Dec 11, 2019 · History of Computer Graphics. Computer Graphics (CG) was first developed as a visualization tool. Computer graphics were basically introduced for scientists and engineers in government and corporate research centers, i.e., Bell Labs and Boeing in the 1950s.
The field of computer graphics is a broad and diverse field that exists cross section between computer science and design. It is interested in the entire process of creating computer generated imagery, from creating digital three-dimensional models, to the process of texturing, rendering, and lighting those models, to the digital display of those renderings on a screen.

Development is associated with fields such as engineering and architecture. While most developers face similar difficulties and use similar methodologies in their applications. The lack of a unique solution is one of the main features of most design problems. Therefore, the developer must analyze and then change a possible project, probably several times, to try to find a better solution. In this iterative process, computer graphics has become an essential element. For example, consider how computer graphics could hit the electronic circuit layout. The programmer sits with a graphics input device, such as the mouse, at a workstation where he can mark the positions on the screen. The initial display screen may consist of different elements to be used in the circuit and an empty area where the circuit is installed. The developer will then pick and transfer the desired elements and attach the elements to the model with the input device. In order to create this first model, the system u...
By using computer graphics, the interface between humans and machines has been dramatically altered. Take into account the digital office. The figures in this book have been generated by a single interface. Instead of a desk with a typewriter, a secretary sits at a workstation. The client has a pointing system like a joystick to interact with the workstation. There are several icons describing the different operations that can be performed by the secretary. For example, if you point out and click on a mailbox icon, any electronic mail messages can be shown on your screen. The client should dispose of unwanted emails by an icon of a paper box, whereas a cabinet icon can be used to save letters or other documents. Our circuit design framework will include a similar graphical interface. We see these interfaces as obvious uses of computer graphics in the context of this book. The images, however, are the secondary elements of the project, from the viewpoint of the secretary with the use...
Computer graphics are very often used for the design, modification, and development of different machine parts and the whole machine, mainly due to the accuracy and clearness obtained from this drawing for the sake of the secure manufacturer of the machine with this drawing.
The need for visualizationtoday has increased dramatically and many advance technologies will see the need for visualization. Data visualization helps us gain insights into the information to analyze and study the compatibility of the systems that we have around us.
Computer-generated models are extremely useful for the teaching, comprehension, and learning of a large number of concepts and fundamentals. Several educational models can be developed with computer graphics, through which more student interest in the topic may be generated.
Most of its offerings were used in the film and gaming industries via computer graphics. For film, TV shows, music video animated cartoon movies and creation. Computer graphics help to provide these functions effectively in the gaming industry, where concentration and interactivity are the main players.
To prepare reports or to summarize the accounting, numerical, political, mathematical, science and management reports, research reports and also the development of bar graphs, time chart pie diagrams, etc.
We can create fine and commercial art through computer graphics which include packages of animation and painting. These packages provide the facility to model the shapes of objects and to define the movement of an item.
Specialized training methods like simulators may be used to train candidates so that they can be understood with better understanding over a short period of time. It is simple and very useful to build training modules with computer graphics.
Specific types of photos or photographs need to be edited to be used at various locations. One of the many techniques of computer graphics is to transform existing images into optimized ones to enhance their understanding.

- Summary of The Pros and Cons
If you’ve ever taken or downloaded a digital photo, you’re already familiar with bitmap images, even if you weren’t aware that that’s what digital photos are. A bitmap represents an image by treating the image area as a rectangle, and dividing up the rectangle into a two-dimensional array of tiny pixels. For example, an image produced by a high-resolution phone camera may have dimensions of 4128 pixels horizontally and 3096 pixels vertically, requiring 4128×3096 = 12,780,288 pixels for the entire image. (Bitmap images usually involve large numbers of pixels, but computers are really good at handling large numbers of items!) Each pixel specifies a single color value for the image at that point. The resulting image is displayed simply by copying (“blitting”) the array of pixels to the screen, with each pixel showing its defined color. Some of the smallest bitmap images you’ll see are the icons used for programs and other items in computer user interfaces. The size of these bitmaps can...
The alternative way of producing a computer image is to create a list of instructions describing how to draw the image, then store that list as the image file. When the file is opened, the computer interprets each instruction and redraws the complete image, usually as a bitmap for display purposes. This process is called rasterization. This may seem to be an unnecessarily complex way to create a computer image. Wouldn’t it just be simpler to stick to bitmap images for everything? Well, it probably wouldn’t be a good idea to try to store a photo of your dog as a vector image, but it turns out that there are some cases where vector images are preferable to bitmap images. Part of the skill set of a digital artist is knowing which cases are best suited to vector images, and which to bitmaps. There are many vector drawing standards, and many of those are proprietary (e.g., AI, CDR). One open vector drawing standard that’s becoming increasingly popular is SVG(Scalable Vector Graphics). Yo...
It’s often necessary to convert a vector image into a bitmap image, and, less frequently, to convert a bitmap image into a vector image. Conversion of vector images to bitmaps occurs all the time, every time you want to view the content of a vector image. When you open a vector image, the computer reads the instructions in the file, and draws the shapes into a temporary bitmap that it displays for you. Converting bitmaps to vector images requires special software. The process is usually called “Tracing”. Years ago, you had to buy tracing software separately, but now most vector drawing software includes built-in tracing capabilities. As the name suggests, tracing software works by “drawing around” the edges of the bitmap, so that it creates shapes and lines representing the image. The result of the operation is that the software generates a set of mathematical curves that define the vector image.
There are situations where bitmap images are preferable to vector images, and vice versa. Here’s a summary of the pros and cons of each type. Bitmap Advantages: 1. Complex scenes can be depicted as easily as simple scenes. 2. Significant compression is usually possible, at the expense of loss of quality. 3. Rendering is computationally easy; requires minimal computing power. Disadvantages: 1. Size: Files tend to be large. 2. Not scalable: attempting to magnify an image causes degradation. Vector Advantages: 1. Compact: Files tend to be small. 2. Scalable: images can be displayed at any resolution without degradation. Disadvantages: 1. Complex scenes are difficult to encode, which tends to create very large files. 2. Rendering is computationally intensive; requires significant computing power.
