What is 3d modeling?
​
It is the process of developing graphics and images that appear to have three dimensions.

The process is complicated, but generally involves connecting a set of points with various geometric data such as lines and curved surfaces with the goal of creating a wide frame model that represents a three-dimensional object.

The end product can be either animate or inanimate, but is typically, characterized by its life-like look and apparent depth.


WHERE IS IT USED?
​
- video gaming
- motion pictures and movies
- architecture and design
- medicine
- engineering


In most cases it requires both specialized software and at least some knowledge of computer coding.
