Q

what is an index and where is it stored

A

contains an index contains an alphabetical list of the words, and on which page it was found, and where on the page it was found

Index is stored in a really big database
Looks sort of like this:
keyword Index: Page and position within page 
20 africa 2 (title) 7 (… 19 27 30
3 (body, 2nd word, 8th word)

Q

before 1990, how did search engines work

Q

1994 how did search engines work

A

some software allowed the user to submit pages they wanted included in the index
the indexes that were built began to include all the data on the webpage (not just tile and URL)

Q

1995 how did search engines work

A

Unlimited bandwidth for the first time
more intuitive searches (just by words not necessarily by categories)
more advanced searching techniques like Ca* would return Canada, Cats etc
Add url to index and it gets added within 24 hours
However, results were still returned randomly with basic techniques

Q

*** 1996 ** what happened in search engines and who did it

A

Larry Page and Sergey Brin came up with “BackRub” (Later called page rank) algorithm to have less random search returns
Based on data that “analyzed the relationships between websites would produce better ranking of results than existing techniques which ranked results according to the number of times the search term appeared on a page”

Q

How does Google’s page rank algorithm work

A

evaluates 2 factors:
How many links are there to a web page
◦ What is the quality of the linking sites (although a high
ranked page with LOTS of links on it may pass you less
because it is spread too thinly)

The algorithm gives each webpage returned from the keyword search a weight between 0 and 1

The higher the weight given to the page, the
more likely it is that this page will be
displayed first to you.

The more sites that link to you, the higher up you go on the ranking

also if a highly-ranked site links to your site, then you also get a higher ranking

each pixel gets assigned a colour

54
Q

what is cel animation

A

a cel is a transparent sheet on which a character, scene, etc. is drawn and which constitutes one frame

traditional, hand-drawn animation frame by frame animation

To simplify, one background is drawn and then the
item that will move is drawn on a clear sheet of
plastic (a cel), one drawing for each frame.
 When moving to the next scene, just change the
background

55
Q

what is path based animation

allows animators to see adjacent frames at once

57
Q

what is a cel

A

A transparent sheet on which a character or scene is drawn and which constitutes one frame

Creating the intermediate frames based on the starting keyframe and ending keyframe.
a group of computer-generated frames to indicate motion

59

what is a keyframe

A

the starting point of a smooth transition of a series of frames

60
Q

what is a cinemagraph

A

an image that combines still photography with video to create a pic that contains a small moving element while the rest is frozen

61
Q

what are the 5 kinds of animation

A

2d(path based), 3d, stop motion, traditional animation, computer animation and motion graphics (which uses path based animation behind the scenes- what we did)

A

2d and motion graphics

64
Q

3d animation involves 3 steps:

A
  • Modelling
  • Rendering
  • Animation
65
Q

how does path based animation work

A

Pick:
◦ a starting point for an object, (start frame)
◦ an ending point for an object (end frame)
◦ a path for the object to follow
computer tweens all the frames in between (tweening = computer generating the rest)

66
Q

what features does path based animation have

A
  • looping
  • transition (fade in/out)
  • Repetitions (allows user to pick how many times the animation repeats
  • Setting the frames per second
67
Q

if your animation is too slow….

A

to slow: speed up animation by reducing the number of frames ( pull out every other frame) OR Increase the frame rate

68
Q

if your animation is too fast

A

too fast: slow down animation by adding more frames (keep the frame rate the same and increase the num of frames between the keyframes to stretch out animation) OR Lower frame rate (keep number of frames the same but stretches out the movie)

69
Q

what is drawing on ones

A

animation - drawing on each frame

70
Q

what is drawing on twos

A

animation- drawing on every other frame - better and smoother for slower animations

71
Q

what is follow through in terms of animation

A

some part of the body will move back and forth as the main entity moves. ex moving a pot with a flower, the flower will move from one end to another

72
Q

what is anticipation in terms of animation

A

some part of the body will move back and forth as the main entity moves. ex moving a pot with a flower, the flower will move from one end to another

73
Q

what is squash and stretch in terms of animation

A

to emphasize speed and mass (squishy = flatter when it lands) this can also emphasize facial expressions

74
Q

what is rotoscoping

A

is a type of animation that uses pencil drawing on top of a live-action video to make it look like a drawn animation. This feature was used in the music video for “Take On Me” by A-ha. SPELLING MATTERS - BE CAREFUL!

75
Q

what is an example of ease in terms of animation

A

In an animation, a spaceship takes off slowly and accelerates to a faster velocity over several seconds. This is an example of which animation effect?

76
Q

what are three different file types for animation

A

.gif
.swf
.mp4

77
Q

what is the file size of an animation affected by

A

the size of the gif (frame dimensions)

number of colours, number of frames

78
Q

how many colours do gifs allow

A

256

79
Q

do gifs require plug ins

A

no
No Plug-ins Required: Animated GIFs require no plug-ins, and
the authoring tools to create them are often free and easy to learn.

80
Q

do gifs have sound

A

 No Sound: If you need sound in addition to motion, you cannot
use an animated GIF by itself. Instead, you may want to consider
other animation alternatives, such as Flash, or even video

81
Q

when was FLASH launched

A

1996 by Macromedia

82
Q

what is flash

A

Flash Player is a free client application that works with popular
Web browsers to play the animation
a multimedia authoring and playback system

83
Q

does flash support vector graphics

A

yes

84
Q

who killed flash

A

apple because they didnt alow flash on apple devices

85
Q

what are the three kinds of tweens

A

motion tween - aniates symbols only - creates initial tween and goes to a frame and moves the object and that frame becomes a keyframe
cant morph - only position and rotation
Shape tween - works with non symbol shapes and vector graphics only - can morph shapes
classic tween - animates symbols only - need to manually create all keyframes and then connect with a tween - cannot morph

86
Q

what is a motion guide

A

lets you animate an object along a path that you draw yourself only works on symbols

87
Q

what is the frame rate you need on computers for animation
