3D modelers are used in a broad range of industries. The medical business uses them to create thorough models of organs. The movie industry uses them to create and maneuver characters and objects for animated and real-life motion pictures. The video game industry uses them to generate assets for video games. The science sector uses them to create extremely detailed models of chemical compounds. The architecture industry uses them to create models of projected buildings and landscapes. The engineering society uses them to intend novel devices, vehicles and structures as well as a host of other uses. There are usually many stages in the "pipeline" that studios and manufacturers use to create 3D objects for film, games, and production of hard goods and structures.
Several 3D modelers are general-purpose and can be used to generate models of a range of real-world entities, from plants to automobiles to people. Some are exclusively designed to model certain objects, such as chemical compounds or internal organs.
3D modelers permit users to generate and alter models by means of their 3D mesh. Users can stretch, add, subtract, and or else modify the mesh to their desire. Models can be viewed from a variety of angles, generally simultaneously. Models can be rotated and the sight can be zoomed in and out.
3D modelers can export their models to files, which can then be imported into other applications as long as the metadata is well-matched. Several modelers permit importers and exporters to be plugged-in, so they can read and write data in the native formats of other applications.
Majority 3D modelers contain a number of related features, such as ray tracers and other rendering alternatives and texture mapping facilities. Some also enclose features that support or allow animation of models. Some may be able to produce full-motion video of a series of rendered scenes (i.e. animation) Shown in below (Figure 1).

Hardware and software are two of the input factors that conclude the excellence of
computer animation that is fashioned. As both of this method work in conjunction with each other it is important to make the right choice for a product that is of lasting quality and accuracy.
Hardware comes in many shapes, sizes, and capabilities. Numerous hardware is specialized to do only certain tasks while other hardware are equipped for a variety of things. Some of the commonly used hardware are:
6.2.1 Silicon Graphics Inc (SGI):
The SGI platform is one of the most widely used platforms for quality computer
animation productions. SGI computers operate using the wide spread UNIX system.
Produced by Silicon Graphics these computers are enormously fast and produce excellent
results. They come in a range of types, ranging from the general purpose Indy to high
power Indigo Extreme that is used for animations. Onyx is an additional type, which is suited to the complex calculations involved in rendering. Some of the software like Alias, Wavefront, and SoftImage are ran on SGI's.
PC's are very versatile machines combining flexibility and power. PC's have established to be very functional for little companies and businesses as platforms to do computer
animation. Applications such as Animator Studio and 3DStudio are used on PC's to
Mac's were initially designed for graphic and desktop publishing and hence are attractive
useful platforms for producing computer graphics and animation software. Few of these
applications that work well on Mac's are Adobe Products like; Photoshop and Premiere
and Strata with Strata Studio Pro.
Originally owned by Commodore, Amiga computers have held a position in the computer
animation for long. The two software packages that Amiga is allied with are: Video
Toaster, and Light Wave 3D. The novel d'Amiga systems has been customized to be a
great graphics machine.
Sophisticated hardware has to be coupled with a good software to produce good results.
There are literally hundreds of computer animation and graphic software packages.

3d studio and Rendering box
Autodesk 3ds Max, previously 3D Studio MAX, is a modeling, animation and rendering package developed by Autodesk Media and Entertainment.
Early history & Releases
The novel 3D Studio product was created for the DOS stand by the Yost Group and published by Autodesk. Ensuing to 3D Studio Release 4, the product was rewritten for the Windows NT platform, and re-named "3D Studio MAX." This version was also initially created by the Yost Group. It was released by Kinetix, which was at that time Autodesk's dissection of media and entertainment. Autodesk purchased the product at the second release spot of the 3D Studio MAX version and internalized development entirely over the next two releases. In a while, the product name was changed to "3ds max" (all lower case) to better comply with the naming conventions of Discreet, a Montreal-based software company which Autodesk had purchased. At release 8, the product was again identified with the Autodesk logo, and the name was again changed to "3ds Max" (upper and lower case). At release 2009, product name distorted to "Autodesk 3ds Max".
