3D modeling involves using computer simulation software to mathematically represent real-life objects in three dimensions - width, height, and depth along the x, y, and z axes. There are two main types of 3D models: solid models, which show objects realistically for CAD, and shell boundary models, which show just the surface. 3D modeling is widely used in computer games, simulations, and other fields to create highly detailed and realistic looking 3D graphics, animations, and virtual objects.

2. 3D means three dimensional if we talk in
general scientific terms. It is an extended form
of 2D in which the objects are represented
mathematically in two dimensions i.e. x and y
axis respectively. However in 3D modeling,
any kind of object can be represented
mathematically in the three dimensions which
are the x-axis, y –axis and the z-axis which
relates to the depth.

3. The process in which we represent an object
using 3d models involves the use of computer
simulation software. The computer simulation
software is a special kind of simulation
software through which we can express a real
life object on a computer in a virtual manner.
This helps to analyze and represent the object
properly across the three axis.

4. A 3d model is a graphical model on screen
that shows an object in a 3D environment.
The object being modeled is shown by a
collection of points which are related to each
other. These points are then connected by
lines to from a closed figure called ‘mesh’.
This method of computer graphics makes
various changes on an object regarding its
size, shape and location.

5. Scaling, transformation, rotation are a few
examples of the processes that are used to
represent an object in a 3D environment
altogether. There are two types of 3d models.
The first type of 3d model is a Solid model.
This type of model expresses an object in a
highly realistic manner. It is used for making
simulations for CAD which stands for
Computer Aided Design. Shell boundary is
the second type of 3d model that is used to
show any object in a 3D space.

6. The shell boundary model shows the surface
element of an object. The 3D modeling
technique is extensively and widely used in
various field of computer science which
makes use of 3D graphics. The computer
games are a fine example of 3D modeling. In
PCgames, the animations and objects that we
see look very realistic and resemble quite
similar to the real life objects. This has all
been possible due to the applications of 3D
modeling.

7. The user viewing is also enhanced to a much
higher level and they are able to see better
graphical animations. The detailing of the
graphics of an object also increases with 3D
modeling and so the viewer is able to see
stunning graphics being rendered or
displayed on the computer screen. Therefore,
3D modeling is a very popular application of
computer graphics.
