Modeling software is a category of computer application used to produce 3D models. This category of software is called modeling or modeling applications.
Three-dimensional models represent an object using a set of points in 3D space, interconnected with geometric shapes such as triangles, lines, and curved surfaces. They can be created by hand, mathematically (procedural modeling), or scanned . 
3D models are widely used in 3D graphics. Many computer games use images produced from 3D models.
Today, 3D models are used in a wide variety of fields. In the medical industry, detailed models of devices are used where multiple two-dimensional slices of an image are created from an MRI or CT scan .
– The film industry uses modeling to create moving characters and objects in motion pictures .
– The video game industry uses it for computer and video games. The science sector uses them as detailed models for chemical compounds .
– The architecture industry uses it to demonstrate proposed buildings and landscapes through architectural modeling software.
– As well as a host of other uses. In recent decades the Earth science community has begun to build 3D geological models. It can also be 3D models of physical devices that are built with 3D printers or manufacturing machines based on using the computer .
