Views and 2D and 3D views

What are Views and its types.
Visual Communication. Views and its types.

Views:

    

 The ability to see something or to be seen from a particular place or A sight or prospect,  that can be taken in by the eye from a particular place.

It is the extent or the range of the vision

There are two basic types of views.

2D  and 3d Views.

The 2D and 3D views are the center of the activities when you work with a map. They have a number of features that make working with them very comfortable and straightforward.

2D and 3D refer to the actual dimensions in a workspace. 2D is "flat", using the horizontal and vertical (X and Y) dimensions, the image has only two dimensions and if turned to the side becomes a line. 3D adds the depth (Z) dimension. This third dimension allows for rotation and visualization from multiple perspectives. It is essentially the difference between a photo and a sculpture.

The difference between 2d and 3d shapes is that, a 2d shape is flat, has no volume and depth and cannot be handled while a 3d shape can be held, has depth, volume and can hold things inside it. These are the dimensional shapes which are mostly used in geometry.

Fig 1.1

Fig 1.2

Here Figure 1.1 represents a two dimensional sketch of the car. Where we can see only X axis and Y-Axis of the co-ordinates, whereas fig.12 represents the 3-Dimensional picture (sketch ) of the car .

The key difference between 2D and 3D echocardiography is the volumetric approach to data acquisition and visualization.

Some of the geometrical 2d and 3d shapes and shown below. :

Fig 1.3

It is representing a 3 dimensional picture with all three, X, Y, and Z axis of angels with the arrows pointing the direction  It is the Z angle which is not in the 2-dimensional picture representation.

Fig 1.4

In this picture a triangle is represented by Just two co-ordiantes, X an y-axis co-ordinates. X-axis and Y-axis are labbed on the sides of the triangle.

Fig 2.1

This is a square representing X and Y co-ordinates of the AXIS . Here the arrows on the left and right side of the triangle represents the Y-Axis and the arrows on the top and bottom represents the X-Axis of the square.

                                            Fig 2.2

Figure 2.2 represents a 3-dimensional square with all 3 i.e X, Y and Z axis on the square. In 2-D image one is unable to see or get the depth of the image on the other hand 3-D image helps the man getting the distance, depth , height and details of the image from a specific distance. Here we represent the Y-Axis as the height of the square , X-Axis as the bottom and Z-Axis as the side view of the image.

Fig 3.1

This picture will help you in understanding the 3-views of the image.

It is a triangle. It is shown in 3 different views.  1^st one is the back view, 2^nd view is the side view of the triangle and 3^rd one is the TOP view of the Triangle.
