Brief history of Animation

Brief history of Animation

ANIMATION
Animation refers to the creation of a sequence of images—drawn, painted, or produced by other artistic methods—that change over time to portray the illusion of motion. Before the invention of film, humans depicted motion in static art as far back as the Paleolithic period. In the 1st century, several devices successfully depicted motion in animated images

EARLY ANIMATION DEVICES:
Numerous devices that successfully displayed animated images were introduced well before the advent of the motion picture. These devices were used to entertain, amaze, and sometimes even frighten people. The majority of these devices didn't project their images, and accordingly could only be viewed by a single person at any one time. For this reason they were considered toys rather than devices for a large scale entertainment industry like later animation. Many of these devices are still built by and for film students learning the basic principles of animation.

The magic lantern (1650)
The magic lantern is an early predecessor of the modern day projector. It consisted of a translucent oil painting, a simple lens and a candle or oil lamp. In a darkened room, the image would appear projected onto an adjacent flat surface. It was often used to project demonic, frightening images in a phantasmagoria that convinced people they were witnessing the supernatural. Some slides for the lanterns contained moving parts, which makes the magic lantern the earliest known example of projected animation. The origin of the magic lantern is debated, but in the 15th century the Venetian inventor Giovanni Fontana published an illustration of a device that projected the image of a demon in his Liber Instrumentorum. The earliest known actual magic lanterns are usually credited to Christiaan Huygens or Athanasius Kircher.[7][8]

Thaumatrope (1824)
A thaumatrope is a simple toy that was popular in the 19th century. It is a small disk with different pictures on each side, such as a bird and a cage, and is attached to two pieces of string. When the strings are twirled quickly between the fingers, the pictures appear to combine into a single image. This demonstrates the persistence of vision, the fact that the perception of an object by the eyes and brain continues for a small fraction of a second after the view is blocked or the object is removed. The invention of the device is often credited to Sir John Herschel, but John Ayrton Paris popularized it in 1824 when he demonstrated it to the Royal College of Physicians.[9]

Phenakistoscope (1831)

The phenakistoscope was an early animation device.[10] It was invented in 1831, simultaneously by the Belgian Joseph Plateau and the Austrian Simon von Stampfer. It consists of a disk with a series of images, drawn on radii evenly spaced around the center of the disk. Slots are cut out of the disk on the same radii as the drawings, but at a different distance from the center. The device would be placed in front of a mirror and spun. As the phenakistoscope spins, a viewer looks through the slots at the reflection of the drawings, are momentarily visible when a slot passes by the viewer's eye.[11] This created the illusion of animation.

Zoetrope (1834)
The zoetrope concept was suggested in 1834 by William George Horner, and from the 1860s marketed as the zoetrope. It operates on the same principle as the phenakistoscope. It was a cylindrical spinning device with several frames of animation printed on a paper strip placed around the interior circumference. The observer looks through vertical slits around the sides to view the moving images on the opposite side as the cylinder spins. As it spins, the material between the viewing slits moves in the opposite direction of the images on the other side and in doing so serves as a rudimentary shutter. The zoetrope had several advantages over the basic phenakistoscope. It did not require the use of a mirror to view the illusion, and because of its cylindrical shape it could be viewed by several people at once.[12]

In ancient China, people used a device that one 20th century historian categorized as "a variety of zoetrope."[5] It had a series of translucent paper or mica panels and was operated by being hung over a lamp so that vanes at the top would cause it to rotate as heated air rose from the lamp. It has been claimed that this rotation, if it reached the ideal speed, caused the same illusion of animation as the later zoetrope, but because there was no shutter (the slits in a zoetrope) or other provision for intermittence, the effect was in fact simply a series of horizontally drifting figures, with no true animation.[13][14][15]

Flip book (1868)

John Barnes Linnett patented the first flip book in 1868 as the kineograph. A flip book is a small book with relatively springy pages, each having one in a series of animation images located near its unbound edge. The user bends all of the pages back, normally with the thumb, then by a gradual motion of the hand allows them to spring free one at a time. As with the phenakistoscope, zoetrope and praxinoscope, the illusion of motion is created by the apparent sudden replacement of each image by the next in the series, but unlike those other inventions no view-interrupting shutter or assembly of mirrors is required and no viewing device other than the user's hand is absolutely necessary. Early film animators cited flip books as their inspiration more often than the earlier devices, which did not reach as wide an audience.[16]

The older devices by their nature severely limit the number of images that can be included in a sequence without making the device very large or the images impractically small. The book format still imposes a physical limit, but many dozens of images of ample size can easily be accommodated. Inventors stretched even that limit with the mutoscope, patented in 1894 and sometimes still found in amusement arcades. It consists of a large circularly-bound flip book in a housing, with a viewing lens and a crank handle that drives a mechanism that slowly rotates the assembly of images past a catch, causing the pages to flip. A helical bound version, patented but not commercialized, made it theoretically possible for a mutoscope of reasonable size to match the running time of an entire reel of film.

Praxinoscope (1877)
The first known animated projection on a screen was created in France by Charles-Émile Reynaud, who was a French science teacher. Reynaud created the Praxinoscope in 1877 and the Théâtre Optique in December 1888. On 28 October 1892, he projected the first animation in public, Pauvre Pierrot, at the Musée Grévin in Paris. This film is also notable as the first known instance of film perforations being used. His films were not photographed, but drawn directly onto the transparent strip. In 1900, more than 500,000 people attended these screenings.

