3D modeling is a technique in computer graphics for producing a 3D digital representation of any object or surface.
An artist uses special software to manipulate points in virtual space(called vertices) to form a mesh: a collection of vertices that form an object.
These 3D objects can be generated automatically or created manually by deforming the mesh, or otherwise manipulating vertices.
3D models are used for a variety of mediums including video games, movies, architecture, illustration, engineering, and commercial advertising.
The 3D modeling process produces a digital object capable of being fully animated, making it an essential process for character animation and special effects.
The core of a model is the mesh which is best described as a collection of points in space.
download free 3d models creative common license are mapped into a 3D grid and joined together as polygonal shapes, usually triangles or quads. Each point or vertex has its own position on the grid and by combining these points into shapes, the surface of an object is created.
Models are often exported to other software for use in games or movies. But some 3D modeling programs allow the creation of a 2D images using a process called 3D rendering. This technique is fantastic for creating hyper-realistic scenes using sophisticated lighting algorithms.
