3D computer graphics software is used to make computer-generated imagery for movies, etc. Recent availability of CGI software and increased computer speeds has allowed individual artists and small companies to produce professional-grade films, games, and fine art from their home computers. This has brought about an Internet subculture with its own set of global celebrities, clichés, and technical vocabulary.

3D models represent a 3D object using a collection of points in 3D space, connected by various geometric entities such as triangles, lines, curved surfaces, etc. Being a collection of data (points and other information), 3D models can be created by hand, algorithmically (procedural modeling), or scanned.

3D models are widely used anywhere in 3D graphics. Actually, their use predates the widespread use of 3D graphics on personal computers. Many computer games used pre-rendered images of 3D models as sprites before computers could render them in real-time.

Today, 3D models are used in a wide variety of fields.

The medical industry uses detailed models of organs.

The movie industry uses them as characters and objects for animated and real-life motion pictures.

The video game industry uses them as assets for computer and video games.

The science sector uses them as highly detailed models of chemical compounds. In recent decades the earth science community has started to construct 3D geological models as a standard practice.

The architecture industry uses them to demonstrate proposed buildings and landscapes through Software Architectural Models.

The engineering community uses them as designs of new devices, vehicles and structures as well as a host of other uses.

Education: In addition to the novelty factor, the extra information in 3D images can greatly enhance an

educational experience. The immersive nature of 3D images engages the viewer, encouraging them to view the

images longer and more deeply, and the enhanced visualizations make for more memorable learning.

Medicine: Scientists, hospital staff and patients benefit from the use of systems that present information in

understandable formats by exploiting a unique combination of 3D technology, science, and software

engineering.

3D CT imaging in human medicine is mainstream and used in numerous applications such as vascular studies,

cardiac imaging, virtual endoscopy, and presurgical planning. 3D imaging in veterinary medicine is far less

common. This is likely because of the fact that newer CT machines are necessary to generate diagnostic images

and the applications for 3D CT are different.

Architecture: Digital architecture uses computer modeling, programming, simulation and imaging to create both virtual forms and physical structures. The terminology has also been used to refer to other aspects of architecture that feature digital technologies.

3D "dumb" solids are created in a way analogous to manipulations of real world objects (not often used today). Basic three-dimensional geometric forms (prisms, cylinders, spheres, and so on) have solid volumes added or subtracted from them, as if assembling or cutting real-world objects. Two-dimensional projected views can easily be generated from the models. Basic 3D solids don't usually include tools to easily allow motion of components, set limits to their motion, or identify interference between components.

3D parametric solid modeling requires the operator to use what is referred to as "design intent". The objects and features created are adjustable. Any future modifications will be simple, difficult, or nearly impossible, depending on how the original part was created. One must think of this as being a "perfect world" representation of the component. If a feature was intended to be located from the center of the part, the operator needs to locate it from the center of the model, not, perhaps, from a more convenient edge or an arbitrary point, as he could when using "dumb" solids. Parametric solids require the operator to consider the consequences of his actions carefully.

We can create 3d Product Modelling Animation that will effectively showcase your product's function, storage and packaging. 3D product modelling is a practical technology used by a number of industries - movie industry for producing visual effects; engineering industry for 3D rendering of new devices, Render building plans or 3D Designs of vehicle entertainment industry for creating video and computer games; and medical industry for a detailed presentation of organs.

3D television (3DTV)

is television that conveys depth perception to the viewer by employing techniques such as stereoscopic display, multi-view display, 2D-plus-depth, or any other form of 3D display. 2D plus depth processing can be used to recreate 3D scenes even from a single view and convert legacy film and video material to a 3D look, though a convincing effect is harder to achieve and the resulting image will likely look like a cardboard miniature.

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. The two main methods of displaying 3d polygon models are OpenGL and Direct3D. Both of these methods can be used with or

without a 3d accelerated graphics card.

Geometric theory and Mesh Construction

Triangles always inhabit a single plane. The flat nature of triangles makes it simple to determine their surface normal, a three-dimensional vector perpendicular to the triangle's surface. Surface normals are useful for determining light transport in ray tracing, and are a key component of the popular Phong shading model. Some rendering systems use vertex normals instead of face normals to create a better-looking lighting system at the cost of more processing. Note that every triangle has two face normals, which are on the same line but opposite from each other. In many systems only one of these normals is considered valid – the other side of the polygon is referred to as a backface, and can be made visible or invisible depending on the programmer’s desires.

Many modeling programs do not strictly enforce geometric theory; for example, it is possible for two vertices to have two distinct edges connecting them, occupying exactly the same spatial location. It is also possible for two vertices to exist at the same spatial coordinates, or two faces to exist at the same location. Situations such as these are usually not desired and many packages support an auto-cleanup function. If auto-cleanup is not present, however, they must be deleted manually.

A group of polygons which are connected by shared vertices is referred to as a mesh. In order for a mesh to appear attractive when rendered, it is desirable that it be non-self-intersecting, meaning that no edge passes through a polygon. Another way of looking at this is that the mesh cannot pierce itself. It is also desirable that the mesh not contain any errors such as doubled vertices, edges, or faces. For some purposes it is important that the mesh be a manifold – that is, that it does not contain holes or singularities (locations where two distinct sections of the mesh are connected by a single vertex).

Polygon count:

Probably the single biggest problem new users face is polygon count. In 3DS MAX, the polygon count (that is the number of polygons in an object or scene) is not readily apparent. Get used to checking your polygon count by choosing more.

When you choose "Polygon Counter" from the "More" list, the window shown above will open. Note that this cow has over 5000 polygons!

A character in a 3D shooter is typically limited to 1000 polygons (or far less in older games, more in new ones). A VR world would typically have fewer polygons in the whole scene that this single cow has…
