Mesh construction involves creating 3D objects using polygon meshes made of different elements like vertices, edges, faces, polygons and surfaces. A vertex defines a point in 3D space, an edge connects two vertices, a face is a closed set of edges forming triangles or quads. Polygonal modelling represents 3D objects as meshes of polygons that can be rendered in real-time. Box modelling takes a basic shape like a box and sculpts the final model from it through repeated refinement, while edge modelling directly connects points without refinement. 3D scanners can also be used to digitally capture real-world objects.
Three-dimensional (3D) printing is an additive manufacturing process that creates a physical object from a digital design. The process works by laying down thin layers of material in the form of liquid or powdered plastic, metal or cement, and then fusing the layers together.
3D printing is any of various processes in which material is joined or solidified under computer control to create a three-dimensional object ,with material being added together (such as liquid molecules or powder grains being fused together), typically layer by layer. In the 1990s, 3D printing techniques were considered suitable only for the production of functional or aesthetical prototypes and a more appropriate term was rapid prototyping

Overview on Various Types of 3D Modeling TechniquesThePro3DStudio
3D modeling has a varied range of applications, ranging from video games, animated movies, publishing, architecture, healthcare and medical science, scientific research, and many more. But have you wondered how the technology works? How do 3D artists create such impressive, lifelike models? To get these answers, you must know what 3D modeling is and the various 3D modeling techniques involved in developing such realistic 3D characters. At first, all these might seem a little tricky. However, once you have a solid understanding, you can delve deeper into 3D modeling and rendering technologies and build a lucrative career out of it. Check out this detailed article about 3D modeling and the various techniques involved in the process.
In these days 3D modeling reaches its mainstream popularity. It is wildly used in both gaming and movie environment as well as in science and engineering sectors.
3D Modeling Techniques : Types and Specific ApplicationsThePro3DStudio
3D modeling has revolutionized the design, manufacturing, research & development, and the advertising industries. With 3D modeling, it is now possible to visualize an outcome even before it is given a practical, real shape. 3D modeling allows inventors and designers to evaluate their concepts and to identify potential flaws that may lead to project failure at a later stage. These slides provide details about the various types of 3D modeling techniques and their specific uses and applications.
3D models are used for a variety of mediums including video games, movies, architecture, illustration, engineering, and commercial advertising. The 3D modeling process produces a digital object capable of being fully animated, making it an essential process for character animation and special effects.
Digitization is one the way by which heritage and important places, sits, things, statues, objects, etc. can be
prevented from degradation. There are many software’s available in market for the modeling of objects but in this
study Autodesk 3DS Max was used for modeling the objects used by Dr. Babasaheb Ambedkar which are
preserved in Milind College of Arts and Science in Aurangabad, India.

1. Mesh Construction
Mesh construction is the process of creating objects with polygon meshes; these polygons are
different forms of elements. The elements are vertices, edges, faces, polygons and surfaces.
Polygon Modelling
A vertex is a position along with other information such as colour, normal vector and texture
coordinates. An edge is a connection between two vertices. A face is a closed set of edges, in which a
triangle face has three edges, and a quad face has four edges. A polygon is a set of faces. In systems
that support multi-sided faces, polygons and faces are equivalent. However, most rendering
hardware supports only 3- or 4-sided faces, so polygons are represented as multiple faces.
Mathematically a polygonal mesh may be considered an unstructured grid, or undirected graph,
with addition properties of geometry, shape, and
topology.http://scotty1108.wordpress.com/3d/mesh-construction/

Box modelling Technique:
Box modelling knowledge - Box modelling is where you take a basic primitive shape (like a box,
cylinder or others) and make the basic shape “rough draft” of your final model from there you sculpt
out your final model. The process uses various tools and steps that sometimes get repeated again
and again until you’re done. Despite the fact you’re repeating these steps you will model faster and
control the amount of detail you wish to add, slowly building your model up from ground level of
detail to high level.
The other method is Edge modelling which is placing out points and connecting the dots. There is
no repeat of steps to refine the model to the level of detail you need, its created right on the spot
when you place your points and faces. I recommend that if your using this technique to use it to get
to your Rough detail Stage.

2. Polygon Modelling
Description - In 3D computer graphics, polygonal modelling is an approach for modelling objects by
representing or approximating their surfaces using polygons. Polygonal modelling is well suited to
scanline rendering and is therefore the method of choice for real-time computer graphics. Alternate
methods of representing 3D objects include NURBS surfaces, subdivision surfaces, and equation-
based representations used in ray tracers. See polygon mesh for a description of how polygonal
models are represented and stored.
Primitive Modelling
Primitives are the building blocks of 3D—basic geometric forms that you can use as is or modify with
transforms and Booleans .Although it's possible to create most of these objects by lathing or
extruding 2D shapes, most software packages build them in for speed and convenience.
All the main aspects of the modelling process are using shapes like – cubes,
cylinders, pyramids, spheres and squares / rectangles.

Specialised Modelling with 3D scanners
The use of 3D imaging has become increasingly common in various industries. Here is a sample of
case studies where our 3D scanners have been particularly helpful in these applications. Customers
can expect similar results when using the 3D scanners for other applications.
Similar technology is sometimes used for video games to get a good quality product for the in game
design. It also saves a lot of time instead of design an object; the scanner does it for you almost.
These methods are also used for dentists and hospitals for medical needs. But the video gaming
works well for how it’s supposed to look.
