Which describes the third step in visual character development

creating a 3D model of the character.

Explanation:

3D modeling is a technique in computer graphics for producing a 3D digital representation of an object.

A special software is used to manipulate points in virtual space(called vertices) to form a mesh. MESH is a collection of vertices that form an object.

3D objects can be generated automatically or manually by deforming the mesh, or manipulating vertices.

3D models are used for a variety of mediums including video games, MOVIES, architecture, illustration, engineering, and commercial advertising.