Burn fat in a Week

Burn fat in a Week
Follow this instructions and burn fat in a week...


Drink Mainly Water 
A sports or energy drink, fruit smoothie, or light beer — each serving contains about 100 calories. Yet these beverages don't satisfy you the way 100 calories of food does, so they're a waste. Other liquids may be high in sodium and carbohydrates, which trick your body into retaining water, puffing you out.
Water, on the other hand, has zero calories and carbs and little to no sodium, making it the perfect slim-down drink. And strangely, it actually helps flush out excess water weight as well as jump-starts your metabolism. If it's just too boring, add lemon wedges or mint leaves.

Do Cardio 30 Minutes a Day
Any workout that gets your heart rate up will burn calories. But you'll use more calories if you pick a cardio routine that engages multiple muscles simultaneously, says Wendy Larkin, personal-training manager at Crunch's Polk Street gym, in San Francisco.
Three to consider: spinning, cardio kickboxing, and boot-camp workouts. Half an hour of each torches 200 to 300 calories while toning up your arms, legs, and core so everything appears sleeker and tighter.
You'll burn even more calories per session if your workout incorporates interval training: alternating short bursts of intense cardio with slower activity. Experts aren't sure why it works, but trainers swear by it.

Drink Coffee an Hour Before Working Out 
This is the one exception to the stick-to-water-only rule: Just as a coffee run makes your morning at work more productive, a pre-exercise cup of java with a splash of skim milk (about 11 calories) or black (just 5 calories) will energize your workout, explains Dr. Klauer. "You'll burn more calories without realizing you're pushing yourself harder."

Have Nightly You-on-Top Sex 
Not that you needed an excuse to hook up with your guy every night, but the fact is, this position is a fat blaster. Being on top means you do the rocking, and the more active you are, the more calories you burn — up to 144 for 30 minutes.
Sex also pumps levels of feel-good neurotransmitters, endorphins, helping you ride out food cravings. Get on top in reverse-cowgirl (i.e., facing away from your guy) to give your thigh and butt muscles an extra push. 

Do 36 Push-Ups and Lunges Every Other Day
These gym-class staples will help sculpt muscle, so you'll sport a more streamlined appearance. Do three sets of 12 of each exercise every other day. "Push-ups target your upper body, while lunges work your butt, hips, and thighs," says Larkin. Quick tip: Make sure your back and legs remain in a straight line during your push-ups; it'll improve muscle tone. Also, you can build even more muscle with the lunges if you hold free weights in each hand while doing them.

Sleep 30 Minutes More a Night 
That extra half an hour, whether you sleep 5 hours or 8, can refresh you enough that you will make better food choices (in other words, no quick sugar fix for breakfast in search of energy) and won't feel lethargic and skip the gym, says registered dietician Esther Blum, author of Eat, Drink, and Be Gorgeous. More restful sleep (7 to 8 hours is best) also boosts your metabolism. And since your body builds muscle while you snooze, getting zzz's equals better muscle tone.

Make One Food Sacrifice 
Cutting out one indulgence — such as the chips you have with lunch or the chocolate dessert you eat after dinner — can subtract a few hundred calories from your diet, which translates into less flab, says Blum. "Your body won't even notice their absence."

Don't Let the Camera Add Pounds
Push your chin forward, hold your arms away from your body, and turn slightly sideways from the camera with one foot in front of the other.

GET THINNER IN HOURS
Really. These slenderizing effects may not be permanent, but they'll help you look hotter in your skinniest jeans on very short notice.

Eat Salmon for Lunch
It's packed with nutrients that build muscle tone and give your skin a healthy glow. Some nutritionists claim that consuming a portion (doesn't matter how it's cooked) may immediately make your face look a bit more contoured.

Stand Up Straight
Keeping your spine rigid and your shoulders back while sucking in your belly toward your spine gives you a slimmer, more streamlined middle.

Do Squats and Sit-Ups
Bodybuilders use this technique before competitions because it adds definition to muscle. Do three sets of 12 of each exercise to tighten your abs, butt, and legs temporarily.

Pop an Antigas Pill
Take one of these chewable tablets, sold over-the-counter at drugstores, to relieve bloating in your abdomen and break up gas bubbles in your digestive track, leaving you with a flatter tummy.

Personal Computers

Personal Computers
Personal Computer (PC), computer in the form of a desktop or laptop device designed for use by a single person. PCs function using a display monitor and a keyboard. Since their introduction in the 1980s, PCs have become powerful and extremely versatile tools that have revolutionized how people work, learn, communicate, and find entertainment. Many households in the United States now have PCs, thanks to affordable prices and software that has made PCs easy to use without special computer expertise. Personal computers are also a crucial component of information technology (IT) and play a key role in modern economies worldwide.

The usefulness and capabilities of personal computers can be greatly enhanced by connection to the Internet and World Wide Web, as well as to smaller networks that link to local computers or databases. Personal computers can also be used to access content stored on compact discs (CDs) or digital versatile discs (DVDs), and to transfer files to personal media devices and video players.
Personal computers are sometimes called microcomputers or micros. Powerful PCs designed for professional or technical use are known as work stations. Other names that reflect different roles for PCs include home computers and small-business computers. The PC is generally larger and more powerful than handheld computers, including personal digital assistants (PDAs) and gaming devices.
