Interactive means are interrelated. This means that between the user users and media
programs there is a reciprocal relationship, the user provides a response to the demand media display
program, then proceed with the presentation of information next concept presented by the media
programs are [3].
Entrance exam is a test to determine whether or not a person acceptable candidates wishing to enter
the school, offices, companies and so on [4]. In the 3-dimensional design space we will
know the three axis coordinates of the axis x, axis y, and z-axis [5].
2.2 3D Modeling In 3D computer graphics, 3D modeling is the process
of developing a mathematical representation of each of the three-dimensional object either inanimate or
living via specialized software. This product is referred to as 3D models. See objects in three
dimensions 3D means seeing the object in true form. 3D depiction would be helpful to clarify the
intent of actually visualized. 3D depiction is a further development
of 2D
drawing.
Figure 2.1 Comparison of 2D and 3D object
appearance 3D modeling process requires the design of which is
shared by several stages to its formation. As the object what you want to set up a basic object, method
of 3D object modeling, lighting and animation object motion in the order process to be performed.
Figure 2.2 3D Modeling Process
The purpose and function of each part is a process that
will be
explained as
follows:
a. Motion Capture Model 2D , which is the first
step to determine the shape of the object model to be built in 3D. In this stage of the process of determining
the 2D object has a sense that the 2D object that will be formed is the basis for 3D modeling.
b. Basic 3D Modelling Method
, There are several methods used for 3D modeling. There are types of
object modeling method tailored to his needs like with NURBS and polygons. Modeling polygon is a
triangle and square shapes that determine the surface area of a character. Each polygon determines a flat
field by putting a line of polygons so that we can create the surface forms. To obtain a smooth surface,
it takes a lot of polygons. When only using a few polygons, the object will be divided into several
fractions obtained polygon. While modeling with NURBS Non-Uniform Rational Bezier Spline is the
most popular method to construct an organic model. On the NURBS curve can be formed with only three
points only. Compared with polygon curve which requires a lot of points vertices, this method makes
it easier to control. One point of CV control vertices to control one area to the texture.
