Polygon mesh is a collection of vertices and edges that make up the surface of the shell of the polygon model. Modeling processes use simplified surfaces allow rendering to occur with ease, as the simple surfaces can be transformed to move the way that the artist would like. A complete structure not only requires surfaces, but edges, polygons and vertices.
There are six aspects of mesh modeling, these include: vertices, edges, faces, polygons, surfaces and vertexes. These aspects become combined to create the polygon mesh that can be molded to the perspective of the artist. One or all of these aspects may be incorporated into the 3D model to create a full structure, which can be rendered.
A polygon is a set of faces on the mesh of the model. Faces are the different sides of the model, closed portions of the 3D model. Surfaces are the outside area of the model, and polygons are the shape of the model, as a whole - they assist in smoothing the outside of the model. Lastly, the vertices are points in the model used to coordinate faces and edges.
There are six ways that a polygon model may be represented. These are; face-vertex meshes, which are a simplified list of vertices and a list of polygons. Winged edge meshes refer to one of the heaviest of polygon representations and use two vertices, and two edges. Half edge meshes are similar to winged-edge meshes, using half of the information. Corner table meshes are the easiest meshes to convert, and the lightest but can be difficult to use, using a table to map the vertices. Quad-edge meshes use only half edges on the surface mesh. Vertex to vertex meshes is the simplest mesh to form, and are a primitive modeling form - where vertices are connected only to other vertices.
About 3D Modeling Methods
There are three methods used to create 3D models. Although these methods are considerably different, there are many similar aspects through the creation process. It is hard to say which technique is preferred, as it would depend on the 3D modeler, but polygonal modeling processes come as the easiest to render, and NURBS models are the most detailed. In between these two, we have spline modeling, which incorporates the techniques of both modeling methods.
The first type of 3D modeling, spline modeling which falls right in the middle of the three forms of modeling. It is between NURBS modeling and spline modeling as it uses techniques of both, and implements curved lines to create the functional 3D models. When it comes to the rendering process, the spline modeling method is second easiest to convert, making it a popular choice for modelers.
The second type of 3D modeling, polygon modeling uses points within the 3D space referred to as vertices, which are connected by lines - that work together to create a 3D mesh. Many modelers prefer this type, as they are very flexible, and the models can be rendered quicker than other forms of modeling. This means, that they can be made to move within a background, as the cells can be transitioned quite easily. Many, many polygons create a 3D model in this type of modeling. The majority of models that are built are built through this method, because of the flexibility that comes with polygonal modeling.
Lastly, the third type of 3D modeling is, NURBS Modeling and has grown in popularity, not only because of the effective procedures, but because of the transformation can occur throughout the process, making NURBS models some of the most versatile. Using the NURBS method of modeling creates curves with weighted points on the vertices of the model. It is preferred for detailed surfaces, as it creates actual curves, not tiny lines in a curve like appearance such as other types.

Spline Interpolation $100.37 High Quality Content by WIKIPEDIA articles In the mathematical field of numerical analysis, spline interpolation is a form of interpolation where the interpolant is a special type of piecewise polynomial called a spline. Spline interpolation is preferred over polynomial interpolation because the interpolation error can be made small even when using low degree polynomials for the spline. Thus, spline interpolation avoids the problem of Runges phenomenon which occurs when using high degree polynomials. Using polynomial interpolation, the polynomial of degree n which interpolates the data set is uniquely defined by the data points. The spline of degree n which interpolates the same data set is not uniquely defined, and we have to fill in n1 additional degrees of freedom to construct a unique spline interpolant.

Spline (Mathematics) $78.07 High Quality Content by WIKIPEDIA articles In mathematics, a spline is a special function defined piecewise by polynomials. In interpolating problems, spline interpolation is often preferred to polynomial interpolation because it yields similar results, even when using lowdegree polynomials, while avoiding Runges phenomenon for higher degrees.In n the computer science subfields of computeraided design and computer graphics, the term spline more frequently refers to a piecewise polynomial (parametric) curve. Splines are popular curves in these subfields because of the simplicity of their construction, their ease and accuracy of evaluation, and their capacity to approximate complex shapes through curve fitting and interactive curve design.

Cubic Hermite Spline $68.51 High Quality Content by WIKIPEDIA articles In the mathematical subfield of numerical analysis a cubic Hermite spline (also called cspline), named in honor of Charles Hermite, is a thirddegree spline with each polynomial of the spline in Hermite form. The Hermite form consists of two control points and two control tangents for each polynomial. For interpolation on a grid with points xk for k = 1,...,n, interpolation is performed on one subinterval (xk,xk + 1) at a time (given that tangent values are predetermined). The subinterval (xk,xk + 1) is normalized to (0,1) via t = (x ? xk) / (xk + 1 ? xk).
