity 1905.
• There is a prevailing debate whether the time is really 4th dimension or not.
• 4D is also attributed to consciousness and mind power.
• 4D is represented by tesseract, also described as 4D analogous of the cube.
• Unfortunately, humans can not see 4th dimension as they lack this ability, just like some creatures cannot see 3rd dimension i.e. depth.
