Common 3D Modeling Techniques
3D Modeling should be understood as a process of creating a comprehensive mathematical model of some object or surface. Now there is a large amount of various common 3D modeling techniques that greatly improve the modeling process.
5 Best Common 3D Modeling Techniques used in Filming and Gaming
1. Digital Sculpting
Digital Sculpting technique allows artists to create meshes manually with the help of a tablet and model characters and antiheroes, animals and various creatures with sculptural accuracy. Digital sculpting makes modeling more rapid and effective. Besides, an artist can perform his job using its facilities and create millions of polygons.

2. Box Modeling (Subdivision Modeling)
Box modelling is one of the most trivial 3D methods. It is a polygonal method when 3D artists take a simple geometric shape as a basis. For example sphere parallelepiped, cube, cone and other items. After that, they purify and improve the shape just before they reach the desired form of an object.
Artists that use such technique frequently divide their work into steps. First, they took a low-resolution mesh as an essential element, and then a 3D master improves the shape of an object to make it close to the one he imagines it to be. Finally, an artist makes the mesh smaller to make sharp edges smoother and accumulate more details to the figure. The process can be repeated as many times as needed to create a correct polygonal interpretation of the desired concept.

3. Contour Modeling (Edge Modeling)
Unlike the modeling type we mentioned before where a user should develop a simple model, edge modeling supports the concept that 3D models should be created the element by element by placing loops on facets and occupy spaces between gaps.
This technique is rather tricky. However, it helps artists to create more detailed and well-legible models. Besides, 3D professionals often combine the edge and box modeling since it could sometimes be hard to achieve the desired results by using box method only.
For instance, a face of a human or a muzzle of an animal or a creature is extremely challenging to model. To construct them properly and fast an artist should first define dominating exterior features like eyes, nose, ears, lips, etc., and then remaining model aspects of an appearance.

4. NURBS Modeling (Spline Modeling)
NURBS method is primarily used in mechanical, industrial and automobile 3D modeling. The mesh of the model is smooth and formed by moving of surfaces between a numbers of so-called splines.
NURBS curves are created with a tool that works similarly to the pen tool in Adobe Illustrator. The curve is drawn in 3D space and edited by moving a series of handles called control vertices. To model a NURBS surface, the artist places curves along prominent contours, and the software automatically interpolates the space between.
This is a common 3D modeling technique for objects that are radial in nature—vasas, wine glasses, plates, etc.

5. Image-Based Modeling
Image-Based modeling represents conversation and transformation of a set of 2D pictures into a complete 3D object. Such modeling usually finds it’s applying in cases when there is no much time or money for manual 3D production. The greatest and almost legendary example of an image based technique is “The Matrix” movie when the scene was filmed using 360-degree equipment, and then 3D artists generated a virtual camera tool to make it looks 3D realistic.