3ds Max is the third most widely-used off the shelf computer animation program by content creation professionals according to the Roncarelli report. It has rough modeling capabilities, a supple plugin architecture and a long heritage on the Microsoft Windows platform. It is typically used by video game developers, TV commercial studios and architectural visualization studios. It is also used for movie pre-visualization and movie effects.
In adding up to its modeling and animation tools, the most recent version of 3ds Max also features superior shaders (such as ambient occlusion and subsurface scattering), dynamic simulation, particle systems, radiosity, normal map creation and rendering, global illumination, an intuitive and fully-customizable user interface, and its own scripting language. A plethora of dedicated third-party renderer plugins, such as V-Ray, Brazil r/s , Maxwell Render, and finalRender, may be purchased separately.
6.3.1 Polygon modeling
Polygon modeling (Figure 2) is more common with game design than any other modeling technique as the very specific control over individual polygons allows for extreme optimization. Generally, the modeller begins with one of the 3ds max primitives, and using such tools as bevel and extrude, adds detail to and refines the model. Versions 4 and up feature the Editable Polygon object, which simplifies many mesh editing operations, and provides subdivision smoothing at customizable levels.
Figure 2: Polygon modeling
Version 7 initially offers the edit poly modifier, which allows the use of the tools available in the editable polygon object to be used higher in the modifier stack (i.e., on top of other modifications).
6.3.2 NURBS or Non Uniform Relational B-Spline
A added advanced substitute to polygons, it gives a smoothed out outside that eliminates the straight edges of a polygon model. NURBS is a mathematically exact representation of freeform surfaces like those used for car bodies and ship hulls, which can be precisely reproduced at any resolution whenever needed. With NURBS, a flat sphere can be created with only one face.
The non-uniform possessions of NURBS bring up an important point. Since they are generated mathematically, NURBS objects have a parameter space in addition to the 3D geometric space in which they are displayed. Exclusively, an array of values called knots specifies the extent of influence of each control vertex (CV) on the curve or surface. Knots are imperceptible in 3D space and you can't manipulate them directly, but occasionally their behavior affects the visible appearance of the NURBS object. Parameter space is one-dimensional for curves, which have merely a single U dimension topologically, even though they exist geometrically in 3D space. Surfaces have two dimensions in parameter space, known as U and V.
NURBS curves and surfaces have the significant properties of not changing under the standard geometric affine transformations (Transforms), or under perspective projections. The CVs have local control of the object: moving a CV or changing its heaviness does not affect any part of the object beyond the neighboring CVs. (You can override this property by using the Soft Selection controls.) in addition, the control lattice that connects CVs surrounds the surface. This is acknowledged as the convex hull property.
6.3.3 Surface tool/Editable patch object
Surface tool was initially a 3rd party plugin, but Kinetix acquired and included this feature since version 3.0. The surface tool is for creating general 3ds max's splines, and then applying a modifier called "surface." This modifier makes a surface from every 3 or 4 vertices in a grid. This is repeatedly seen as an alternative to 'Mesh' or 'Nurbs' modeling, as it enables a user to interpolate curved sections with straight geometry (for example a hole through a box shape). Though the surface tool is a useful way to generate parametrically accurate geometry, it lacks the 'surface properties' found in the similar Edit Patch modifier, which enables a user to maintain the original parametric geometry whilst being able to adjust "smoothing groups" between faces.
The default rendering technique in 3DS Max is scanline rendering. Numerous advanced features have been added to the scanliner over the years, such as global illumination, radiosity, and ray tracing.
mental ray is a production quality renderer integrated into the later versions of MAX, and is a powerful rendering tool, with bucket rendering, a technique that distributes the rendering burden between several computers efficiently. The 3ds Max version of mental ray also comes with a set of tools that permit a myriad of effects to be created with relative ease.
A third party connection tool to RenderMan pipelines is also available for those that need to integrate Max into Renderman render farms.
A third-party cause to be engine plug-in for 3D Studio MAX. It is broadly used, frequently substituting the standard and mental ray renderers which are included bundled with 3ds Max. V-Ray continues to be well-matched with older versions of 3ds Max.
