Keeping your hands germ-free, through the use of soaps. http://survisani.guru/9BkTYEsvthiadI1jrPqWK0nB44sbTgOMSCkBMzuTb12z4dpW http://survisani.guru/yhmkdkAvRH-bXUxLRP2Hlc_Mbu-iWSCVoC9hhlNds2Mof50r One of these students was Edwin Catmull. 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 computer animation that Catmull saw was his own. He created an animation of his hand opening and closing. He also pioneered texture mapping to paint textures on three-dimensional models in 1974, now considered one of the fundamental techniques in 3D modeling. It became one of his goals to produce a feature-length motion picture using computer graphics b a goal he would achieve two decades later after his founding role in Pixar. In the same class, Fred Parke created an animation of his wife's face. The two animations were included in the 1976 feature film Futureworld. As the UU computer graphics laboratory was attracting people from all over, John Warnock was another of those early pioneers; he would later found Adobe Systems and create a revolution in the publishing world with his PostScript page description language, and Adobe would go on later to create the industry standard photo editing software in Adobe Photoshop and a prominent movie industry special effects program in Adobe After Effects. James Clark was also there; he would later found Silicon Graphics, a maker of advanced rendering systems that would dominate the field of high-end graphics until the early 1990's. A major advance in 3D computer graphics was created at UU by these early pioneers b hidden surface determination. In order to draw a representation of a 3D object on the screen, the computer must determine which surfaces are "behind" the object from the viewer's perspective, and thus should be "hidden" when the computer creates (or renders) the image. The 3D Core Graphics System (or Core) was the first graphical standard to be developed. A group of 25 experts of the ACM Special Interest Group SIGGRAPH developed this "conceptual framework". The specifications were published in 1977, and it became a foundation for many future developments in the field. Also in the 1970s, Henri Gouraud, Jim Blinn and Bui Tuong Phong contributed to the foundations of shading in CGI via the development of the Gouraud shading and Blinn-Phong shading models, allowing graphics to move beyond a "flat" look to a look more accurately portraying depth. Jim Blinn also innovated further in 1978 by introducing bump mapping, a technique for simulating uneven surfaces, and the predecessor to many more advanced kinds of mapping used today. The modern videogame arcade as is known today was birthed in the 1970s, with the first arcade games using real-time 2D sprite graphics. Pong in 1972 was one of the first hit arcade cabinet games. Speed Race in 1974 featured sprites moving along a vertically scrolling road. Gun Fight in 1975 featured human-looking animated characters, while Space Invaders in 1978 featured a large number of animated figures on screen; both used a specialized barrel shifter circuit made from discrete chips to help their Intel 8080 microprocessor animate their framebuffer graphics ------------------------------ End of alt.music.moxy-fruvous digest V14 #3835 **********************************************
