What does CGI stand for?

  1. Computer Generated Imagery

  2. Computer Graphics Interface

  3. Computer-Aided Design

  4. Computer-Generated Images


Correct Option: A
Explanation:

CGI stands for Computer Generated Imagery, which refers to the use of computer graphics to create realistic images or animations.

Which of the following is not a common type of CGI animation?

  1. 3D animation

  2. 2D animation

  3. Motion capture

  4. Stop-motion animation


Correct Option: D
Explanation:

Stop-motion animation is a technique that involves physically moving objects frame-by-frame to create the illusion of movement, while 3D animation, 2D animation, and motion capture are all CGI animation techniques.

What is the primary software used for creating CGI animations?

  1. Adobe Photoshop

  2. Maya

  3. Microsoft Paint

  4. Blender


Correct Option: B
Explanation:

Maya is a popular software specifically designed for creating 3D animations and visual effects, while Adobe Photoshop is primarily used for image editing, Microsoft Paint is a basic drawing program, and Blender is an open-source 3D creation suite.

Which of the following is a key element of CGI animation?

  1. Lighting

  2. Texturing

  3. Rigging

  4. All of the above


Correct Option: D
Explanation:

Lighting, texturing, and rigging are all essential elements of CGI animation. Lighting helps create realistic shadows and highlights, texturing adds detail and realism to objects, and rigging allows animators to control the movement of characters and objects.

What is the term used to describe the process of creating a 3D model from a 2D image?

  1. Rotoscoping

  2. Motion capture

  3. Photogrammetry

  4. 3D scanning


Correct Option: C
Explanation:

Photogrammetry is the process of creating a 3D model from a series of 2D images taken from different angles. Rotoscoping involves tracing over live-action footage frame-by-frame, motion capture records the movements of actors, and 3D scanning uses specialized equipment to capture the shape of an object.

Which CGI technique involves using real actors' movements to animate digital characters?

  1. Keyframe animation

  2. Motion capture

  3. Rotoscoping

  4. Stop-motion animation


Correct Option: B
Explanation:

Motion capture involves recording the movements of real actors using sensors and translating that data into digital animations. Keyframe animation, rotoscoping, and stop-motion animation are different CGI techniques.

What is the term used to describe the process of adding realistic textures to 3D models?

  1. Texturing

  2. Shading

  3. Lighting

  4. Rendering


Correct Option: A
Explanation:

Texturing involves applying textures to 3D models to make them appear more realistic. Shading, lighting, and rendering are other important aspects of CGI animation, but they are distinct from texturing.

Which of the following is a common file format used for storing 3D models?

  1. .OBJ

  2. .JPEG

  3. .MP4

  4. .PDF


Correct Option: A
Explanation:

.OBJ is a common file format used for storing 3D models. It is a text-based format that can be easily edited and shared. JPEG, MP4, and PDF are file formats used for images, videos, and documents, respectively.

What is the term used to describe the process of creating a smooth transition between different frames in an animation?

  1. Tweening

  2. Keyframing

  3. Motion capture

  4. Rendering


Correct Option: A
Explanation:

Tweening is the process of creating a smooth transition between different frames in an animation. It involves automatically generating intermediate frames to create a fluid motion. Keyframing, motion capture, and rendering are other important aspects of CGI animation, but they are distinct from tweening.

Which of the following is a common software used for creating 2D animations?

  1. Adobe Flash

  2. Maya

  3. Blender

  4. Cinema 4D


Correct Option: A
Explanation:

Adobe Flash is a popular software specifically designed for creating 2D animations. It allows animators to draw and manipulate vector graphics, create interactive content, and export animations in various formats. Maya, Blender, and Cinema 4D are primarily used for 3D animation and visual effects.

What is the term used to describe the process of adding sound effects and music to an animation?

  1. Sound design

  2. Foley art

  3. Voice acting

  4. Audio mixing


Correct Option: A
Explanation:

Sound design involves creating and manipulating sound effects, music, and other audio elements to enhance the overall experience of an animation. Foley art is the process of creating sound effects by physically recreating them, voice acting involves recording dialogue for animated characters, and audio mixing is the process of combining and balancing different audio tracks.

Which of the following is a common technique used in stop-motion animation?

  1. Motion capture

  2. Keyframe animation

  3. Puppet animation

  4. Rotoscoping


Correct Option: C
Explanation:

Puppet animation is a common technique used in stop-motion animation, where animators physically manipulate puppets or objects frame-by-frame to create the illusion of movement. Motion capture, keyframe animation, and rotoscoping are techniques used in other types of animation.

What is the term used to describe the process of creating a 3D model from scratch using software?

  1. 3D modeling

  2. Texturing

  3. Rigging

  4. Animation


Correct Option: A
Explanation:

3D modeling involves creating a 3D representation of an object or character using specialized software. Texturing, rigging, and animation are subsequent steps in the CGI animation process.

Which of the following is a common file format used for storing animations?

  1. .MP4

  2. .OBJ

  3. .JPEG

  4. .PDF


Correct Option: A
Explanation:

.MP4 is a common file format used for storing animations. It is a video format that supports high-quality video and audio. OBJ, JPEG, and PDF are file formats used for 3D models, images, and documents, respectively.

What is the term used to describe the process of converting 3D models into 2D images?

  1. Rendering

  2. Texturing

  3. Rigging

  4. Animation


Correct Option: A
Explanation:

Rendering is the process of converting 3D models into 2D images. It involves calculating the lighting, shadows, and textures of the 3D model to create a realistic image. Texturing, rigging, and animation are other important aspects of CGI animation, but they are distinct from rendering.
