Polygons are used in computer graphics to compose images that are three-dimensional in appearance, [1] and are one of the most popular geometric building blocks in computer graphics. [2] Polygons are built up of vertices, and are typically used as triangles. A model's polygons can be rendered and seen simply in a wire frame model, where the ...
Example of a low poly triangle mesh representing a dolphin. In 3D computer graphics and solid modeling, a polygon mesh is a collection of vertices, edge s and face s that defines the shape of a polyhedral object's surface. It simplifies rendering, as in a wire-frame model.
A polygon mesh of a dolphin. In 3D computer graphics, polygonal modeling is an approach for modeling objects by representing or approximating their surfaces using polygon meshes. Polygonal modeling is well suited to scanline rendering and is therefore the method of choice for real-time computer graphics.
In 3D computer graphics, a wire-frame model (also spelled wireframe model) is a visual representation of a three-dimensional (3D) physical object. It is based on a polygon mesh or a volumetric mesh, created by specifying each edge of the physical object where two mathematically continuous smooth surfaces meet, or by connecting an object's constituent vertices using (straight) lines or curves.
The top of a car hood is an example of a surface open in both directions. Surfaces closed in one direction include a cylinder, cone, and hemisphere. Depending on the direction of travel, an observer on the surface may hit a boundary on such a surface or travel forever. Surfaces closed in both directions include a sphere and a torus.
Polygon visibility in a given viewport: a) polygon fills the viewport, b) polygon partially and c) completely visible, d) polygon invisible. Four steps of a viewport divisions for a simple scene. The Warnock algorithm is a hidden surface algorithm invented by John Warnock that is typically used in the field of computer graphics. [1]

Computer graphics deals with generating images and art with the aid of computers.Computer graphics is a core technology in digital photography, film, video games, digital art, cell phone and computer displays, and many specialized applications.
This is a list of models and meshes commonly used in 3D computer graphics for testing and demonstrating rendering algorithms and visual effects. Their use is important for comparing results, similar to the way standard test images are used in image processing.
