| Question | Answer |
|---|---|
| pixel | a single point in a raster image |
| raster | A scanning pattern of parallel lines that form the display of an image projected on a cathode |
| Crt | Cathode Ray Tube |
| Lcd | liquid crystal display |
| Cones | cone |
| trichromatic vision | the condition of possessing three independent channels for conveying color information, derived from the three different cone types, red blue and green |
| spectrum | a band of seven colors obtained after white light is split. Red orange yellow green blue indigo violet. |
| image resolution | the frequency of pixels within a given area of a document, typically one inch |
| moniter resolution | the number of distinct pixels in each dimension that can be displayed |
| output resolution | The resolution of the device used for the final output of a digital file expressed as dots per inch (dpi) |
| temporal resolution | frames per second, fps |
| color resolution | the number of bits used to represent the color of a single pixel in a bitmapped image |
| rgb color | This additive colour model describes a pixel’s colour in terms of a Red, Green and Blue component |
| true color | 24 bit |
| bit depth | the number of bits used to store information about each pixel of an image |
| indexed color | reduced color mapping of 8 |
| clut – color look | up table |
| swatch | the colors you are using |
| hsl | hue, saturation, lightness |
| aliased | a jaggy edge |
| pixilated | single pixels are visible to the naked eye |
| anti-aliased | making a jaggy edge look smooth |
| banding | the resolution is not very high and the colors don’t blend, instead they appear in a row of bands |
| dithering | attempt to approximate a color from a mixture of other colors, in order to fix banding. |
| Resizing | changing the size of an image without deleting any information |
| Resampling | changing the size of an image while deleting information |
| Interpolation | increase image size without pixelating by using original pixel information |
| Selections | path, what you are working on |
| alpha channels | a portion of each pixel's data that is reserved for transparency information |
| image layers | transparencies lying on top of each other |
| asjustment layers | you can see through them but they don’t change anything actually below them. So you can apply an adjustment on a layer and it will become an adjustment layer |
| vector vs. bitmap. Vector illustration is object | oriented. Geometry based as apposed to pixel based. Lines are crisper and cleaner than bitmap lines. vector graphics are called resolution |
| Path | Line between two or more points. A Path itself is the skeleton of an object you are making, it is nothing, it doesn’t print. |
| anchor point | An exact location in space. In an open path, the starting and ending anchor points are called end points |
| Segment | a part of a line that is bounded to two anchor points |
| Bezier curves | vector curves. used to model smooth curves that can be scaled indefinitely. "Paths." |
| Direction lines | control a curve’s height and slope |
| Direction points | Edit by dragging the direction points |
| Strokes | appearance of line segments. A linear portion of the path and its characteristics. The outline around a shape. You can change its Width, color, style |
| Fills | the open area inside a closed path |
| Compound paths | consists of two or more paths that interact with each other |
| Shape modes | add, subtract, intersect, and exclude shapes |
| Pathfinders | pallet In illustrator used to combine paths, divide objects, subtract shapes, etc. |
| Animation | the rapid display of a sequence of images in order to create the illusion of movement |
| Kinetograph | designed for films to be viewed individually through the window of a cabinet housing its components |
| Persistence of vision | Because we see images a split second longer than they actually appear, a serious of pictures in sequence appear to be one continuous motion picture |
| Keyframe | a drawing that defines the starting and ending points of any smooth transition |
| Tweening | tweens can be used to change shape and size (morphing), position, rotation, color, and transparency |
| Cycles, loops, sprites | a short sequence is repeated several times to form a longer action |
| Exaggeration – to make an expression appear realistic in an animation you must over | exaggerate it |
| Squash & stretch | techniques to make things appear more real |
| Anticipation | viewers are prepared for the next movement and expect it before it actually occurs |
| Point of view | effects viewers feelings and impressions of the scene |
| Close | ups– add varietymake the viewer pay attention to what the director wants them to see |
| Zooming | Zooming in intensifies the action or emotion zooming out has a calming affect |
| Panning | feels as if the viewer’s head is turning with the camera |
| Cuts | the most common quick shifts of view |
| Fades | indicates that there has been a complete change in time… |
| Wipes | tell the viewer a change in location is happening |
| Ivan Sutherland | The father of computer graphics. As a graduate student at MIT he wrote Sketchpad as his doctoral thesis. |
| Winsor mckay | gertie the dinorsaur. One of the most influential films in the history of animated films, early 1900’s |
| Otto messmar | felix the cat |
| Felix the Cat | First animate character to have marketed merchandise, 1920’s |
| The Fleischer bros | koko the clown, betty boop, popeye, 1920’s |
| Walt Disney | steamboat willie (mickey mouse). First synchronized sountrack (mickey mousing), 1928. Snow white and the seve dwarfs. First full length animated film. Cost 1.5 mill to make and earned more than 1.5 billion, 1937 |
| Chuck jones | warner bros animator. Bugs bunny, daffy duck, elmer fudd, porky pig, pepe lepew… 1938. How the Grinch stole Christmas – 1960’s |
| Mel blanc | worked for warner bros as the voice of Bugs Bunny, Daffy Duck, Porky Pig, Sylvester the Cat, Tweety Bird, and hundreds of others |
| John lasseter | chief creative officer at Pixar and Walt Disney Animation Studios |
| Pixar | animation studio in emeryville, subsidiary of Disney. began in 1979 as the Graphics Group, part of the Computer Division of Lucasfilm |
| Tron | one of the first movies to make extensive use of any form of computer animation, and is celebrated as a milestone in the computer animation industry – 1982 |
| Toy story | 1995 first disney/pixar film to be made. First feature film to be made with computer generated imagery |
| 3d computer graphics | Modeling – a wireframe is made up of polygons in a virtual 3D space containing an x, y, and z axis |
| Wireframe | a visual presentation of a three dimensional or physical object used in 3D computer graphics |
| Polygon –used to compose images that are three | dimensional in appearance |
| Shading | a color, texture map, or pattern is added |
| Texture map | a method for adding detail, surface texture (a bitmap or raster image), or color to a computer |
| Rendering | the process of creating 2d image or animation from the 3d data you have created |
| Live action | animation done with real people or objects |
| Motion capture | White spots are attached to a skin |
| Virtual camera | A virtual camera system aims at controlling a camera or a set of cameras to display a view of a 3D virtual world. |
| Digital puppetry | the manipulation and performance of digitally animated 2D or 3D figures and objects in a virtual environment that are rendered in real |
