Pixillation animation

pixillation animation is like a human pupet. Using pictures to create a scene is basically what it is about. pictures in the media industry is known as frames. when doing this sort of technique shots are very important aswell as s stead pose of the character used for the sequence.
I found a nice piece of work which use this technique to produce a master piece.
example:



In computer graphics, pixelation (or pixellation in UK English) is an effect caused by displaying a bitmap or a section of a bitmap at such a large size that individual pixels, small single-colored square display elements that comprise the bitmap, are visible to the eye.
In the real-time of 3D computer graphics, pixelation can be a problem. Here, bitmaps are applied to polygons as textures. As a camera approaches a textured polygon, simplisticnearest neighbor texture filtering would simply zoom in on the bitmap, creating drastic pixelation. The most common solution is a technique called pixel interpolation that smoothly blends or interpolates the color of one pixel into the color of the next adjacent pixel at high levels of zoom. This creates a more organic, but also much blurrier image. There are a number of ways of doing this; see texture filtering for details.Early graphical applications such as video games ran at very lowresolutions with a small number of colors, and so had easily visible pixels. The resulting sharp edges gave curved objects and diagonal lines an unnatural appearance. However, when the number of available colors increased to 256, it was possible to gainfully employ antialiasing to smooth the appearance of low-resolution objects, not eliminating pixelation but making it less jarring to the eye. Higher resolutions would soon make this type of pixelation all but invisible on the screen, but pixelation is still visible if a low-resolution image is printed on paper.
Pixelation is a problem unique to bitmaps. Alternatives such as vector graphics or purely geometric polygon models can scale to any level of detail. This is one reason vector graphics are popular for printing — most modern computer monitors have a resolution of about 100 dots per inch, and at 300 dots per inch printed documents have about 9 times as many pixels per unit of area as a screen. Another solution sometimes used is algorithmic textures, textures such as fractals that can be generated on-the-fly at arbitrary levels of detail.


drawn animation




Drawn on animation is an animation technique where footage is produced by creating the images directly on filmstock, as opposed to cel animation where the images are created on separate sheets of plastic or paper before being photographed onto filmstock.
The most famous practictioner of drawn on film animation is Norman McLaren, who produced numerous animated films using this method, including Begone Dull Care.
example of drawn animation:


There are eight stages to become a good animator:
-Cretaing the character
-Details of the character (height/weight)
-Turnarounds
-Movement sketches
-off model/on model
-advanced aniamtin drawing
-background drawing
-colouring and props

Frame Rate
The term Frame rate applies equally well to computer graphics, videos and motion systems. Frames is often shown per second. When adding animation to an application the frame rate if it too high it can lead to processor problems especially when usind autoscript to create an animation.

ClayMation

ClayMation
Producing a stop-motion animation using clay is extremely laborious. Normal film runs at 24 fps. With the standard practice of exposing 2 frames for each shot, 12 changes are usually made for one second of film movement. For a 30-minute movie, there would be approximately 21,600 stops to change the figures for the frames. For a full-length (90-minute) movie, there would be approximately 64,800 stops, and possibly far more if parts were shot with single frame exposed for each shot.

Clay animation can take several forms:

Freeform clay animation is an informal term to the process in which the shape of the clay changes as the animation goes on such as in the work of Ivan Stang's animated films which are very good indeed.

Strata-cut is an animation which a long breadlike loaf of clay internally packed tight and loaded with varying imagery is sliced into thin sheets with the camera taking a frame of the end of the loaf for each cut. Eventually showing the movement of the internal images. Pioneered in both clay and blocks of wax by German animator called Oskar Fischinger during the 1920s and '30s era. The technique was revivied and highly rated in the mid-'90s by David Daniels who is an associate of Will Vinton in his 16-minute short film Buzz Box.

Another clay-animation technique that involves one that blurs the distinction between stop motion and traditional flat animation is called clay painting. Clay is placed on a flat surface and moved like wet oil paints to produce any style of images but with a clay look to them.

The Phi Phenomenon is a perpetual illuision in which a disembodied perception of motion is produced by a succession of still images. In discussion of the perception of film and video it is often confused with beta movement, but it is a distinct phenomenon not directly involved in the perception of motion pictures.


An example of
a beta movement
zeotrope is one example of a Phi Phenomenon.
Cut Out animation
This is an example of Cut Out animation that i have found on youtube.com.


Cut out animation is an animation technique that is used things like paper, stiff fabric or photographs, the characters and backrounds are made from these materials.

One of the earliest cut out animation was made by Quirino Cristiani located in argentina. Today Cut out animation has been upgraded by technology. now people use by computers using scanned images or vector graphics to continue this method.

Vector graphics is using Geomatrical primitives like points, lines , shapes or polygons, which come from mathmatical equations.

Famous artists who use this technique are Noburu Ofuji who created the Thieves of Baghdad, The Adventures of Prince Achmed by Lotte Reiniger, L'armata Brancaleone an italian film animated by Emanuele Luzatti and theres many more.

Cut out animation is simpler then drawn animation. This type of animation only consists of using different shapes and sizes made from all kinds materials, which is easier then drawn animation which has to have many frames and very detailed drawing.

object animation

Object animation is a form of stop motion animation

that involves the animated movements of any non-
drawn objects such as toys, blocks, dolls, etc.

types of stop animation are:

Cravendale Milk Last Glass
Game Over
Coinstar
E4 Channel Ident

here is a video of a project we done as a class:

zeotropes

A zoetrope is a tool consisting of a cylinder with slits cut vertically in the sides. Beneath the slits, on the inner surface of the cylinder, is a band which has either individual frames from a video/film or images from a set of sequenced drawings or photographs. As the cylinder spins, the user looks through the slits at the pictures on the opposite side of the cylinder's interior. The scanning of the slits keeps the pictures from simply blurring together, so that the user sees a rapid succession of images producing the illusion of motion, the equivalent of a motion picture. Cylindrical zoetropes have the property of causing the images to appear thinner than their actual sizes when viewed in motion through the slits.zoetrope-main.jpg
