SCC.131 Digital Systems - Introduction to Graphics Flashcards

Flashcards based on lecture notes about Computer Graphics covering topics such as types of Graphics, Display Resolution, Color Modes, and 3D Graphics.

What is Computer Graphics?

The field of computing that deals with generating, manipulating, and displaying visual content using computers.

What are common applications of computer graphics?

Game environments, user interfaces, simulations, movies, scientific visualization, architecture, education, medical imaging.

What are 2D graphics?

Flat images.

What are 3D graphics?

Represent objects with depth.

What are Vector graphics?

Use mathematical equations to define shapes, allowing for scaling without quality loss.

What are Raster graphics?

Use a grid of pixels, which can become pixelated when resized.

What is Display Resolution?

The number of pixels displayed on the screen horizontally and vertically.

How does resolution affect image quality?

Higher resolution means more pixels, resulting in a sharper and more detailed image.

What is a Graphics Card (GPU)?

Hardware component responsible for rendering and displaying images, videos, and animations on a computer monitor.

What is DMA (Direct Memory Access)?

A method for components to perform data transfers without the CPU shuffling bits.

How does DMA enhance system performance?

Enables hardware devices to transfer data directly to and from RAM without involving the CPU for each transfer, enhancing system performance.

What are color modes in 2D images?

Define how colors are represented and stored in an image, determining the number of color channels used, the information each pixel stores, and how much memory the image requires

How are images stored in a 2D graph?

Each pixel contains color information in a grid or table with rows and columns.

What is the RGB color model?

Color images use three channels: Red, Green, and Blue.

What is Palette-based Color Mode (Indexed Color Mode)?

Stores image pixels as indexes (references) to a limited table of colors called a palette.

What are 3D Graphics?

Digital representations of objects that have depth, height and width

What are the dimensions of 2D Graphics?

Width + Height

What are the dimensions of 3D Graphics?

Width + Height + Depth

How does 3D become 2D?

The transformation of 3D models to be displayed on a 2D screen, like a monitor or phone, using a camera perspective.

What is NVIDIA GeForce?

A brand of graphics cards designed by NVIDIA, built for high-quality gaming and real-time rendering, supporting ray tracing and AI-enhanced graphics.
