Non-uniform rational basis spline (NURBS) is a mathematical model commonly used in computer graphics for generating and representing curves and surfaces.

It offers great flexibility and precision for handling both analytic (surfaces defined by common mathematical formulae) and modeled shapes.

NURBS are commonly used in computer-aided design (CAD), manufacturing (CAM), and engineering (CAE) and are part of numerous industry wide standards, such as IGES, STEP, ACIS, and PHIGS.

NURBS tools are also found in various 3D modeling and animation software packages.

In 3D computer graphics, 3D modeling (or three-dimensional modeling) is the process of developing a mathematical representation of any three-dimensional surface of an object (either inanimate or living) via specialized software.

The product is called a 3D model.

It can be displayed as a two-dimensional image through 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.

Rhinoceros (typically abbreviated Rhino, or Rhino3D) is a commercial 3D computer graphics and computer-aided design (CAD) application software developed by Robert McNeel & Associates; an American, privately held, employee-owned company, that was founded in 1980.

Rhinoceros geometry is based on the NURBS mathematical model, which focuses on producing mathematically precise representation of curves and freeform surfaces in computer graphics (as opposed to polygon mesh-based applications).

Rendering or image synthesis is the process of generating an image from a 2D or 3D model (or models in what collectively could be called a scene file) by means of computer programs.

Also, the results of such a model can be called a rendering.

A scene file contains objects in a strictly defined language or data structure; it would contain geometry, viewpoint, texture, lighting, and shading information as a description of the virtual scene.

The data contained in the scene file is then passed to a rendering program to be processed and output to a digital image or raster graphics image file.

The term "rendering" may be by analogy with an "artist's rendering" of a scene.

Though the technical details of rendering methods vary, the general challenges to overcome in producing a 2D image from a 3D representation stored in a scene file are outlined as the graphics pipeline along a rendering device, such as a GPU.

A GPU is a purpose-built device able to assist a CPU in performing complex rendering calculations.

If a scene is to look relatively realistic and predictable under virtual lighting, the rendering software should solve the rendering equation.

The rendering equation doesn't account for all lighting phenomena, but is a general lighting model for computer-generated imagery.

'Rendering' is also used to describe the process of calculating effects in a video editing program to produce final video output.

A polygon mesh is a collection of ', s and s that defines the shape of a polyhedral object in 3D computer graphics and solid modeling.

The faces usually consist of triangles (triangle mesh), quadrilaterals, or other simple convex polygons, since this simplifies rendering, but may also be composed of more general concave polygons, or polygons with holes.
