3D modeling is the process of developing a mathematical representation of any three-dimensional object (whether inanimate or living) through specialized software. The product is called a 3D model. It can be viewed as a two-dimensional image using a process called 3D rendering, or used in a computer simulation of physical phenomena. The model can also be physically created using 3D printing devices.
We present these 10 free programs, ideal for both professionals and fans of 3D printing.
