3D is required by a lot of different industries to help them advance and make designing using and

presenting different items or products easy and productive.

Science benefits from 3D by using it in the medical industry for displaying CGI animations of internal

organs and processes inside the body which is helpful for making more decise and swift choices and

makes operating easier to do.

In education Science experiments are shown through this 3D animation. The 3d animation company

used thousands of highly animated lesson specific, 3d & 2d multimedia modules that allow the

teachers to effectively explain the lessons in the classrooms.

Within gaming 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 modelling), or scanned.

3D graphics can give web page designs a range of 3D illusions, which are powerful devices for managing attention. Using 3D graphics in web design can also add significantly to overall page file

size, and can reduce usability if overused, so should be used deliberately and with care.

Engineering industries, especially mechanical engineering based companies, use CAD in a variety of ways. Right from creating engineering drawings to 3D modelling, CAD is used in most of the

manufacturing process

In the past, architecture was a three-dimensional discipline that relied on drawings and models to convey information. The development of the computer and architectural software, such as

Computer Aided Design (CAD) and Building Information Modeling (BIM), has completely changed the profession.

3D product design enables conceptual designers, engineering, manufacturing, sales and marketing departments to explore a complete product in great detail before a final product is ever built.

3D-ready TV sets are those that can operate in 3D mode (in addition to regular 2D mode) using one of several display technologies to recreate a stereoscopic image. These TV sets usually

support HDMI 1.4 and a minimum output refresh rate of 120 Hz; glasses may be sold separately.

is a motion picture that enhances the illusion of depth perception. Derived from stereoscopic photography, a regular motion picture camera system is used to record the images as seen from two perspectives (or computer-generated imagery generates the two perspectives in post-production),

and special projection hardware and/or eyewear are used to provide the illusion of depth when viewing the film. 3D films are not limited to feature film theatrical releases; television broadcasts

and direct-to-video films have also incorporated similar methods, especially since 3D television and Blu-ray 3D.

Direct 3D is only available for Windows 95 and up and that it renders 3D graphics especially in gaming as it uses the Graphics card. It all started in 1992 with Servan Keondjian who started a company called RenderMorphics and they developed a 3D graphical Application

programming interface (API for short), It was used in medical imaging and CAD (computer aided design) software. Two versions of this API were released. And in February 1995 Microsoft bought RenderMorphics. When Direct3D was used to render they used a thing called a Buffer to render 3D geometry but the process was AWKWARD and had complex stages that you have to do manually and so Open GL was made to make it simpler.

Geometric group theory is an area in mathematics devoted to the study of finitely generated groups via exploring the connections between algebraic properties of such groups and topological and geometric properties of spaces on which these groups act (that is, when the groups in question are realized as geometric symmetries or continuous transformations of some spaces).

Another important idea in geometric group theory is to consider finitely generated groups themselves as geometric objects. This is usually done by studying the Cayley graphs of groups, which, in addition to the graph structure, are endowed with the structure of a metric space, given by the so-called word metric.

Geometric group theory, as a distinct area, is relatively new, and has become a clearly identifiable branch of mathematics in late 1980s and early 1990s. Geometric group theory closely interacts with low-dimensional topology, hyperbolic geometry, algebraic topology, computational group theory and geometric analysis. There are also substantial connections with complexity theory, mathematical logic, the study of Lie Groups and their discrete subgroups, dynamical systems, probability theory, K-theory, and other areas of mathematics.

A polygon mesh or unstructured grid is a collection of vertices, edges and faces that defines the shape of a polyhedral object in 3D computer graphics and solid modelling. The faces usually consist of triangles, quadrilaterals or other simple convex polygons, since this simplifies rendering, but may also be composed of more general concave polygons, or polygons with holes.

The study of polygon meshes is a large sub-field of computer graphics and geometric modelling. Different representations of polygon meshes are used for different applications and goals. The variety of operations performed on meshes may include Boolean logic, smoothing, simplification, and many others. Network representations, "streaming" and "progressive" meshes, are used to transmit polygon meshes over a network. Volumetric meshes are distinct from polygon meshes in that they explicitly represent both the surface and volume of a structure, while polygon meshes only explicitly represent the surface (the volume is implicit). As polygonal meshes are extensively used in computer graphics, algorithms also exist for Ray tracing, collision detection, and rigid-body dynamics of polygon meshes

In conclusion i think that 3D is extremely helpful for everyday life today and with its constant development its only going to get better allowing us to go into even more and more detail to deliver the best quality of service from a wide variety of professions.
