Difference between 2D and 3D
You might have heard the term “animation” and the technical definition is the picturing of the sequence of positions to create an illusion of motion. With the advent of computers, animation evolved from hand drawings to perhaps the most recognized forms of computer 2D animations and 3D computer animation.
While the entertainment industry extends to create astonishing and impressive computer generated 3D animations, what used to take a great deal of manpower, not to mention pencils, cells, etc. can now be accomplished by a single individual.
2D Drawings & Animation:
The most familiar form of 2D animations can be found by watching Saturday morning cartoons with your kids, or even simpler animations every day when you surf the web. It takes on the forms of advertisements, e-cards, etc.
The basic starting point for all animations is a storyboard that lays out the basic script in a visual format, much like an extra large comic strip.
From there a rough audio track of the script is created to give artisans something to sync with their drawings. This form of animation involves “vector graphics,” which means that the images are arranged upon mathematical equations, rather than by an array of pixels, such as in “raster graphics.”
3D Drawings & Animation:
Alike 2D animations, 3D computer animation technique has a distinct process, as an episode being done in 3D is created long before any realistic animation begins. Even in simple terms, most people automatically consider 3D when they are speaking or reading about computer animation, partly due to its flexibility or springiness.
What is that people do not realize is the entertainment industry, only account for a fraction of the 3D animations market?
Actually, there is a minute difference between computer animation and what is called traditional animation.
The basic difference is the tools that are used to create animations, the effort, and the price. The traditional 3D animation was more like acclamations and was done by using stop-motion cinematography techniques. Substantially, the right concept of 3D animations did not really catch on, until the use of computers for animation became more cost-efficient and practical.
Benefits of CAD 3D drawings over 2D:
- Storage and accessibility: CAD files can be stored on a computer or archived in any storage media. The software can also be kept safe on any cloud storage, can be viewed and used anytime.
- 3D View: CAD aids in fashioning 3D objects with colors, materials/textures used on a plethora of surfaces.
- Revisions and Modifications: In CAD, the in-built tools enable an amount of revisions and modifications quickly and easily.
- Speed: Time and effort can be saved by creating a re-usable block library. Edits can be done with the help of simple commands.
- Accuracy: CAD allows you to draw with fractional dimensions and also define accuracy to any number of decimal places.
Conclusion:
Although the entertainment industry is mostly responsible for the advances in 3D computer animation, they make up only a small part of the industry that uses 3D animations. Animation designs vend products; it has also used as a teaching aid because it represents information in a more apprehensible way.
Many animations can be created perfectly on a computer, but on the basis of the type of animation required, such as cartoon animations, there may be the requirement for some hand-penciling work to be done.
