Computer Graphics & Animation

These flashcards cover key concepts in computer graphics and animation, helping students to review important definitions, processes, and techniques.

What is computer animation?

The use of computers to create animations.

What is one method of creating computer animations?

3D animation, which involves creating objects and rendering them.

What is rendering in computer graphics?

The process a computer uses to create an image from a data file.

What does anti-aliasing refer to?

The process of blurring sharp edges in pictures to reduce jagged appearances.

What is bit depth?

The number of bits used to store information about each pixel.

Define a bitmap.

A bitmap is a collection of pixels that describes an image.

What is morphing in computer graphics?

A transition that distorts two images to create the appearance of them melting into each other.

What is the purpose of keyframes in animation?

To mark important frames during which an object changes, allowing the computer to generate in-between frames.

What are primitives in 3D modeling?

Basic shapes like spheres, cubes, and cylinders used to create more complex objects.

What does real-time rendering refer to?

The ability of a computer to update the screen with a rendered image instantly.

What is ray tracing?

A rendering technique that simulates the way light interacts with objects to produce realistic images.

What is the role of a coordinate system in 3D graphics?

To keep track of the positions of objects in a 3D space using X, Y, and Z axes.

What are Boolean operations in 3D modeling?

Additions, subtractions, and intersections of objects used to create complex shapes.

What is texture mapping?

Applying a surface map or image onto a 3D object to achieve a realistic appearance.
