In 3D computer graphics, 3D modeling is the process of developing a mathematical coordinate-based representation of a surface of an object (inanimate or living) in three dimensions via specialized software by manipulating edges, vertices, and polygons in a simulated 3D space. [1] [2] [3]
The objects in 3-D computer graphics are often referred to as 3-D models. Unlike the rendered image, a model's data is contained within a graphical data file. A 3-D model is a mathematical representation of any three-dimensional object; a model is not technically a graphic until it is displayed.
Four-dimensional space (4D) is the mathematical extension of the concept of three-dimensional space (3D). Three-dimensional space is the simplest possible abstraction of the observation that one needs only three numbers, called dimensions, to describe the sizes or locations of objects in the everyday world.
UV texturing is an alternative to projection mapping (e.g., using any pair of the model's X, Y, Z coordinates or any transformation of the position); it only maps into a texture space rather than into the geometric space of the object. The rendering computation uses the UV texture coordinates to determine how to paint the three-dimensional surface.
Depth of field – objects appear blurry or out of focus when too far in front of or behind the object in focus; Motion blur – objects appear blurry due to high-speed motion, or the motion of the camera; Non-photorealistic rendering – rendering of scenes in an artistic style, intended to look like a painting or drawing
The basic object used in mesh modeling is a vertex, a point in three-dimensional space.Two vertices connected by a straight line become an edge.Three vertices, connected to each other by three edges, define a triangle, which is the simplest polygon in Euclidean space.
A virtual hand that can select and re-locate virtual objects will work as well. 3D widgets can be used to put controls on objects: these are usually called 3D Gizmos or Manipulators (a good example are the ones from Blender). Users can employ these to re-locate, re-scale or re-orient an object (Translate, Scale, Rotate).
