Use the screen draw tools of Presentation Assistant to write or draw freely on computer screen in presentation, so the interpretation or demonstration can be clearer. Sketchpad; multi-touch, multi-user, non-destructive drawing application written in HTML5. Wacom tablets provide unparalleled quality and usability, allowing artists to create with digital/computer drawing pads and tablets. A graphics program that enables you to draw pictures on the display screen which are represented as bit maps (bit-mapped graphics). In contrast, draw programs use vector graphics (object-oriented images), which scale better. Draw.io is free online diagram software for making flowcharts, process diagrams, org charts, UML, ER and network diagrams. How to Draw a Computer, Tower, Keyboard, Screen, Mouse. This is going to be a real simple tutorial. I am going to switch it up again by submitting a tutorial on how to draw a computer, mouse, keyboard. An Introduction to Computer Programming. Logo and Java are used, along with art and games to introduce the subject.Computer graphics - Wikipedia, the free encyclopedia. Computer graphics are pictures and movies created using computers . It is a vast and recent area in computer science. The phrase was coined by computer graphics researchers Verne Hudson and William Fetter of Boeing in 1. It is often abbreviated as CG, though sometimes erroneously referred to as CGI. Important topics in computer graphics include user interface design, sprite graphics, vector graphics, 3. SketchUp is 3D modeling software that's easy to learn and incredibly fun to use. Create powerful parametric profiles to draw walls, fences, rails, ladders, stairs, roads: almost anything you can imagine, at light speed. Like to draw really good pictures on the computer. D modeling, shaders, GPU design, and computer vision, among others. The overall methodology depends heavily on the underlying sciences of geometry, optics, and physics. Computer graphics is responsible for displaying art and image data effectively and meaningfully to the user, and processing image data received from the physical world. The interaction and understanding of computers and interpretation of data has been made easier because of computer graphics. Computer graphic development has had a significant impact on many types of media and has revolutionized animation, movies, advertising, video games, and graphic design generally. Overview. Computer imagery is found on television, in newspapers, for example in weather reports, or for example in all kinds of medical investigation and surgical procedures. A well- constructed graph can present complex statistics in a form that is easier to understand and interpret. Computer generated imagery can be categorized into several different types: two dimensional (2. D), three dimensional (3. D), and animated graphics. As technology has improved, 3. D computer graphics have become more common, but 2. D computer graphics are still widely used. Computer graphics has emerged as a sub- field of computer science which studies methods for digitally synthesizing and manipulating visual content. Over the past decade, other specialized fields have been developed like information visualization, and scientific visualization more concerned with . Screens could display art since the Lumiere brothers' use of mattes to create special effects for the earliest films dating from 1. The first cathode ray tube, the Braun tube, was invented in 1. Nevertheless, computer graphics remained relatively unknown as a discipline until the 1. World War II period - during which time, the discipline emerged from a combination of both pure university and laboratory academic research into more advanced computers and the United States military's further development of technologies like radar, advanced aviation, and rocketry developed during the war. New kinds of displays were needed to process the wealth of information resulting from such projects, leading to the development of computer graphics as a discipline. SAGE Sector Control Room. Early projects like the Whirlwind and SAGE Projects introduced the CRT as a viable display and interaction interface and introduced the light pen as an input device. Ross of the Whirlwind SAGE system performed a personal experiment in 1. One of the first interactive video games to feature recognizable, interactive graphics . Ross innovated again while working at MIT on transforming mathematic statements into computer generated machine tool vectors, and took the opportunity to create a display scope image of a Disneycartoon character. This began the decades- long transformation of the southern San Francisco Bay Area into the world's leading computer technology hub - now known as Silicon Valley. The field of computer graphics developed with the emergence of computer graphics hardware. Further advances in computing led to greater advancements in interactive computer graphics. In 1. 95. 