Animation

Question 1

What is animation?

Answer 1

Animation is the apparent movement of an object.
It is the result of a series of graphics or frames presented in rapid succession (to give the illusion of movement).

Animations often direct the attention of the user to an area of the screen or an interesting feature.
They are usually started automatically when a frame is viewed or by the user clicking a button.

Question 2

What are some common file formats for animation?

Answer 2

SWF (ShockWave Flash object)

Animated GIF (Graphics Interchange Format)

MOV (Movie)

HTML 5

Question 3

What are two types of Animation?

Answer 3

2D Animation and 3D Animation

Question 4

What are two main types of Tweens?

Answer 4

Motion Tween
This is where one object moves from one place on the screen to another in a typical smooth animation.

Shape Tween
This is where one object changes its shape from one object to a different object.

Question 5

What is Cel animation (stop motion, claymation)?

Answer 5

A cel, short for celluloid, is a transparent sheet on which objects are drawn or painted for traditional, hand-drawn animation.

Each frame of animation is drawn onto paper, then transferred onto a cel. Colour is then added on the reverse of the cel. Layers are built up to create dimension. The cels are then photographed onto film by a rostrum camera.

Question 6

What is a Path animation?

Answer 6

A path animation controls the position and rotation of an object along a curve. An object must first be attached to the curve for it to become a path curve.

Question 7

What is a NURBS curve?

Answer 7

A NURBS curve is a curve that cannot be designated as a motion path.

Non-Uniform RationalBasis Spline(NURBS) is a mathematical model commonly used incomputer graphicsfor generating and representing curves and surfaces.

Question 8

What is Morphing?

Answer 8

Morphing is a special effect in animations that changes one image or shape into another through a seamless transition.
Most often it is used to depict one person turning into another person or object

Question 9

Define Morphing.

Answer 9

Morphing is a term for transforming one image to another. The object is changed and modified to look into another object. Such as changing a square into a circle.

Question 10

What is a transition?

Answer 10

• a transtion is change from one scene to the next scene like in movies or powerpoints.
• a transition also occurs when an element changes from one state to another, and the browser fills in that state change with a sequence of in-between frames. It has a beginning and an end state.

Question 11

What is a Behavior animation?

Answer 11

Behavioral animation is a type of procedural animation.
Which is a type of computer animation or artificial intelligence.

In behavioral animation an autonomous character determines its own actions, at least to a certain extent.

This gives the character some ability to improvise, and frees the animator from the need to specify each detail of every character’s motion.

Question 12

What is Tweening?

Answer 12

Tweening is a very simple concept in computer graphics that has very powerful and visually impressive applications.

In tweening, key frames are provided at set interval along a timeline, and “in-between” frames are calculated by the computer to make a smooth looking animation.

It adds the extra frames in for you to create a smooth animation. Tweening has applications in both computer animation and hand drawn animation .

Question 13

Which techniques are required for Morphing?

Answer 13

Morphing in 3D animations uses the following techniques:

- Morph target animation, Per-vertex animation, Shape interpolation, and Blend shapes

Question 14

Define Morphing.

Answer 14

Morphing is a term for transforming one image to another.

Question 15

What is Virtual Reality?

Answer 15

Virtual Reality is a combination of both the physical world we live in, and a virtual world generated by computer technology, in particular, 3D animation

Question 16

What is a Virtual Reality Walk through?

Answer 16

A virtual tour (walkthrough) is a simulation of an existing location, usually composed of a sequence of videos or still images

Question 17

What is “Looping” in a 2D Animation?

Answer 17

An animation loop is the repetition of part of the animation

For example, an animator can animate a clock pendulum swinging from one side to the other just once, then repeat the animated portion using animation softwares instead of repeating his work manually

Question 18

What is a 3D Animation?

Answer 18

3D Animations are objects that appear in a three-dimensional space.
They can be rotated and moved like real objects.

Question 19

What is 3D Modelling?

Answer 19

3D modeling is the process of developing a mathematical representation of any three-dimensional surface of an object (either inanimate or living) via specialised software

Question 20

What is a 3D Wireframe?

Answer 20

A wire-frame model is a visual presentation of a 3-dimensional (3D) or physical object used in 3D computer graphics. Wire framing is much quicker when rendering and viewing. It helps a computer function faster.

It is created by specifying each edge of the physical object where two mathematically continuous smooth surfaces meet, or by connecting an object’s constituent vertices using straight lines or curve.

Question 21

What is Rendering?

Answer 21

Renderingis the final process of creating the actual 2D or 3D image or animation from the prepared scene.

Question 22

What are different rendering methods?

Answer 22

Wireframe rendering
Polygon-based rendering
Scanline rendering
Ray tracing
Radiosity

Question 23

What is 3D Motion Capture

Answer 23

Motion Captureisthe process or technique of recording patterns of movement digitally, especially the recording of an actor’s movements for the purpose of animating a digital character in a film or computer game

Question 24

What is a Virtual Reality simulation?

Answer 24

A simulation is the imitation of the operation of a real-world process or system over time

A flight simulator is a virtual reality system capable of simulating the environment of a flying machine for a pilot

Question 25

What is a navigable scene in Virtual Reality?

Answer 25

Navigable scenes 360-degree VR is an audiovisual simulation of an altered, augmented or substituted environment that surrounds the user, allowing them to look around them in all directions, just as they can in real life.