9, the TX- 2 computer was developed at MIT's Lincoln Laboratory. The TX- 2 integrated a number of new man- machine interfaces. A light pen could be used to draw sketches on the computer using Ivan Sutherland's revolutionary Sketchpad software. The light pen itself had a small photoelectric cell in its tip. This cell emitted an electronic pulse whenever it was placed in front of a computer screen and the screen's electron gun fired directly at it. By simply timing the electronic pulse with the current location of the electron gun, it was easy to pinpoint exactly where the pen was on the screen at any given moment. Once that was determined, the computer could then draw a cursor at that location. Sutherland seemed to find the perfect solution for many of the graphics problems he faced. Even today, many standards of computer graphics interfaces got their start with this early Sketchpad program. One example of this is in drawing constraints. If one wants to draw a square for example, they do not have to worry about drawing four lines perfectly to form the edges of the box. One can simply specify that they want to draw a box, and then specify the location and size of the box. The software will then construct a perfect box, with the right dimensions and at the right location. Another example is that Sutherland's software modeled objects - not just a picture of objects. In other words, with a model of a car, one could change the size of the tires without affecting the rest of the car. It could stretch the body of car without deforming the tires. The phrase . Written for the DECPDP- 1, Spacewar was an instant success and copies started flowing to other PDP- 1 owners and eventually DEC got a copy. The sales force picked up on this quickly enough and when installing new units, would run the . Zajac, a scientist at Bell Telephone Laboratory (BTL), created a film called . He created the animation on an IBM 7. Also at BTL, Ken Knowlton, Frank Sinden and Michael Noll started working in the computer graphics field. Sinden created a film called Force, Mass and Motion illustrating Newton's laws of motion in operation. Around the same time, other scientists were creating computer graphics to illustrate their research. At Lawrence Radiation Laboratory, Nelson Max created the films Flow of a Viscous Fluid and Propagation of Shock Waves in a Solid Form. Boeing Aircraft created a film called Vibration of an Aircraft. Also sometime in the early 1. Pierre B. These curves would form the foundation for much curve- modeling work in the field, as curves - unlike polygons - are mathematically complex entities to draw and model well. It was not long before major corporations started taking an interest in computer graphics. TRW, Lockheed- Georgia, General Electric and Sperry Rand are among the many companies that were getting started in computer graphics by the mid- 1. IBM was quick to respond to this interest by releasing the IBM 2. Ralph Baer, a supervising engineer at Sanders Associates, came up with a home video game in 1. Magnavox and called the Odyssey. While very simplistic, and requiring fairly inexpensive electronic parts, it allowed the player to move points of light around on a screen. It was the first consumer computer graphics product. Evans was director of engineering at Bendix Corporation's computer division from 1. Berkeley. There he continued his interest in computers and how they interfaced with people. In 1. 96. 6, the University of Utah recruited Evans to form a computer science program, and computer graphics quickly became his primary interest. This new department would become the world's primary research center for computer graphics. Also in 1. 96. 6, Ivan Sutherland continued to innovate at MIT when he invented the first computer controlled head- mounted display (HMD). Called the Sword of Damocles because of the hardware required for support, it displayed two separate wireframe images, one for each eye. This allowed the viewer to see the computer scene in stereoscopic 3. D. After receiving his Ph. D. In 1. 96. 7 Sutherland was recruited by Evans to join the computer science program at the University of Utah - a development which would turn that department into one of the most important research centers in graphics for nearly a decade thereafter, eventually producing some of the most important pioneers in the field. There Sutherland perfected his HMD; twenty years later, NASA would re- discover his techniques in their virtual reality research. At Utah, Sutherland and Evans were highly sought after consultants by large companies, but they were frustrated at the lack of graphics hardware available at the time so they started formulating a plan to start their own company. In 1. 96. 8, Arthur Appel described the first algorithm for what would eventually become known as ray casting - a basis point for almost all of modern 3. D graphics, as well as the later pursuit of photorealism in graphics. In 1. 96. 9, the ACM initiated A Special Interest Group on Graphics (SIGGRAPH) which organizes conferences, graphics standards, and publications within the field of computer graphics. By 1. 97. 3, the first annual SIGGRAPH conference was held, which has become one of the focuses of the organization. SIGGRAPH has grown in size and importance as the field of computer graphics has expanded over time. Many of the most important early breakthroughs in the transformation of graphics from utilitarian to realistic occurred at the University of Utah in the 1. Ivan Sutherland away from MIT. Sutherland's graphics class would contribute a number of significant pioneers to the field, including a student by the name of Edwin Catmull - a later founder of Pixar. Evans' and Sutherland's presence, UU was gaining quite a reputation as the place to be for computer graphics research so Catmull went there to learn 3. D animation. Catmull had just come from The Boeing Company and had been working on his degree in physics. Growing up on Disney, Catmull loved animation yet quickly discovered that he did not have the talent for drawing. Now Catmull (along with many others) saw computers as the natural progression of animation and they wanted to be part of the revolution. The first animation that Catmull saw was his own. He created an animation of his hand opening and closing. It became one of his goals to produce a feature- length motion picture using computer graphics. Khan Academy.
